    Thought I would share my findings with you guys. I’m running the 12614088 OS with a 6.2 from a GMC Denali that was transplanted into a Street Rod. I did everything this thread listed to do. Without the VATS patch the engine would turn over but no spark and no injector pulse. After the VATS patch we got spark but still no injector pulse. We had to apply a 100 Ohm resistor to pin 52 on the X1 connector to get her to fire up. And yes we tried the G1220 and it made no difference. Hope this helps someone else. This thread was a life saver for us.

    You just added a 100 ohm resistor to the wire on pin #52? Thats it?

    Yep that's it. 100 ohm 1 watt resistor, one end to the pin 52, one end to a good ground point on the frame.

    You guys make me Rafff.. Good job finishline

    I had the chance to change G1220 on the Jeep with the 09' 5.3 and it worked; don't need the resistor or relay anymore.

    Still no go on the 07' with the ******4088 OS.

    That is correct...

    V7 software does the following:
    - scanner,
    - logger,
    - calibration editor,
    - ECM flash reader/writer.

    V8 software does the following:
    - ECM flash reader/writer,
    - V2 setup/options configurer.
