    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.

      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.
