Title: In-dash Boost Gauge
Post by: '95MSM on May 21, 2008, 07:10:23 PM
(http://forum.miata.net/vb/attachment.php?attachmentid=64034)

I haven't completed the wiring, but the Speedhut gauge (with a lot of fiddling, cutting and filing to the gauge housing) can be mounted in place of the fake oil pressure gauge.

That is awesome!!! If you have the inclination I'd LOVE to see a howto on that. Then I could put a real oil pressure gauge in my custom 3 gauge set up over my head unit.

Do you can to wire around any of the PC circuits that might have been cut away? Is it a major science project? I assume so.

(For ease of discussion, I'm going to call the gauge housing a cup.)

The Speedhut gauge can be disassembled rather easily.  The silver trim ring screws onto the cup, holding the "stack" together.  Front to rear, the stack consists of the lens, a spacer ring, the faceplate w/ lighting, another plastic spacer and the meter printed circuit board.  Cutting the wires is a "commitment" step, but otherwise you can't separate the gauge movement from the cup. 

Cut the cup back so that the side of the cup projects no further than about 1/8" beyond the faceplate.  The cut edge will not be visible, so no concern for aesthetics.   You will be taking about 1/4" off of the cup, sawing right through the threads molded into the lower set of threads molded into the cup.

There are four guides molded into the cup.  These guides keep the various parts of the gauge lined up.  With the wiring hole down, fit the cup into the area vacated by the OEM oil pressure display.  You'll see various protrusions in the area the gauge mounts in, but no modifications to the stock housing or flexible printed circuit are required other than a hole for the gauge wires.  A notch has to be cut across the top back of the gauge cup to set the depth. Approx 5/8" of the lower side of the cup must be removed and the left side thinned to get the gauge positioned accurately up/down and left/right (the pocket isn't symetrical around the gauge).  I used the piece removed from the bottom side of the cup as a shim between the right turn signal light tower to wedge the cup into position.  I don't think it will require any additional mounting, but if necessary, I'll put a couple of dabs of hotmelt glue to keep the shim firmly in place.

The wiring is too heavy and too inflexible to route the bundle through available space.  I'll re-wire with lighter gauge wiring, and I probably won't bother wiring the electro luminescence face plate.

I hope Axiomtherapy checks back in and sees the thread.  I purchased the used gauge from him & I don't think I would have ever tried this if my starting point was a new $170 gauge.

So there's no big mods needed to the stock gauge cluster? I was thinking that was one big unit on our cars, but I have replaced single gauges on my 91 and I'd guess it must be the same.

Very cool work 95!!

That looks pretty fantastic.  Kudos. 

What are you doing about the min/max set button on the boost gauge?  Will that be accessible through the lens for the gauge cluster?

Or are you deciding not to worry about it?

Great job there, my man.  I once thought about doing that with a real oil pressure gauge in my '01 NB, but it's much better with the boost gauge -- puts it right in the line of sight where you want and need it.  Brilliant!


Title: Re: In-dash Boost Gauge
Post by: '95MSM on May 22, 2008, 12:07:11 AM
I've set the boost warning light to 16 psi and have adjusted the brightness of the alarm LED.  I thought about the features controlled through the push button and decided I didn't need yet another switch (alarm programming, headlight retractor, wideband programming, Link "save" switch, 7 psi max boost) under the dash.

I'll buy a real oil pressure idiot light switch and wire it to the engine warning light or put a red LED in the "ceiling" of the cluster facia.

This really isn't that hard to do.  The time consuming part is modifying the gauge cup to fit the cluster and put the gauge in the right location, and you can do that work away from the car.


Title: Re: In-dash Boost Gauge
Post by: '95MSM on May 22, 2008, 01:55:05 AM
I just got back from my first test drive - the Speedhut gauge doesn't react nearly as quickly as my cheap Equus mechanical. 

I haven't had time to sort out the various boost factors on the Link since I added an external spring to the wastegate.  The Equus would display the 12 to 14 psi cycling that I'm currently seeing.  The Speedhut doesn't.  The connection to the intake manifold hasn't changed.

I had a Westach gauge with basically no damping, it was always wiggling around and it made annoying rattling noises. The Speedhut seems a little sluggish compared to my Autometer, but in the same ball park.

Along the same lines, when I sent my Speedhut back about a year ago, they returned it with a new circuit board, which is a lot more responsive to sudden changes in boost.  So where the old gauge would slowly try to catch up with a sudden increase (like when nailing the throttle at highway speeds) the "new" one rises a bit, then jumps suddenly to the ballpark of the reading, then continues rising.  So I think they've refined its response a little.

