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
 
I'd follow their directions and see how it goes first, then if needed contact them again... I believe the chip is what runs the ECM so you would need what matches your combo...
