ECM Repair Bins

If you’re repairing an ECM and using an EEPROM programmer (NOT flashing through the ALDL port with a tool such as EEHack), writing an ordinary bin file will not work for you.

When GM built this ECM they re-ordered the address lines to scramble the bin.

Here are some of those bin files. If you write these directly to an EEPROM, afterwards you can flash an updated calibration via the ALDL port.
