im new to this so pardon my learning curve. im trying to identify a chip that came out of my 85 corvette. apparently the ecu was changed over to a
1227730 ECU. i just dont know what cal is in here and i dont know how to identify the chip that is in here. the chip says HLH Delco 2292. i do have an APU1 to read the chip. but im not sure what direction to go to figure out what is in here .
