2009 Challenger RT 5.7L
Predator U7135 - v.9r231
Part #181183

When i connect to my car for the 1st time i get... Calibration 05187899AG is not supported; need to downgrade to 05187899AE.

I did not do this and tried to update U7135 to lastest crom v.9r30. this did not work and said that hardware does not support update; go back to v.9r12. I did this and now the U7135 won't allow to load a performance tune.

The predator U7135 is now at v.9r12.

Help!!

thanks Chuck

You need the 9r30l, limited CROM. I don't have it though.

I attached 9r29l, which may have that CalID. Otherwise you'll have to wait until Monday.

Thanks for the file and the help. This solved the issue and I got the 93CAI tune loaded. Definite pep added and I would say another 7-10HP on the good old Butt Dyno 😄

Thanks again for the help
