[QUOTE="stevens11bravo, post: 14132887, member: 157924"] My tuner had very old firmware 1.2.134 so I returned my car to stock and downloaded the the Update Software from SCT's website. I used the auto update feature and the first time it stopped doing anything midway through the update so I did it again and it said it was successful. Now when I try to program my car it goes through all the steps loading to 100% in everything but then at the end I get and error 1034 saying it wasn't successful and to re-install my factory tune if the car doesn't start. The car will not start so I then re-install my factory tune and it starts and runs. I tried it twice with the same end result. I rechecked the tuner with the auto updater and it shows that it has the newest software so it will not reload anything. I am curious if re-installing older firmware back onto it may fix my issue but I can't find any of the older versions. If anyone out there has version 1.2.134 or 1.2.142 in a file that they could email me, I would greatly appreciate it. If you have another solution feel free to post. Car is a 2012 GT with a JLT intake and full exhaust so it runs like crap right now with the stock tune mainly due to the intake. SCT can hopefully help me but there closed til Monday but I would like to get it fixed now. Just to reiterate, I did return the car to stock tune from a sct strategy tune before the update, tuner had firmware 1.2.134 on it, I used the auto update and it installed firmware 1.2.159 tune version 2.09PFDUS. Let me know if you have a solution or an older firmware I can try. [/QUOTE]
