Map Sensor 101

Did a [size=50]little[/size] searching on adjusting a MAP sensor via voltage.

What I found calls for MP sensor voltage change in 3/4 and WOT throttle.

From a couple posts on this forum. Seems (suggests) that you folks have expanded things a bit and are able to change MP influence on smaller throttle positions.

OBD 1 or OBD 11 only ?

I`d like to play around with low and mid range tuning a bit. Being limited to fuel pressure alone is not the best way to go.

Hopefully a Mega Squirt is in my future but it may be a bit before that happens.

Changing the MP voltages at lower RPMs and not WOT (closed loop) just changes the fuel trims.
