    TunerPro comprehensive XDF for 0411 PCM - with Checksums

    Firstly, I take no credit for any of this. Dimented24x7 was the highly talented individual who made all of this possible. He wrote a flash utility (read & write) for the 12200411 PCM, and also developed multiple TunerPro XDF files for 2001 model year Operating System 12202088.

    Several years ago when a "free" flash utility appeared to be on the horizon, I began work on merging and streamlining the multiple XDF files created by Dimented24x7, into a single comprehensive XDF file.

    When the free flash utility failed to emerge, I abandoned this XDF project.

    After reading numerous posts over the past few months, I realized that there were people still trying to make all of this work.

    So, I recently finished what I had started several years ago.

    Please read the attached PDF document BEFORE using the XDF files. You must make certain that the attached DLL file (plug-in) has been saved to the correct folder on your computer, before the initial opening of the XDF file.

    Safeguards (maximum & minimum limits) have been placed on all of the parameters, to reduce the risk of a flash that could damage (brick) the PCM. All parameters include narrative comments to assist the user with better understanding what the parameter does, and what units (e.g. miles / PSI / seconds) the parameter uses and references.

    These XDF files are for use with the 2001 and 2002 PCM (512Kb), with Service Number 12200411. The Operating System (OS) in the PCM must be either 12202088 or 12208322.

    Vehicles that used OS12202088 in the 2001 model year:

    - Camaro & Firebird (5.7L V8)
    - Corvette (often upgraded to OS12593358)
    - Holden (many models - some were upgraded to OS12225074)
    - S10 Pickup & Blazer (4.3L V6)
    - Astro & Safari minivan (4.3L V6)
    - Full-size truck, SUV, and van (including 8.1L engines)

    OS12208322 was an upgrade of OS12202088, mainly for light duty trucks. Vehicles that used OS12208322 in the 2001 model year:

    - S10 Pickup & Blazer (4.3L V6)
    - Astro & Safari minivan (4.3L V6)
    - Full-size truck, SUV, and van (including 8.1L engines)

    As you can see from the above lists, you could run just about any early LS type engine (using a 3x, 4x, or 24x Crankshaft Position Sensor), and the accompanying transmission, using either of these two Operating Systems.

    The ZIP file attached contains two XDF files, one DLL file, and one PDF document. Please read the PDF document before attempting to use the other files with TunerPro.


    *** discovered intermittent display issues when attempting to use these larger XDFs with older versions of TunerPro - sometimes a table will open, but will be blank ***

    *** update to TunerPro Build 5.00.8944.00 (released December 2016) ***
