The ESS Tuning S54 Alpha N ECU software is a result of 100's of dyno runs and exact calibration of all parameters to allow maximum performance gains with improved driveability/fuel consumption and stock engine longevity. Removed top speed governor is included, and you have the option of stock RPM limit or up to 9000RPM, default setting from ESS is 8200 unless otherwise instructed. The Alpha-N software is ideal for MAF less intake conversions, such as the Evolve Carbon Airbox
. A intake air temperature sensor with harness is included in the package and must be installed in the intake air-path.
The ESS Tuning E-Flash OBD2 programming system allows the end user to upload the ECU tuning software directly to the car from any PC running Windows XP or newer. The system also includes full diagnostic and code clearing capability. Any future ESS software updates can be received by email and loaded directly to the car. The stock ECU software will be saved and can easily be restored in the future.