Document this mod very carefully.  I think you have a real winner here and I would like to be a follower....

By the way, with the HYDRA I have a blinking Immobilizer light (Hydra quirk).  Sure looks like a good light to use for the missing oil pressure signal. (idiot light)

I looked hard and wide last night for a row of LED's or a multicolor LED (red/yellow/green)that could be driven by a dual switch oil pressure switch or an oil sender like the VDO.  No such luck so far, so maybe the single idiot light will do for the oil pressure.  Would not take much to slide in some LEDs some place on the panel....

95MSM,

This sounds like a mod I'd be interested in doing. It would be nice to get my left-center vent back.

Based on your experience, do you think it would be possible to do something similar with a real water-temp gauge in place of the OEM one?

Skeeler


Title: Re: In-dash Boost Gauge
Post by: '95MSM on May 23, 2008, 08:13:37 PM
Skeeler -

Each gauge is an independent meter screwed into the cluster, so you should be able to remove the water temp and replace it with a real gauge.  The oil pressure gauge area has the added benefit of being framed at 3 points that are nearly concentric to the gauge, so I was able to wedge the boost gauge into place rather than position it carefully via the 3 mounting screws.  At worst, you would need to mount the gauge cup via the three screws.  That would be a little more work to get everything lined up perfectly.

I think I'd do the gauge mod to get more linear results before replacing it. I don't know of any aftermarket temp gauges that match ours as well as the Speedhut boost gauge does, but there may be one out there.

Silverblur, it probably took about 3 hours.  I did it in stages - first taking the Speedhut gauge apart and measuring what was possible, then doing the same with the stock cluster.  After putting it all back together I decided a couple of days later to commit to it.  It probably took 2 hours to do the cut and fit, solder more flexible wires into the gauge wiring harness, install the sender and cable and then button it all back up.

I'm running without oil pressure indicator at the moment.  The whole point of putting the boost gauge in the dash is the A pillar pods look tacked on.  I'll drop an LED into the ceiling of the cluster and buy a "real" idiot switch.

But for now I've got a bunch of work to do on my S2 before I can come back to the Miata.  My oil pressure has been fading the last two races.  I plastigage'd the bearings and they are fine (replaced them anyway - in situ!), so tore down the dry sump pump.  I need a new rotor and gear for the pressure section, but there aren't any in the US.  For now, I've reassembled the pump with the best rotor and gear in the pressure section.  The two scavenge stages are under-worked and should be fine with slightly more worn parts.  I've put out feelers for spare pumps and may pick up a low mileage replacement with known good pressure.

Ressurecting this briefly because I love the idea, if the oil pressure gauge can be replaced with a real one.

http://www.speedhut.com/custom_gauge_description-gauge_type-Pressure-auto_number-678.htm

Has anyone tried that yet?  Note that that gauge series doesn't have the warning LED and respective button which would be inaccessible in the cluster, looks nice that way I think.

95MSM - This looks fantastic.  When you are designing the Speedhut gauges, it gives you the option of supplying your own logo.  Do you have the 'Mazdaspeed' logo you used to create the OEM look of the gauge?  This is a GREAT mod - very clean looking.  Thanks!

Maybe I'll call them and see if they have it on file.  I love the OEM look.  I'd like to do that with a real water temp in the dash and an oil pressure and oil temp in a pod.  That should give me all the instrumentation really needed for spirited driving and the occasional track session.  I'd want to get them all at once to be sure they matched perfectly  thumup

I did this mod on the weekend using a Speedhut Legacy gauge with custom blue backlighting to match my other gauges (I love the look of blue lighting against chrome trim). I followed '95MSM's advice on the install and, like him, found that I needed to insert a plastic shim on the right hand side of the gauge to force it to be centred correctly.

For full details, and lots of install pictures, see http://mx5cartalk.com/forum/viewtopic.php?f=57&t=41091&start=75 (http://mx5cartalk.com/forum/viewtopic.php?f=57&t=41091&start=75)

Here's a summary of the photos:

(http://i490.photobucket.com/albums/rr263/1okie1/MX5_Garage/Boost%20Gauge%20Centre%20Mount/CloseUpGaugeAtNight.jpg)
The boost gauge is a little brighter than the other gauges so its colours bleed when photographed with all the other gauges. Taken close up, this is not an issue, nor is it in reality.

