Help with PCM swap, 0411 to P59
I just purchased a 12586243, drive by wire PCM that will work. Some people say just trim the Red connector on the factory harness and plug it into the P59 PCM and you are ready for tuning. How true is this? I won't personally be doing any tuning. I have a shop a couple hours away I'm taking it too. The last thing I want is to show up and have them tell me I should have re-pinned the whole Red connector to a Green connector. Is this "plug and tune" or is there anything that needs re-pinned other than the flex fuel sensor? I've read about the M6 reverse lockout not working, which I can fix later. Also some say that a resistor needs installed for the tachometer to read properly and the O2 heaters will throw a code. Thanks.
You can't really say what or how a tuner will react, they are all different. Some could care less, some think everything should be a specific way. Every tuner is different, and tune differently.
