Calibration update failed on 2012 challenger RT

[RTchally]

Hello,

I have a 2012 challenger RT. I am not able to update the PCM with the calibration update.
I see others have had this problem and needed to reset the device. I guess I might be giving you fine folks a call.

I am not sure why I would need to reset it though, I didn't have any issue updating it when I first attached it to my PC. It did its update, then I took it to my car, it wanted the calibration file so I took it back to my PC, it updated it with the calibration file. I then took it back to my car, then during the last operation of the update it fails during the key cycles at 99%.

inTune updater, version: 1r01m

Also, If I have a Mopar CAI and a Mopar cat back exhaust, will I be able to adjust a tune to benefit these items?

let it recover, leave the key in the run position, and do not cycle the key, just click the check marks when prompted to.

Thanks

[RTchally]

That did it! Thank you very much.

I also never cycled the key during any of the other processes, and this also allowed the PCM back up and Dablo tune to be written and saved.

I do have a quick question.
If I have a Mopar CAI and a Mopar cat back exhaust, will I be able to adjust a tune to benefit these items?
Would this involve a custom tune?

[mikel]

the cai may want a little fuel added, try 5% at WOT in all 3 rpm ranges.

Is adding the 5% WOT typical with all vehicles when using CAI's ? Just wondering since I added a CAI to my 2012 ram last night & I'm using the 91 tune.

[mikel]

Not uncommon...

Mike,

I have the 2012 durango rt hemi. I just set up the 87 tune and everything is working good even though it took over an hour to get it calibrated with a couple trips to the computer.

I have a k&n cai and bbk 85mm throttle body and removed the mid-muffler. Should I do a 5% increase to the fuel to the wot on all 3 of the ranges? When I change it would it put it to the +(to right) or - (to left)? To the right it says lean. Does that mean the car is lean or that your making the car lean?

Any other paramaters I could change that could help?

Thanks,

Brian

[mikel]

yes, 5% is a good start, move it toward RICH.

[Polish Express]

That is to the left or (-)%, Correct?

[mikel]

whichever one says rich.