Unfortunately, the gauge's needle does not zero correctly, otherwise it's fully functional:
(http://i490.photobucket.com/albums/rr263/1okie1/MX5_Garage/Boost%20Gauge%20Centre%20Mount/CloseupBadCalibration.jpg)

I read that the Revolution gauges can be recalibrated via their pushbuttons but the Legacy gauges don't have any. On another forum, someone suggested removing power to the gauge and reapplying it so I'll try that next. I fired off an e-mail to Speedhut about this and am waiting for a response, but if anyone else has any ideas, I'd like to hear them.

I love this mod, it puts the boost gauge right where Mazda SHOULD have put one in the first place!

I also recently installed a Speedhut (not in the dash, though I do like the idea) and mine seems to work fine in all respects except that it does not zero either.
Should it zero, when the car is turned off ? If not then, when?
When I turn off the car, power is cut to the gauge and the needle just stays wherever it was when I turned off, which is generally around 20 psi vacuum.
Do I have it wired wrong?

Are these speedhuts mechanical or electrical?  My autometer mechanical always zero's exactly.

Staying where it was when power is cut off makes me think electronic.


Title: Re: In-dash Boost Gauge
Post by: '95MSM on May 17, 2011, 04:10:23 PM
Electronic.

Pop the needle off and re-index.  Turn off the power, turn it back on and examine your results.  It takes me several tries to get it zeroed.

Nice job, and very nice match regarding illumination.  I asked Speedhut if they would sell illumination material for the rest of the dash, but they declined.

But the numbers that it reports under all circumstances other than when the car is turned off appear correct. I get about 22 psi vacuum at idle.
Before I had my MBC adjusted correctly, it read right at 10 boost right before I would hit the boost cut.

Given that all my other readings look accurate, if I reindex my needle, isn't it going to throw off my readings during normal usage?

My speedhut acted strange for a day or two after I installed it.  After a few days, it started to zero by itself.  I don't remember if I power cycled the whole thing or not but it has been fine ever since...

Yes.  It sounds like your needle is below zero at ambient (based on 22 inches when most see 20).  If you get it zeroed, you'll see less vac and more boost.

When turned off, the Speedhut lets the needle seek whatever position it wants, so don't pay any attention to where it points when powered off.

Thanks. After I got home and was able to experiment I was able to see what is happening better. Normally when my car is at idle it shows 22 inches. When I switch the car off, the needle doesn't move. It just stays wherever it was which is usually 22 inches vacuum. But if I switch to ACC, it tries to zero itself after a second or so and you guys are right. It's off by 2 inches of vacuum. I need to reindex 2 inches more boost. Pardon me for being so dense.

I did the in-dash boost gauge mod today and am very pleased with the results.  It is great to retire the old gauge in the left vent and get a little more air conditioning in the Texas heat.  I also like the line of sight in the center of the cluster.  I did not have a diagram for the instrument cluster wiring and found this on MT

http://www.miataturbo.net/showthread.php?t=45024&highlight=wiring+diagram+instrument+cluster

Maybe it will come in handy for someone else.  I wired the switched 12v from the stereo harness.

btw my Speedhut gauge centers perfectly form the first start. 

Thanks for the good info in this and related threads.

hey i was just wondering if there are any other boost gauges that you have found that would fit the in dash install. i really love the look but 160-180 for a boost gauge is out of my budget. but i don't want the a-pillar install and i don't want the eyeball install. do you know of any others electric, or mechanical that would fit and cost under 100. like something like this http://prosportgauges.com/45mm-Boost-gauge.aspx. what is the diameter that the gauge needs to be?


Title: Re: In-dash Boost Gauge
Post by: mr_hyde on August 05, 2011, 04:36:25 PM
Most of the dremmel work is on the gauge itself so it depends on how the gauge is layed out internally.  There is no specific reason it wouldn't work and the concept is the same but YMMV.  If you find another make that works, take some pictures and post back here!

johnandbuddy:

I tried 3 mechanical gauges before settling on the SpeedHut gauge.

You need to disassemble the gauges to do the installation and most gauges have the bezel clamped on so you end up destroying the bezel to pull the gauge apart. This turned out to be an expensive exercise for me and I should have bought the SpeedHut right from the start :(

The reason most mechanical boost gauges wont work is because they have a rear barb for the pressure hose so you'll need to drill a hole in the rear of the cluster to attach the barb to. This means you'll need to cut through the rear printed circuit board which will destroy its tracks so that's not an option.

