    Custom Flash ~ 5.3 Liter with Manual Transmission

    I use "pay-per-view" OBD2 software.

    I started with a factory stock 4.8 manual flash, then copied / pasted LM7 5.3 engine parameters (Fuel ~ Air ~ Spark).

    The custom flash is for "Off-Road-Only", without VATS / without Emissions.

    I flashed a "mule" PCM with pay-per-view software, then I "Read" the .bin flash from the mule.

    The .zip file includes an EFI Live difference summary .csv file "Read 1GCEK14V32Z186112_4.8 Manual ~ Modified LM7_5.3 Manual_DIFF_Read 1GCEK14V32Z186112_4.8 Manual .csv". The difference .csv file is a list of the factory 4.8 Manual parameters that were changed (custom 4.8 Manual with the 5.3 engine parameters vs. factory 4.8 Manual).

    .zip folder contents:
    Read 1GCEK14T02Z183263_5.3 Auto
    Read 1GCEK14V32Z186112_4.8 Manual ~ Modified LM7_5.3 Manual
    Read 1GCEK14V32Z186112_4.8 Manual ~ Modified LM7_5.3 Manual_DIFF_Read 1GCEK14V32Z186112_4.8 Manual
    Read 1GCEK14V32Z186112_4.8 Manual

    The flash is provided with "Use at your own risk" disclaimer.
