I recently purchased a PPEI autocal for my 2013 LML along with a new exhaust. When the autocal arrived I followed the instructions and attempted to do the "Full 1A Flash" option. When I pushed OK it went through the checking process and then instantly popped up error code $0531, which is documented as "Serial number in tune file does not match controller's serial number".
I first double checked the VIN that I entered when I purchased it and everything looked good so I contacted the dealer I purchased it from who walked me through it again to make sure and I got the same result. I sent him all the info on my truck and tuner which he passed on to EFI Live and is waiting to hear back from them. It has been over a week now and I still have not heard anything. I have tried removing all unnecessary fuses and turned off my phone (to keep bluetooth from connecting), in an attempt to eliminate any interference but have not had any luck.
Just wanted to see if anyone else has had a similar problem or maybe has insight on what else I could try. Hopefully I will hear back soon but since I have already installed the new exhaust I only have 100 miles to drive before it limits me to 65mph. I would like to keep the dealer anonymous as I am not trying to complain bad talk anyone, I just want to be able to drive my truck again.
That being said, any insight is greatly appreciated!
