ESS M2 Competition S55 ECU software is a result of extensive testing and exact calibration of ECU parameters to allow significant performance gains on a stock or lightly modified car (intake/exhaust/IC). The Stage 1 software is developed and tested in extreme heat as well as extreme cold temperatures. Typical gains are in the ~100whp range.
The software is available from select dealers or by sending the ECU to an ESS distribution center for the software upload.
