    Default E78 Boost Sensor Recalibration

    Hello Guys,

    We would like to install a 3 bar boost sensor, is it possible to recalibrate it?

    Thanks!

    Yes, B2101 and B2103 should allow you to modify the MAP sensor for a 3Bar MAP. FWIW, the E78 is used on the 1.4 turbo engine in the Sonic, Cruze (1st gen), and Trax.

    Hello,

    Regarding the scaler, what unit is the value b2101, e.g. KPa/Volt?
    Also there is a MAP on the intake manifold and a boost sensor on the intercooler pipe, Could I recalibrate the boost sensor?

    Thanks!

    The unit info is specified on the parameter definition, but the units are scaler/kPa/PSI.

    I dont know about the boost sensor in the intercooler pipe, I only see a Supercharger Inlet Pressure sensor so that wouldnt be applicable to this Turbo application.
