     I have programed My 05 impala 3.4 v6 with the fuel trimmings. when I disconnect the Autel they return back to stock numbers. How do I program the fuel trim to keep after I've disconnected the Autel?

     Why are you trying to change you fuel trims? Correct me if i am wrong, but the PCM will adjust those trims as needed, based on demand. What tool are you using to do this?
