    P01 - 2 Bar Map Sensor - 12615136 - Tune settings ?

    Hello,

    I'm kind of confused about what MAP settings to use, the sensor (12615136), is a Cobalt SS 2Bar sensor, so I would assume you would use the map settings from a Cobalt which is:

    Map Sensor Linear : 270.59 KPA
    Map Sensor Offset : -0.478 KPA

    Yet on the forums I read everyone recommends:

    Map Sensor Linear : 200KPA
    Map Sensor Offset : 8KPA

    So which one do I use? Also, yes the OS has been written for 2bar OS, I'm just doing research before continuing.

    Thanks.

    200/8 are the correct settings for that map sensor.

    Thanks, I guess the question now is, why would the default settings from the Cobalt not work ?

    Thanks again.
