Ok so i recently purchased a 2011 Jeep Sahara JK and lifted it and put 35s on it.
*Summarry*
Put a tuner in vehicle, went to return to stock and had issues. Finally got a "successful" restore and backup but motor was idling at extremely low RPMs, not running to good, and AC was not working. Tried to reinstall tune but couldnt because of tool not marrying to the vehicle. I think the mapping is messed up and crossed up and isnt properly being read by the ECU causing the electrical system for the AC to malfunction.
Question is do you think a factory reflash by a MOPAR PCM from the dealership will fix this or am i in to deep and have to purchase whole new relay and electrical system for AC and or replace ECU? PLEASE HELP
*Full Details*
With that said, I was getting bad gas mileage and poor performance so I purchased a Diablo Sport Trinity T1000 and tuned the jeep and it was an excellent tune.
But here is the problem, I went to restore the tune to factory to bring it in to dealership for oil change, tire rotation, etc. So i didnt want that tuner to be in there and void warranty.
Well upon restoring the factory tune, something got crossed up in the mapping. At first the tool told me unable to restore and back up factory tune then brought me through some other attempts and steps and then finally "successfully" restored the factory tune.
Once I had the "successful" restore i went to turn the jeep on and it hesitated to crank like it was starving for fuel then caught and cranked, turned on AC like i normally would and when i did that it was blowing strait hot air and the compressor was not kicking on or engaging. Also at idle the Jeep drops to an extremely low RPM like it will die out but never does. I tried to redo the tune and tune it back to MPG Booster to see if that would correct it and it wouldnt even let me tune the vehicle saying it wasnt married to a vehicle when it had previously "successfully" restoredand backed up the factory tune.
Anyways still no fix, no idea what tune and what mapping is going through the ECU and still no AC.
I think the ECU just needs to be reflashed to factory and i should be good to go but im not sure what to do here or even how to go about contacting the dealership to flash the ECU and how much it would cost. ANY HELP WILL BE GRETFULLY APPRECIATED. I live in southwest Louisiana and no AC down here is no joke lol.
