PIM settings for 3bar map for Powerfc
 

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

scale 43860
offset 0

For GM 3 bar setting by different people
41800 offset 0 tworx7
43500 offset 320 ccarlisi
44000 offset 357 pluto

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.

back from the dead!

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?

I will check tonight. BTW my settings are 45000 and 150 as compared to above...

Just curious what the wrong input here would cause?

Under map watch with just key on it reads 1.55
