ecm 16161237 (Geo Storm) need info

[1project2many]

Hello!

That's a blast from the past. The 1992 Geo Storm was one of the first gm products using an EEPROM. This ecm could be reprogrammed through the ALDL connector. 1993 Cavalier VL 4 cylinder was also eeprom equipped but I cannot tell you if the programming protocol was the same as the Storm. I do not remember anyone developing software for tuning for the Storm.

Wow so is a internal eeprom, so how can I try the Cavalier programming, I have 3 ecu's to experiment, the interesting part of this is that this "4 dial tuning box" can be use for all gm ecu's if I can reverse ingenering we can use it for boost on any ecu

if you sent me one of the ecms i might be able to write flash software for it but it could take a year due to other projects

Happy to send you a ecm send me your address and will send you the ecm next week
