Tune isn't taking...

[1fastsedan]

Hi Mike,

I'm having a problem with my Predator writing to my 06 SRT8 (calid: 05030232AF). I've had it for almost 2 weeks. The Predator worked fairly well up until yesterday. Initially I was able to write the tune, but I never did get the raised shift points to work. Yesterday, I put the car back to stock while we installed a new cam - that one wrote fine. Then I put in a modified stock tune with the idle raised to 750 - that one also wrote fine. Now that the PCM has learned the new cam, I want to put my performance tune back in. I've tried 3 different times so far with no luck. I specfically changed the idle in the performance tune to 700 so I could see a difference and it's always still idling at 750 now. The shifts are still soft like the stock tune too. This morning, I restored the original tune and reset the Predator and installed the modified performance tune (with 700 idle) again. I still have the 750 idle. Any suggestions?

EDIT: OK, I played with installing the performance tune again this afternoon. Based on changing the idle, it looks like its writing to the PCM but I still have the soft stock shifts and no raised shift points. So its looks like its more of a TCM issue.

Thanks.

Got your e-mail. Thanks for the help. I'll try it out this afternoon and let you know if that does it.

Hey Mike,

Thanks for the file. It worked great, the transmission is hitting hard and holding the higher shift points. Of course now I need to put 16 in tonight!
