Well my buddy insisted on plugging my 07+ unichip into is 06 tc I told him it was a terrible idea but to go for it if he wanted and it would probably mess his car up so anyways we plugged it up tried to start his car it automatically dies so we unplugged it plugged everything back up normal and reset the ECU by unplugging the battery for 2 minutes plug it all back in star it up car now won't idle at all if you let off the gas it dies suggestions?

 

Let it relearn its values

 

Yeah that's what I told him I gues that its starting to idle again lol would it be cheaper to get an 07+ ECU or get a new unichip harness

 

Wow, you and your buddy are idiots. But it's your investment, so why not just plug something in to a car it's not made for.

 

More like my buddy I could care less what he does to his car and I gave him fair warning

 

Pinouts are compketely different, I wouldnt be supprised if you have some fried sensors on the 06 now.
