Spare ECU for tuning? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I suspect there is a security relearn if the ECU is swapped for a spare one?

Anyone have experience with this on a '12 SS?

It has your VIN locked with the PCM in it I believe...you would have to go through a dealer to get a new one and I believe they would require you to send the old one back in

EDIT: From what I've heard.....for what it is worth

and even if it works the mileage and data would be off. the dealer will know. gotta pay to play. dont try to cheat the dealer on warranty

Yes global diagnostics tell a lot, I have replaced E38s here and you have to do a clutch learn, case learn, relearn the immobilzer, etc, not a direct swap over at all.

If you had you would have found the other 26 threads on this topic that say that having a spare ECM for tuning doesn't work on the Camaro.

Ya, ok so I'm a newb here. I'll admit I didn't search. The LNF Cobalt I sold was a Bosch ECU that you could swap back & forth after one HPTuners security seed relearn.

Thanks for the info guys.

Long time HPTuners, CobaltSS, GMSC forum rat, just a newb here.
