Can you post it up, I dont have a 5.3L Coly file to look at.

Just checked my 08 TBSS E67 file and cant find them either. Under Engine -> Fuel -> 02 Trims is where I looked and didnt see anything. I know you must be able to turn them off somewhere!

ok i will i know where to turn them off at but not were to look at them and see what adjustments they are making'
thanks for the help

Check B1511 and B1512, those are the min and max adjustments. To make them ineffective, put them both at 1.00. To see where they are you need to be scanning them. The parameters like this for the short term trims are not in the editor.
