    Service #16244210 PCM, 4.3 vortec swap into 1946 Chevy Truck

    I have inherited a project from my "father in law" and he is now no longer with us.

    He swapped a vortec 4.3 of unknown vintage using a painless harness. That harness calls for PCM #16244210. Truck is to the point of ready to fire but the current PCM that he purchased does not have that service number.

    1. Is it possible to use a different PCM than what is called for? I do not know if this PCM has been tinkered with.

    2. Does HP Tuners support anything like this?

    3. Am I looking at swapping the PCM to the 411?

    Any help will be greatly appreciated.

    What computer do you have?

    Those "black box" computers are supported but only if it's from 1998+.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
