Pin 1 5 volts gray. Anything over 15lbs of boost should run on 3bar.

Mopar Turbo Minivan 3 Bar Map Sensor

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.

Pin 2 signal green. 039 460 883 876 153 2 bar. Map sensor pin swap. Hi i noticed that the zr1 map sensor is listed as a 2 5 bar sensor but if you look at the scaling in a stock zr1 tune file it is scaled at 312 500.

How much boost can a 2 bar sensor handle. I have used it in other applications and found that my kpa is off 100kpa might read 135 which would coincide with the sensor being a 2 5 bar yet why is it scaled by gm at 312 500 when an older style 3 bar sensor would be scaled at 282. This may cause non. Up to 15 lbs of boost.

As soon as i scale the map to the rerquired values 194 for 2 bar and 288 for 3 bar that car runs worse. Gm 2 bar map sensor linear and offsets for hptuners. Anyone come across this. Pin 3 signal to pcm light green gm 1 bar map sensor linear and offsets for hptuners software.

Pin 2 ground low reference orange black. Map sensor assembled in the usa unlike the current delphi production. This is regardless of which map sensor is used. Gm map sensor identification 3 digit numbers for identification.

749 861 the logic module uses the manifold absolute pressure map sensor to determine the absolute pressure not the relative to atmospheric pressure of the air inside the intake manifold and the atmosphere barometric pressure. Calibration is linear with 1 1 kpa at 0 volts and 315 5 kpa at 5 volts. Pin 3 ground orange. Pin 1 5v ref grey.

886 012 539 609 701 3 bar. The factory ecu uses an offset and multiplier function to calculate manifold pressure from sensor voltage when the sensor is changed the output voltage will calculate the measured manifold pressure incorrectly. Thanks for your time. Stock top locking tab up wires facing you.

The flashscan with the 3 bar map reads 830 volts at 55 kpa the flashacan with the 2 bar map reads 1 030 volts at 51 kpa the only way the car runs clean is when the scaling is set to 94.
