    Default 2010 CMD Map sensor scaling

    Would it be possible to have the MAP-A sensor scaling mapped out? Or perhaps a gracious tuner out there has found it and willing to share a .cax with the rest of the class?

    I've been running a 67/67 VGT I built for little over a month now and while I have mechanical gauges for boost/EBP it would be FANTASTIC to scale the sensor and upgrade to a 5bar/75psi sensor and have it in the logs to match the factory EBP sensor readings.

    Any updates on this? Map sensor scaling (sensor scaling) would be a game changer for the cummins. I have tuned gassers for years and sensor scaling is critical for boosted applications. I have enjoyed tuning diesels too but am surprised by the lack of sensor tuning options for them. The safety features that could be implemented using aftermarket map and egt sensors wired into the ecm would be excellent and is much needed! This seems to be the major missing link in diesel tuning unless you are a software engineer ( I am nothing close) and can figure it out yourself.
    Thanks for making a great product EFI live!

    "A game changer", really?
    Anyway I'm not sure why but we do have the sensor scaling in the 2013+ ECM but not the 2010-2012 ECM. The factory setting has an upper value of 350kPa (50psi) FYI.
    I have made a note in the 2010-2012 files to add in the sensor scaler the next time we are modifying those calibrations.

    Maybe game changer was an overstatement. I think I clarified a little more in my other post. Delete this if needed.

    Thanks for the great work!

    Nick are you needing to read above 50 psi?