Most mechanical boost gauges are too deep too. Here's a side comparison of a typical mechanical boost gauge (SAAS gauge - same depth as Autometer gauge) vs the SpeedHut gauge:

(http://i490.photobucket.com/albums/rr263/1okie1/MX5_Garage/Boost%20Gauge%20Centre%20Mount/SAASboostGaugeLeft_SpeedHutOnRight.jpg)

Electrical boost gauges mount the pressure sensor in a separate unit which is then wired to the gauge and this is what makes them easier to mount and allows them to be slimmer.

FYI: After a bit of "dicking about" when I installed my matching SpeedHut AFR gauge in the A-Pillar, the boost gauge now "zeroes" correctly - WooHoo:

Post by: '95MSM on August 08, 2011, 05:19:26 AM
The speedhut gauge is housed in a standard diameter cup (2 1/16th?).  The cup gets modified and in some areas / instances it might even have the wall completely sanded away to be properly centered in the instrument panel.  I suspect nearly all electronic gauges will have similar housing thickness and can be made to center-up in the panel.  The problem is you usually can't tell the depth of the gauge works until you cut it up.  The Speedhut gauge movement is pretty shallow, so it is easy to fit it into the area formerly occupied by the oil pressure gauge.

Lokiel sums it up pretty well - you can cut and try with other gauges and you may hit a home-run.  We know the Speedhut fits.

Post by: johnandbuddy on September 08, 2011, 10:19:36 PM
hey so i was looking into it more and this page says they are 1.25'' deep. the speed hunt gauge is 1.10'' do you think it will still fit, or not. i know it would be a pain but if you guys are in your instrument cluster anytime soon, could you maybe measure and see if 1.25'' would fit?

The depth isn't really a concern. You just need to grind away enough of the side of the housing to make it work.

Post by: Lokiel on September 09, 2011, 02:25:04 AM
One big advantage of the SpeedHut gauge is that its casing is plastic and its external plastic threads are quite thick so you can grind a lot of material off where you need to make it fit.

This may be an issue with metal casings - you may need to resort to a hammer :buck2:

I had a Speedhut gauge installed in an ePod mounted on the steering column and in looking at the photo above I noticed that my gauge does not light up nicely like the gauge in the photo above appears to. At night, my gauge lights up the needle and there is a red glow around the perimeter of the gauge, but the numbers on the gauge do not light up at night. I can see the needle position at night, but not the numbers. Is there a separate power hookup for the gauge face versus the needle ? Do I have it wired wrong or do I have a bad gauge or is that just the way it works ?

I removed the red condoms from the dash bulbs quite some time ago.  My Speedhut gauge is "LED white", though it is actually electro-luminescence lighting it up and not LEDs, so it isn't a very good match for the creamy-white light from the incandescent bulbs.  I checked on LED conversions some time ago, but there were still "hot spots" in the gauge illumination.  A few months ago I asked Speedhut if they would do electro-luminescent pads for the other 4 gauges, but they were not interested.  Bummer - I think the stock gauge faces would work beautifully with EL.

hey thats awesome Simon!

Want!

Where did you get that from? In the daylight does it look like the one in the OP's first post?

Can they read higher than 20psi?

do tell lol

I ordered the gauge from SpeedHut on-line. Mine is the Legacy gauge which tops out at 20psi and doesn't have a button on it (not an issue for me since the gauge is behind the cluster's plastic window anyway).

I haven't tried to test beyond 20psi :P

The Revolution gauges go to 30psi: http://www.speedhut.com/custom_gauge_description-gauge_type-Boost-auto_number-614.htm (http://www.speedhut.com/custom_gauge_description-gauge_type-Boost-auto_number-614.htm) The Revolution gauges have a button on them which you wont be able to use - no biggie. The SpeedHut AFR gauge on the A-Pillar below is a Revolution series gauge.

These gauges are expensive but you can tailor them to the colour and style you want (you can even put your own text or picture on them). Though I didn't explicitly ask when I requested the "MAZDASPEED" text on the boost gauge, SpeedHut used the official MAZDASPEED font which was an unexpected/pleasant surprise.

This is what the gauges look like in the day - the grey face is very close to our OEM gauge faces:

Have you tried these LEDs, they eliminate "hot spots"?

You can find these on eBay if you search for "ZPE Blue dash LED kit Mazda MX5 Miata" (they also have red LEDs).

I installed these in my car and the seller was so impressed he now uses a photo of my dash in his eBay listing.

I had a Speedhut gauge installed in an ePod mounted on the steering column and in looking at the photo above I noticed that my gauge does not light up nicely like the gauge in the photo above appears to. At night, my gauge lights up the needle and there is a red glow around the perimeter of the gauge, but the numbers on the gauge do not light up at night. I can see the needle position at night, but not the numbers. Is there a separate power hookup for the gauge face versus the needle ? Do I have it wired wrong or do I have a bad gauge or is that just the way it works ?

