ESS N55 F series E-Flash Stage 1 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 40-45whp range. Catless exhaust option is available upon request.
The E-Flash N55 software is a full OBD2 solution that does not require sending in the ECU or opening the ECU in any way.
Correction factor for drivetrain loss is 15% above RWHP as seen in dynograph (RWHP/0.85) Power rating is dependent on fuel quality.
