    GM Truck: 6243 PCM on a L31 350

    Hello everyone,

    Does a 6243 PCM from a 2004 Silverado 4.3L V6 have the necessary drivers/hardware to fire the extra 2 cylinders on a L31 350 swap with the appropriate tune/flash?

    If not, will a 0411 PCM still be able to control the 2004 4L60E and communicate via serial bus with my 2004 Silverado gauge cluster?

    Thank you.

    haha, it looks like we're solving it anyhow. I'm researching that 4L60E module for the G Van tune