Download the PDF here: http://www.speedhut.com/support/index.php?/Knowledgebase/Article/View/24/6/2-and-2-58-revolution-and-legacy-instructions (http://www.speedhut.com/support/index.php?/Knowledgebase/Article/View/24/6/2-and-2-58-revolution-and-legacy-instructions)

You can see in all the gauges that there are 2 power sources to the gauge:

1. Needle lighting: Red(12V keyed ignition) + Black(GND) + White(+12V Dash Lighting)
2. Dial back lighting: White(12V Dash lighting) + Black(GND)

It seems that whoever installed your gauge didn't hook up the Dial back lighting. I connected the Dial wiring to my dimmer switch.

That sucks, particularly if they haven't updated the description. I guess it was cheaper to manufacture using 4 LEDs vs 6 LEDs. That's what I REALLY hate about stuff made in China; because they manufacture in such massive volumes, saving a fraction of a cent per unit is a significant cost-saving to the company. When smaller volumes are produced, these small cost savings are insignificant.

Woo!  I'm a member of the '95MSM boost gauge install club!  :D
Many thanks to '95MSM and Lokiel!  You guys rock.
Copying below Lokiel's PM to assist with wiring the SpeedHut gauge - VERY helpful!  I used 18-22 quick splice connectors all on the gauge wire clusters, which held up for at least the first test drive.  Wasn't sure what to use for those tiny little wires.  Everything seems to be in order, though needle is juuuuust slightly off "0" at about 0.5.  Shows <20ish vac idling, and steady 8 boost "under pressure".  Car is essentially stock, so I'm assuming it's showing a bit high?  Can't remember what it's supposed to be at - though I'll check before performance mods.

Other than stressing about the wiring, I also generated a decent amount of anxiety while modifying (dremelling) the SpeedHut gauge to fit - felt like I was really working over the little guy.

Anyway, here's the wiring help courtesy of Lokiel:
You're in luck, I found my original notes which I marked up with the wire colours when I did it.

I assume you have the SpeedHut manual which contains this picture (apologies for the bluriness, it's just the first one I found on the internet):

(http://i363.photobucket.com/albums/oo75/jomointhehouse/IMG_2336.jpg)

Top 3 connectors:
+12V keyed ignition(Red) -> Cluster 1C (Blk/Yel wire)
Ground(Black) -> Cluster 3A (Blk wire)
+12V Dash Lighting(White) -> Cluster 3G (Red/Blk wire)

Bottom 2 connectors:
+12V Dash lighting(white) -> Dimmer switch Red/Blk wire (you could also use the cluster's 3G Red/Blk wire)
Ground(black) -> Dimmer switch Gry/Red wire (you could also use the cluster's 3H Grey/Red wire)


The Cluster IDs I referred to above are in the MSM tech files which can be found in the http://www.mazda-speed.com/forum2/index.php/topic,17458.0.html (http://www.mazda-speed.com/forum2/index.php/topic,17458.0.html) thread - go to the last page to find the latest download location. These guides are very handy and worth becoming familiar with.

Figure 19 of the wiring_all.pdf file shows these connections.

Hope that helps.

Once you've done this, could you please update the '95MSM boost gauge mod thread to include this information so that others can benefit from it too?

By the way, also did the oil pressure light and linear temp gauge operations while cluster was out.  thumup
Pics are on phone, will see if I can grab a decent image or two to add later.

millsj, all credit to you and your thread on installing the oil pressure warning light.   thumup
I used the exact bulb and holder you recommended in your FAQ, but wiring was easier since I only used one light and my op gauge is gone.  I put it outside the speedo at about 113 MPH, though in hindsight that's behind my right hand when 10/2-handing it, so not ideal.  Luckily it's bright!  Your lower placements would be better.  And yeah, my son couldn't believe how fast it was to button everything up when I was done.

While I'm giving credit, thanks to mr_hyde for the linear temp gauge re-wire instructions.  That was a piece of cake with complete instructions all in one place, and I am really digging seeing my temp gauge move around as-expected instead of staring blankly back at me.

