Description

Mailing list for discussion of the software contained in the 1G and 2G Turbo DSM ECU's.

The purpose of this group is to dissect the code from the factory ECU for a better understanding of how it works, and to eventually make modifications to improve on the factory code. Any assistance would be appreciated. If you would like to join the list, please do so and introduce yourself when you do.
