DerekDaniel Posted August 11, 2012 Share Posted August 11, 2012 If your car is tuned.... Is the TCU effected? Hypothetically, if dealers messes with TCU and my car is tuned will something bad happen? Link to comment Share on other sites More sharing options...

fishbone Posted August 13, 2012 Share Posted August 13, 2012 Hypothetically no. Realistically, more detail. A dealer may choose to rewrite the ECU for any number of random reasons. It's happened before and if you have any married AP, you're going to be inconvenienced. The TCU is not programmed by an ECU tune. Link to comment Share on other sites More sharing options...
