P0605 on '10 GT500 but runs fine

[jlttuning]

I recently did a CMR tune on '10 mustang GT500. car runs great. i started with the original backup pulled off of the intune. made my changes on the dyno blah blah. all went well but now the owner is saying p0605 shows up periodically.

i never got a checksum error in cmr (if it even has them) or on the intune when flashing. the car runs fine even with the CEL on.

the only thing i can think of is maybe the "stock" tune on his car was not stock. the owner bought the car as is with an intake and slightly smaller pulley. cmr never gave an error nor did the intune when we tried the caned tunes.

i'm not sure if the canned tune throws the same cel and i know stock it did not have any codes

can you post up the tune files?

chances are the P0605 switch simply needs to be disabled.

Thanks

i'll try disabling the code first. i didnt think about that. i'll post up the files if that doesn't work
