Terracar please give more details about your setup. How much boost were you running and so on...

I've read about the rx7 injector setup in the past but at that point I would want to go full stand alone or at least run a good piggy back. Actually I rather just put the key in my other 3sgte powered MR2 at that point and drive it instead. (-: I'm only looking to go from 130hp to around 190hp on my NA. I'm not planning on running high boost levels and I want to keep the great gas mileage while cruising and overall stock driveability. Just would like a little more power when I put the petal down on my NA.

A big problem that I would want to avoid with the 2 bar map is at full throttle the ecu is only seeing half the load. This means the timing would be insanely high and this would put me at a very unsafe level right off the bat. Then I would have to have a btm or other device to yank the timing way back to keep the engine together. Don't get me wrong I think some type of knock/timing control is always a good idea but I would want to avoid making the timing even more radical by tricking the ecu in the case of the 2 bar sensor. I like the FMU idea because its cheap, simple and proven.

Does anyone have dyno logs of their timing advance while NA and then after adding the 2 bar map? That would be interesting to look at.
