    Map sensor maxing at 85 KPA

    Does anyone know why a 1 bar map sensor would max out at 85kpa? My settings are 94.43 linear and 10.33 offset.

    GM sensor 1264428

    Its on a Fast LSXRT manifold on a 2002 6.0l

    Do you live at 7,000 feet above sea level?

    nope in California with a Baro gauge that reads 30.2. So the map sensor for some reason is off. Can i re scale it?

    No, can't scale it. The settings must be accurate for the sensor you are running.

    You probably have the wrong settings for that sensor.

    128.20 and -0.30 should be the settings for that sensor. That is the newer MAP sensor for the later model GM cars/trucks.
