Reason I ask is found a peculiar bcc that iirc came from a 95 k1500 5.7 5spd, but I am not sure. The reason it is peculiar is that it has 3 letters and a number. BHA8 I did not, regrettably, take note of what ecm I took this prom from.
I tried searching known ASDU and got the same error.
I am converting a C1500 w/NV3500(MG5) from 4.3L to a stock 5.7 tbi. I should have checked my truck to see what ECM it had before making the 300 mile journey to the junkyards in Vegas. Not knowing what ecm I had, I grabbed several proms from differing ecm/engine/trans combos, and even got a 6396 BDUJ complete ecm. Turns out I have a 7427 ecm with the 4.3 m/t BJFD. According to my searching, the 7427 can run several different codemasks from other ecm's. I am hoping someone knows what this BHA8. Just to be sure I'm not blind I have attached a pic with both proms. If anyone wants the 6396 PM me, it will just sit on my parts shelf until then.
