Gm 4 Bar Map Sensor Calibration
It is possible that detroit is slightly above sea level and you can use 12 11 in the formula for 1 mile above sea level.
Gm 4 bar map sensor calibration. So i finally got my 3bar omni power map sensor. I tried to change the multiplier and offset but it is not possible to use positive offset in my 16bit ecu 3 bar multiplier 9 119 psia v offset 0 164 psia so i have a useless map sensor right now. This is aftermarket replacement parts. It is buyer s responsibility to make sure parts purchased here is the correct part.
Formula for the gm 3 bar map sensor is v 8 94 14 53 i have no idea why it s 14 53 and not 14 696 rounds up to 14 7 but it works out on gm s chart every time. Options min voltage 08 max voltage 4 88 scalar 3 8 load offset 15 0 filter 10 frequency 0. The first log is with standard map sensor that flat lines at 1 37 bar. The second log is a 3 bar sensor that has been correctly re scaled.
