    Swapping ECM

    Eng being forged now.

    Is it a benefit to have a SRT 6.4 ECM programed with my vin?

    Car was a 5.7 and it seems there are a few things different in the 6.4 ECM that are not seen or can't be changed.

    You will need your VIN programed in it, or the security wont let it run. Also you can use a 5.7 pcm, just have to change some things to make it work

    Thanks. Was running my 5.7 ECU with the current 6.4.

    Was looking for info on any benefit to have full 6.4 calibration in ECU, since there are tables that are not seen or changeable with HPT. ie: how it sees the cam timing and such.

    Then tweak ECU to meet my mods.

    Am I just pissing in the wind with this idea.
