I'm not 100% sure on this, but for a 92, I believe you can only change that through editing the computer.

I'll give you a bump though.

Is something wrong with your idle? What's going on?

Nobody knows? If i don't get a reply i guess i should assume it can only be done through the computer and if this is the case...Can i buy an ALDL cable through a laptap and use Tunercat for change timing? Or use LT1_edit?
