FCIM and Custon Tunes on SCT.

[20046.0]

Say if I got a 58v FCIM with a mild flash tune. Would I have to revert my truck to stock before I replaced my FCIM? Or could I just throw it on and say if I ever needed to revert to stock with my sct it would work with the fcim.

edit: also guys is there any information where I can learn some fundamentals of injectors and how the cc and nozzle sizes affect horsepower? My current goal is to make around 600rwp I tow a 7000lb trailer once a month maybe 100kms at a time. . once again off topic question here.

No need to revert back to stock when swapping FICM's. The only thing you may have is, you might get a code for the FICM not being sync to PCM, not an issue.

Would this code just be a diganostic error? It wouldn't affect the truck itself?

Based on what I've read on PHP forum, the U0306 code just means the PCM programming don't match the FICM programming. Its a soft code, with no side effects.

The SCT only reprograms the PCM/TCM.

You can fine alot of info on the PHP forum.
