Help Me Get Back to 9r12

[DaveS]

I have a U7135 predator and an 07 dodge charger RT. I updated to the latest crom today 9r29 and after installing the 91 octane performance tune my car won't shift or go over 2900 rpm. I tried to install 9r12 but it says I can't go back to a version prior to 9r27. Can someone please help!

I also have a U0101 code and after I clear it the check engine light went away, but the ESP/BAS light stays on and the light with the skidding car is also on. I want to fix my car so I can drive it please, can someone lend any suggestions.

Tried going back to the stock tune but still have the check engine light and other lights...didn't try to drive it as I don't want to get the car stuck somewhere.

Those lights are for the ESP system. You didn't try to disable it, did you (Dyno Mode)? You can drive with them on, but you won't have any electronic safety nets. No ABS, No ESP, No BAS, No Traction control.

No after I installed the tune they are on, along with the check engine light. I tried to install the factory tune and I have the same problem.

I have been successful at installing tunes many times until this one. My car is not really functional now and I can't revert to a previous version, I need help!

Did u tried to unmarry the car and reinstall everythyng back again?

If you mean to set the car back to stock I had to to get it to update to 9r29. I have no idea how to get the tuner to go back to a version prior to that.

I got the car running again. This time before i backed up the original stock tune I went to the quick adjust menu and reset the TCM adaptation, increased the shift firmness, and enabled the ESP. I checked for trouble codes after and didn't have any. Then I selected to install the 91 CAI tune and backed up the original. Then just installed the 91 CAI tune without modifying any parameters. Started up after it was all done and had no error codes and the ESP/BAS lights were off. Took it for a drive and all seemed well (whew). Not sure what was causing my problems, but these steps may help others with this problem. It might be the new Throttle Booster that was causing problems as that was the only thing I changed the 1st and 2nd time I went through all the normal steps. From looking at other posts it seemed like that setting should work on my 07 dodge charger RT?

Anyway thanks for those who responded, if you have any more suggestions or comments let me know.