...Now back on topic before SMR comes in here and kicks all our butts!  ...About that BOOST GAUGE install, I found
1) Getting the SpeedHut wiring to poke out from under it was a bit challenging.  Seemed crowded going around the bends to aim out.
2) Lokiel's technique of cutting an exit hole in top of cluster to be quite useful.
3) I drove the pee out of my car getting to work today so I could watch my vac/boost.   :D

Do you go blind when you turn on the ignition?  Between the shift lights and duel op lights, I need sunglasses!   ;D  Did you wire the light the same way I did-on the sender side of the wiring harness with a diode, or did you come up with some new clever way to wire it?

Well, and I'm not saying this is remotely "right" since I have no electrical expertise at all...  I just hooked the light's red wire to IGN and the black wire to OIL on back of gauge cluster.  It's on with ignition until engine cranks ...so I'm assuming it works.  (Remember, my op gauge is gone gone gone.)


Title: Re: In-dash Boost Gauge
Post by: millsj on October 01, 2012, 06:42:45 PM
Oh yea, that's right.  If the OP gauge is gone, it is much easier to wire.  I think this is the way Hyde has his configured.  One thing is for sure, you will see the LED much sooner than the movement of the OEM gauge!

In hand, I have the recently-purchased-on-sale Speedhut, an Epod and a MSM (well, it's in the drive).  I tried mounting the empty Epod on the column and driving around to see how I liked it - I didn't.  So now I am rereading all the threads on the 95MSM-pionered installation in the original oil pressure guage spot.

One thing that is not perfectly clear is how the gauge is held in place.  Bits of plastic and glue?  Did I miss something?

I'm not squeamish about getting in there; I installed a Camaro cluster in the Impala SS, but I don't want to have to screw with it two or three times to make sure it doesn't move or squeak.

Would like to learn from your experiences and not reinvent the wheel.  Thanks.

Post by: mr_hyde on October 29, 2012, 04:07:37 AM
It kind of wedges in place between the turn indicator extensions.  Hard to describe really, but there isn't a specific, fixed mounting solution.  It takes a lot of free hand dremel work.  Slow and careful with lots of test fits.   :mrgreen:


Title: Re: In-dash Boost Gauge
Post by: '95MSM on October 29, 2012, 05:31:27 AM
At first, I just set the depth of the gauge cup so that the gauge face was held in place by the cluster fascia panel.  That is a bit of a pain, since the boost gauge will float around a little whenever you remove the cluster fasica.  It takes a bit of fiddling to get it aligned and rotated just right.

When I went back into the cluster to convert it to LED illumination, I changed the mounting system.  I drilled a hole in the bottom of the gauge cup aligned with one of the OEM gauge mounting screws.  I use a nut and screw to hold the screw to the gauge cup and then experimented with a washer stack to adjust the installed height.  The boost gauge now stays put, even without the cluster fascia installed.

Have a look from this post in my Garage thread over at mx5cartalk.com to see how I did it.
NOTE: I got my Tacho & speedo mixed up in my description but I'm sure you'll work it out. :dink:

http://mx5cartalk.com/forum/viewtopic.php?p=796098#p796098

Others have done something similar but fitted an LED similar to the first image in that post, I decided I wanted something that looked more OEM.
It only works this way if you delete the factory oil pressure gauge like I did, however I did fit a separate dedicated gauge with it's own sender later on in the centre dash.


Title: Re: In-dash Boost Gauge

Following on from the previous post, here's my description cut'n'pasted from my garage thread.
(With corrections  :P)

Quote
When you remove the dummy oil pressure gauge to install a boost gauge in it's place you lose any indication of what's happening with the oil pressure, you don't even have a warning light anymore! The solution to this is to wire up a separate warning light using the factory sender (it's only a switch anyway), the factory wiring in the instrument cluster and an LED mounted somewhere. It ends up looking a bit like this....

(http://img.photobucket.com/albums/v355/racr20/Car%20Stuff/4AF3992F-ABFF-447F-A040-CF2206A01E7D_zps5xjec19g.jpg)

I'll be doing something along these lines but also will be installing a separate, dedicated, functional oil pressure gauge.

The solution for the warning light above doesn't really work for me as it really stands out on the cluster face as something that doesn't belong there. As a result I went looking for somewhere else appropriate to mount the light when I realised there are two unused warning light positions in the gauge. There's one in the tacho face that says 'HOLD' and has something to do with automatic transmissions, the other is in the speedo face and is for rear fog lights where they're fitted.

