I picked up a 2007 MSRT PCM for my 6.1 swap. I have not yet pulled the 5.7 engine or PCM out, but when I do the swap can I just install the 6.1 PCM, hook up the Appcar, and rewrite the car's VIN into the new 6.1 PCM? Is it that straightforward?
(I am aware that I can just have the 5.7 PCM retuned for 6.1 but want to keep that PCM with the 5.7 for a future project)

yo im doing a 6.1 swap did you ever get the vin swap done

Yes, I did. If possible, think you are better off putting a 6.1 tune into your original ECU than swapping ECU to 6.1. The ABS module does not like seeing “6.1” in ECU and generates “implausible information” code and ABS and traction control lights stay on.

Did the car have any other issue did it run fine with all those abs codes and what not? and also you used appcar to change the vin yourself or what did you do to go about the situation
