I know that Chris said that if your ECM had ever been replaced under warranty then the calibration numbers wouldn't match and you could get away with a tune. But if your engine has been replaced, would the numbers match up anymore with a different motor in the car?

    And I will get that video a little later when I have someone to help me.

    even if the PCM was replaced the calibration numbers are still gonna match on GM's approved number list. and yes the numbers would match even with a new engine since the PCM has the calibration numbers

    Remember if "the" and "and" are spelled right its not a genuine Ahuhn post


    Dear God, please send clothes to all those poor ladies in Daddy's computer. Amen.