I thought, that's perfect, I'll use them both! :mrgreen:

I've always hated the fact there's no indication inside the car if the fog lights are 'on' and it's easy to accidently bump the switch which could result in a fine. :(
So I pulled the foglight rocker switch and with the help of my trusty multimeter determined which wire (it's the green one) I needed and tapped a line into that and ran it up to where the instrument cluster is mounted. Next was to find a way of mounting a globe in the cluster and that's where eBay came to the resuce, I ordered some wired T5 bulb holders which have fitting the same as the ones already there.
http://www.ebay.com.au/itm/5-x-T5-Dashboard-Light-Lamp-Bulb-Socket-Holder-for-Vehicle-Car-/161316289200?pt=AU_Car_Parts_Accessories&hash=item258f333ab0&_uhb=1

I would also be able to use one of these to mount a light for the oil pressure warning.
This oil warning light is where I used a little lateral though.... I thought the word 'HOLD' without the letters H & D is 'OL' which is pretty close to 'OIL', near enough for my purposes anyway. So next was to remove the tacho (done by removing the 4 screws on the back and bending the 4 metal tabs) and paint out the H & D on the reverse side of the gauge face.

Now actually wiring them up is quite simple you just need to find some suitably tiny screws to go into the rear of the instrument cluster.
Here's how it looks with the two fittings installed and wired up.

(http://mx5cartalk.com/forum/download/file.php?mode=view&id=12235&sid=5b77742a6d27113df9b9e31f04368fa9)

The one on the left is behind the speedo and is for the foglight, you attach one wire to the ground point (nice how they're labeled) to the left using the existing screw. The other end has a blade connector fitted which then connects to the wire I ran up earlier from the foglight's rocker switch.

The one on the right is for the oil pressure warning light and, after removing the dummy gauge, you wire one end to the location marked 'OIL' and the other end to the nearby location marked 'IGN'. These two wiring points were previously used by the dummy gauge and you'll need to find some very small and very short screws (only about 5mm long) to bite into the plastic of the cluster housing but not protrude through to the other side where the boost gauge will be installed.

If you use LEDs in these fittings you will then need to test them as they only work in one polarity so you have a 50% chance of getting it right first time. If they don't work then spin the globe through 180 degrees in the fitting and try again! :wink:

Here's the oil warning light in action.

Interesting, the ABS is in a different location on Australian delivered cars......

This doesn't mean you can't do something similar though. Have a look at the back of the cluster and see if there are any unused bulb recepticles or remove the bulb holders (small ones, one at a time) and shine a torch through to see what lights up on the front (the HOLD on mine had a bulb & holder but wasn't wired up).

Hopefully you will find the HOLD in a different location or another suitable unused indicator location.

Post by: SilverMiataRacer on June 16, 2014, 10:19:38 AM
Hold is an Auto Tranny function.  I find it odd that our cluster wouldn't have it.  That would mean they made a special cluster for the MSM?

I joined the club a month or so ago, but just got around to getting pictures.  I did pretty much the standard install with the Revolution gauge, with a minor addition.  I ordered a new face from Speedhut that has a hole for the warning light but asked them to cover up the button.  I then soldered wires to the leads for the button on the circuit board and ran them to a button that I placed on the steering column.  You will notice the black button on the left side of the steering column in the lighted pic.  I wanted to be able to access the peak boost function of the gauge but not see the button in the gauge cluster.  I also installed an idiot light on the top of the cowel for oil pressure warning.  I will be replacing it with a brighter light in the future as it is not noticeable enough while I'm driving.  Hope you all approve.

I really like that install, but I'm certain that with my about-to-be-installed 330MM Momo wheel, I won't see the top of the cluster.  I had a similar wheel in my NA and had that problem.  I got to where I could read the mid range of the tach from the bottom until the needle moved back into view.  So I'm going to make the water temp gauge linear (I was able to see it in my NA) and put the boost gauge and oil pressure gauge in a pillar pod.  I also like that position because I'll be able to see them in my peripheral vision.

I notice that the gauge shows positive vacuum when turned off. Is that typical electronic gauge behaviour? Last reading when engine shut down, perhaps? Mechanical gauges return to zero when the engine is off.

Install looks great!

Speedhut prints these gauge faces one at a time. I'm sure they can do a boost gauge that would put zero somewhere around 3:00 with positive pressure on the bottom half of the gauge. You wouldn't get vac at a glance, but I doubt that you will need that very often.

I've only owned my MSM since October of last year, and it's one of my most favorite vehicles (and I've owned many)!

I'm currently getting ready to do this boost gauge mod (waiting on parts). And while I was in there, I figured that I'd convert the cluster lighting to blue, and do the temp gauge mod too.
My question was, if anyone that has done this boost gauge mod, has used the unused O/D OFF spot as their oil pressure light. I saw it mentioned, but nobody has claimed to have used it.
I was planning on using it and blanking out "OFF" and part of the "D" so it looked like an "L". So it would look like "O/L". Which is as close to OIL as I think you can get.

