$EEHack

EEHack is a free program designed to do interesting things with the datastream of your 1994-1995 GM LT1 engine.

It’s intended both for beginners and advanced users, and focuses mainly on tuning.

It contains modules that allow you to control engine parameters in real-time as well as perform advanced datalogging tasks and upload/download the calibration from the ECM.

It does nearly everything you’d want to do with your ECM except actually edit the bin (that’s what the EEX definition is for…)
