    S_AUJP Version 7 - Now Supports Turbo (August, 2021)

    Revision 2 November 22, 2021
    Provides:
    C4 Corvette CCM Commands.ADX
    For these cars, includes the CCM Commands that must be added to the S_AUJP ADX.

    Updated ADX files to allow cars with 4L60 transmissions to report 2nd and 3rd gear status in addition to the currently available 4th gear status. Details here:


    ***** END REV 2 *****


    Revision 1, October 15, 2021
    Documentation was updated to reflect an omitted description of a correction to the Shift Light logic. No other files were changed. Below is a summary:
    Beginning with the first version of S_AUJP (v4), the factory shift light provision applicable to manual transmission cars was removed because the fuel efficiency portions of that feature were deemed to not be applicable to a high performance application (1st to 4th shift, etc.). The removed factory provision was replaced with simpler logic providing shift indication at only a single calibration-specified RPM. This made the function available to both manual and automatic transmission cars. However, the logic was flawed because not all cars are factory-equipped with a shift light bulb in addition to the Check Engine Light (CEL) bulb. Under certain circumstances, a constant flickering of the CEL and possibly an installed Shift Light bulb was noticed.

    This revision corrects that problem. The CEL now correctly indicates the Shift Point RPM in all cars. Cars with a factory shift light bulb (manual transmission cars), will find that the Shift Light bulb operates in concert with the CEL.

    Also in this revision, the previous requirement to be in-gear for Shift Light operation was removed. Now the Shift Light operates in P/N to allow testing of the light-ON duration.


    ***** END REV 1 *****


    In one BIN, S_AUJP Version 7 (v7) now provides 2 and 3 Bar Turbo support while continuing as before to support 1 Bar Normally Aspirated (NA) engines.

    What v7 does
    • Provides extensively-in-car-tested 1 Bar NA and 2/3 Bar Turbo support.
    • Allows immediately running Boost by merely entering the MAP sensor Bar type (2 or 3), and updating or entering a few Turbo-related values.
    • Automatically handles MAP conversion from 2/3 Bar to 1 bar equivalency for 1 Bar NA operation when not in Boost.

    All feedback appreciated. Happy Boosting!
