The 1227750 ecm is used by the 87-89 Cadillac Allante and was hoping that a disassembly for any of the PROMs might be available. I have bins of ADBC, AHWY, AKAA, ANSU, APJZ, & APNF all 27C256 PROMs. and have disassembled some but are uncommented. Usually I can key off the coolant fan setting but these are different. Ludis does not have, nor does Moates or TunerCat.

Does anyone here have either a disassemby or even just some switch table locations ? Hoping for a crib so do not have to trace all 19,000 lines. Do not want to replace with a 16132240 but is documented.
