WINDOWS XP IS NOT SUPPORTED!). You register your software and dump the binary contents of your stock ECU.  We then provide you a modified binary to load to the ECU with all of our latest developments.


Tables in the ECU that are calibrated:

Throttle control

Valve timing



Rev limits

Shift tables (automatic) 

Torque Models

and much more
