I have a 1993 GMC 3500 HD 7.4 with a 4L80 E . Needed a ECM so I bough a 16147060 from a company ( fl*gship 1) said it was plug and play, got an email saying I had to put my chip on it? Ok but My is labeled as BAMZ (7.4 auto 4L80e ) it look like it is original. the one I received is labeled AWBP ( 5.7 auto 4L80e . But the chip in the unit is a BJLJ (5.7 auto 4L60e ) not sure if I should change the chip and plug it in and cycle it?
Any one have any idea’s
Thanks
