Well, I got my car worked on, and they pulled my battery cables.

My car has been acting funny, and I havent noticed the knock sensor that was put on there by using the CEL. Im thinking my tune disappeared? Can this be possible?

Also, I want to try to reflash my car with the tune the company sent me. Do I need definitions for my 8?

 

tune wont just disappear cause you disconect your batt.

 

sean, do you have the actual rom file? I can reflash for you. hit me up

 

tune is burnt or flashed into the ecu cant disapear

 

If they unhooked your cables, your fuel trims probably reset. Closed loop (cruise) will not be the same until the ECU learns how it needs to adjust. Open loop (boost) driving conditions should be relatively unchanged after batt disconnect.

If you arent seeing your CEL knock light, Id consider that a good thing.
