94/95 LT-UNBRICK Binary Repository

For comparisons, research, and baseline reference tunes, and repairing failed flashes with LT-UNBRICK software, this page contains many stock GM EE calibrations that I have found and organized.

The “Latest Calibration” column shows the newest known calibration for that application. The “Previous Calibrations” column lists older GM calibrations that were superseded by later updates, with the newest previous calibration listed first and the oldest listed last.

Some 1994–1995 B-body and D-body LT1 vehicles share the same calibration, depending on the application, axle ratio, towing package, police package, or commercial-service use. Because of that, a calibration may apply to more than one vehicle model, such as Caprice, Impala SS, Buick Roadmaster, Cadillac Fleetwood, or commercial chassis vehicles.

Special thanks and primary credit goes to Steveo of ECMHack for his original work, tools, research, and contributions to the LT1 community. This page would not be possible without that foundation.

This list is still a work in progress. Some applications are based on GM calibration data, VIN testing, factory RPO information, and community-sourced bins. If you have additional stock EE bins, missing calibration numbers, VIN-confirmed applications, or corrections, please contact me.
