The other day i had my tune copied then all that was changed was upping the idle to 999 to stop temporarily from being lean at idle. Tried twice to do a partial write even though i know the pcm doesnt usually accept those then finally did a full re write. After that the T/C light for the trans was stuck on and has been for a few days. Is there an easy way to fix this issue? Is it just some kind of reset? Trying to do this tune on the dyno later today at 9am so hopefully one of you can give me a quick response. Thanks.

 

any codes set with the trans light?

 

no, no CEL's at all.

 

sorry

 

oops
