I'll let you know how plug and play an MS3 from Rev really is next week.

I purchased a TurboSmart BOV for it last week and installed it yesterday. pretty happy with it so far except I want to source the vac/boost line for the BOV somewhere OTHER than where the bypass valve previously was. This is because both the MS2's MAP signal line and the Boost gauge were teed into this line as well.

I'm keeping the boost gauge and MAP signal vac lines teed off from the same nipple on the back of the manifold and I'm going to Tee off the Fuel Pressure Regulator line (90 degree nipple right after butterfly) and let that be the vac/boost line that goes to the BOV. I will show pictures this afternoon.

Tell me what you guys think.

Doesn't seem necessary, but thanks for the link.

I just need to know if it's ok that I teed this vacuum line here:

Personally I don't like to signal anything from a line with a check valve in it no matter which side of the valve you use.  JMHO

note for future MS users:

pretty much the only thing that you will need to change in your tune will be your fuel maps. particularly in the lower cells and it would be a good idea to make some runs in VEAL to tune fuel in the main acceleration area. because now instead of air being dumped back into the intake, it will be vented away, and there will/should be a slightly more rich condition right at "let-off" which you will have to tune for.

otherwise, RPM and vacuum wise everything ran about the same after the install

does anyone know If I can run a 1.0 mS dead-time on my grams 750cc injectors and/or know what deadtime I should put in MS for the provided flow vs. deadtime sheet?

bump:\

Need to know if running a 1.0mS deadtime will actually work until I find the correct deadtime or if the correct deadtime can be interpolated from the provided chart. I don't understand the fuel pressure vs. voltage.

From the provided chart:

1.042ms and 0.19ms/V

But, IMHO, the chart shows slightly optimistic and sometime strange deadtimes.

Thanks DaveB
So, how did you figure this out? I am curious for both my knowledge and others to do this in the future.
I thought that it would be lower than 1.0 because im running 1.0 deadtime right now in Tuner Studio's fuel settings and thats with the 312cc Toyota injectors.

Injector offset/voltage characterization is non linear curve,
MS2 "understands" the straight line only.
That is why it is best compromise finding.

choose data according to differential pressure and interpolate between 2 points.
I prefer 12V and 14V points

So according to all of that, I should be able to make the following adjustments in tunerstudio and run these injectors. Im providing a image describing what i need to change:
