I'm in the process of putting a hellcat engine in my 2017 Jeep GC SRT, I know its possible to use my 6.4 PCM and have it tuned however I would proffer to start with the stock Trackhawk PCM then do additional tuning later once its running ok. I proffer to do it this way so I can be confident the engine is running fine before any tuning, if I use a tuned 6.4, I wont know if any issues are mechanical or tune related. Also by using the Trackhawk PCM it means the PCM will be able to correctly control the bypass valve which is not possible with the 6.4 and needs separate controller.
Has anyone done this? clearly if I use the trackhawk engine wiring then as far as the engine goes everything should work, what about compatibility with the rest of the cars wiring? Can the later Trackhawk PCM work with the 2017 SRT wiring loom without significant changes?
Thanks
