    rescale the Cylinder Airmass in the High and low octane Is it possible ????

    Is it possible to rescale the Cylinder Airmass in the High and low octane (Main Spark Vs. Airmass Vs. RPM open throttle tables) . Right now the table only goes from 0.08 to 1.20 , I would like to make it go up to at least 1.95 . If this is possible will you please explain to me how you do it thanks for your help Steven

    OS means operating system, Gen 4 has several.

    If you are maxing out at 1.20, you can rescale your IFR and MAF to shift the scale higher.

    This is what you are looking for. What year is your car? Changing the scale of the table is only possible in the latest cars.

    On all OS systems it is possible to alter the cylinder pressure cell hit.
    Meaning that if you are hitting 1.20 at 10 psi and you need more resolution to say run 15 psi, you can make 15 psi equal 1.20 cylinder pressure.

    Can you give more detail on how this is done please. The axis is not configurable on my OS.

    I can rescale the MAF sensor and the IFR which skews all the charts but I can't figure out how to actually change the axis to read differently. I can change it in the Scanner but not the Editor. Please explain how you are doing this.

    Only later operating systems allow you to rescale the spark axis labels. 06s didn't get the capability.

    You cannot rescaled the spark axis but you can manipulate the stoich commanded AFR, IFR and MAF signal to raise or lower cylinder pressure cells being hit.

    You most certainly can. Open a 2010 Camaro file.

    OP is asking about an 06 Vette.
    You cannot rescale the spark axis on an 06 Vette OS.

    While correct about 2006, the OP is not talking about a Gen IV. There were Gen III that stopped at 1.20. Gen IV goes to 1.36.

    It is not a limit on all years. Scaling on non adjustables is very simple. I'm quite familiar with it.
