I have a 730 ecm variety from a 92 Camaro 3.1L V6. Does this ECM have all the programming and tables located in the EEPROM (MEMCAL) or does it contain some of the base program in ROM somewhere else on the PCB? I'm curious because I need to get it reprogrammed to remove the EGR, AC, AIR, and VATS functions. Mike Pilkenton
