Hello,
Looks like i have to change the ECM on the engine, Customer supplied a used, known working ECM. Do i need to change the VIN to get it to work or is it plug and play? And if i need to, can i do it with HP?
Thanks

VIN needs to be changed in the ?new? ecm to match that of the old ecm. Not sure with HP Tuners but I do know with Smarty you need a recovery file to apply a VIN change to the ecm. Same goes with calibration change for going from manual trans to auto trans and vise versa.
HPTuners is not capable. You will have to use a smarty recovery file, have someone bench flash it, or find someone local to you that is handy with genuine cummins software that can change it in chassis for you.
Other option is dealership or someone with a pass through device and software like the witech or drew tech
