Alright forum members, FNG here in the tuning world with computers. Did my research, tried to educate myself, but still managed to screw things up and need your help. pretty sure I'm not going to like the answer. With all that said.
Went to the repository and found a GMPP tune for a 2008 Saturn Sky, figured that'd be a good place to start. Did a read entire and have my base program, made sure battery on laptop was fully charged, down loaded the 08 tune and went to write entire into my car, but didn't change the VIN in the 08 tune and I think that's where I screwed up. Anyhow the load failed with the 1C0000 code somewhere half way thru the load. Now nothing no comm with the VCM. Tried to write the original file back down, even tried to write calibration only, nothing dead in the water.
Also have problems with the scanner, going to post that in the right spot hopefully. Thanks for any and all help, hope you all had a Merry Christmas! Sent email to tech support, waiting on reply
