ESS F87 M2 Competition S55 ECU Performance Software




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 in the Arizona desert as well as extreme cold temperatures in Scandinavia. Typical gains are in the ~100whp range. Catless exhaust option available upon request for areas of the world where this is legal.

The software is available from select dealers or by sending the ECU to an ESS distribution center for the software upload.
