    Product Description

    The ESS 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.

    ESS S54 NA optimized 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.

    Power is increased by 10-15 HP when programmed for premium fuel (91US/96Euro).

    Throttle response programming is improved over stock.

    EWS system delete available for S54 integration in other cars.

    Euro software conversion is available for US spec cars with euro headers installed (not available for customers in California).

    Custom tuning available on request, vanos timing programming for extreme camshafts also available.

      E46 m3 tune

      Posted by Billy verduzco on Aug 12th 2019

      Definitely feel the smoother response specially in sport mode, wished it got a few more horses from the tune but it was easy to install and I had no issues at all.
