    Default CMC High RPM Fueling

    So ross would you like a log of my truck that is on a limiter? Truck used to die at 3300, now it's at 3600.

    New calz are set to 4500.

    Not at the moment sorry Les, I don't have any magic bullets up my sleeve right this minute, I would have to go back and start digging again. Remember I added those years ago but had them hidden, it isn't something I just found.
    Unfortunately I am currently working through TWENTY FOUR! new OS's for just the 2013+ Cummins ECM alone (because of the factory Ammonia Delete), these software engineers are out of control.

    Actually, send the log over so when I have some time I don't need to chase it up again.

    Awesome glad to know you are adding support for them, I had to deal with one a few months ago, what a mess.

    Yeah, it means my month is done for and then some!
    There is two main issues now with the 2013+ that make it even harder, the factory Ammonia delete OS's add fuel to the fire and then the Cummins complier has had an error for a few years now where the 68RFE OS's share the same number as the Manual or Aisin OS's BUT the maps are in different spots. That causes confusion with EFILive so it means we have to map each new OS twice and detect which mapping version to use! Grrrr, should send them an Email asking for that to be fixed

    Any plans to add this to CMD? Also whats the chance you can add the Fan tables to the CMD and CME?

    thank you so much for this boost linearization scaling table. I'm not sure what the units of measurements are on the axis though. I understand the "inhg" one,but there is no label on the other axis and I can't figure out how to scale it for .05-5 volts for the sensor.

    for a 5 bar sensor that is good to about 75 psi, the "inhg" axis should be scaled to 152.7 in hg, but how do I scale the other axis for .05v - 5v?

    Thank you for any help!

    Disregard, I figured it out.

    Sorry I missed your original post, scale it from 0 to 5V by taking the value shown and multiply it by 0.0048828125
    Eg:
    102 * 0.0048828125 = 0.49 V
    920 * 0.0048828125 = 4.49 V
    1023 * 0.0048828125 = 4.99 V


    As you see the sensor must be quite linear as they are relying on interpolation between 0.49 V and 4.49V

    Cheers,
    Ross