That would be me! :)

I actually did quite a bit more but I think this is the mod you're talking about specifically.....

With the Australian version that I have the unused spot actually say HOLD so much easier to convert to 'OL'  :mrgreen:

With the whole cluster re-assembled it's completely invisible too.

I also did the blue light mod but went a fair bit further with it than most people do (it also required a lot more parts, work and $$ to achieve).
Here's the final result of the effort that made it worthwhile.

While I was in there, I'm trying to get the needles to light up red, instead of that Purple-ish color that happens when blue bulbs are installed. I'm probably doing it the hard way, but I'm gunna install separate 3mm red leds pointing up at the underside of the needles.
The only other option that I could think of is a translucent glass/plastic paint. But I've seen that stuff come out fairly uneven or splotchy looking. Also I see that you changed the color of your HVAC control lighting. I've heard that is a PITA. Something like the plastic being molded in the original colors, and not just a bulb swap?
Looks very nice BTW!

It's not badly purplish and in all honesty I don't even notice anymore...

I don't think putting separate LEDs under the needles will work well, firstly there's not much room available and secondly I'd expect you will end up with red light reflecting back onto the silver gauge face itself.
The only needle that will will be noticeably more red will be the one on the boost gauge itself (which can be helpful) all the rest will be the same colour.

Yep, the colour is in the dial faces so you need to replace these and use a white back light (either retain the factory globes or use white LEDs like I did).
There's only one place you can get the dial faces from, I.L.Motorsport in Germany, and including shipping it's quite expensive!
Still they have some nice detail in them.

These are the ones you're after.

That's why I'm gunna try the little 3mm ones. Hoping those will be small enough. And as far as the excess light issue, I'm gunna try to block off the back and sides of the leds. Maybe with a foil tape. Either way, it's going to involve drilling holes in the plastic that diverts the light just behind the cluster dials. It's excessive I know. I guess if I screw it up too bad, I'll be looking for a used cluster for some replacement parts.  :laugh:

Yeah... That is a bit pricey. And I didn't even check shipping costs.
Good to know they exist though! Thanks!

I'm lighting the gauges with white LEDs. Glass paint on the pipe that lights the needles was "adequate" for me. Enough paint to get a pure red color makes them too dim.

I replaced the HVAC graphics with films from an early NB, but I don't remember if I "washed" a tint layer off of the graphics or if the OEM green was from bulb condoms.

Another suggestion for an oil pressure light-I installed 2 LED's as my low OP light.  I drive the car on the track a lot, and I wanted something that would jump out at me if I ever had a low OP situation.  I would be concerned that you wouldn't see the OD light, but it's definitely better than the gauge.

Here is a link to how it was done.  It's a lot easier if you are ditching the OEM gauge.

I would agree that if the car does see a lot of track, brighter leds would be the way to go.  Unfortunately for me, there aren't any track options in my area. Closest thing is a 2.5 hour drive to Phoenix. So I'm going for a close to stock look as possible.

I'm lighting the gauges with white LEDs. Glass paint on the pipe that lights the needles was "adequate" for me. Enough paint to get a pure red color makes them too dim.
Tinting the bottom of the needle base was the first thing I tried. And yeah, to get a nice red color it almost made the light output through the needle non-existant.

Here's what I did:  I relocated the immobilizer light over to the OD OFF slot and put a real, honest to goodness oil can light in its place.  My dash is still a bit torn up as I'm waiting for the Speedhut boost gauge to arrive, (and also do the water temp), but I have the oil light dialed in.  I think it is a little more complex than the "OL" from the hold spit and a bit easier than the double LED's.  To make it work properly, you not only need to switch over the wires feeding the gauge & lights, you also need to swap the positive feeds.  The immobilizer circuit is hot at all times, (not ideal for an oil light!) and the OD OFF is hot only with the ignition switch on (which makes programming new keys impossible).  Switch and you are good to go.

This glows red when lit.  I ordered it from revlimiter.net, mine was a prototype that someone ordered sometime in the past and abandoned their project.

I've been toying with the idea of fitting an AFR gauge in to coolant gauge location, in the same way that the boost gauge is done here in the oil pressure location (and having oil pressure, oil temp and water temp in a 3 gauge DIN above a single DIN stereo head unit).

Can anyone comment if this would be possible, is their room back there for this (assuming you're using Speedhut).
