Does anybody have the PIM settings for using a GM 3bar map sensor on a Power FC for a 3rd Gen RX-7?

Anyone know what Apexi would say? Why such different numbers?

It depends on your desire to calibrate the map sensor to achieve a near perfect conversion of the p-row pressure units to actual boost/vacuum in the manifold. I think this is not necessary since you will be tuning your fuel and timing values anyway and if you use any of the setting combos above you will be close enough to use a starter map for tuning without having to worry much about being in a lower p-row that your actual boost values.

Question. If you have the wrong or differant settings can this give false readings? example: reading 1.2 bars on a .9 bar gate spring?

What does it say when the car is not running and the ignition is on? 0.00?

Just curious what the wrong input here would cause?
