ESS Tuning was founded in Aremark, Norway in 1995, providing supercharger solutions to the mighty BMW platform. Since then, they've amassed a legendary reputation as the largest BMW supercharger system manufacturer in the world, and as a well-known innovator in the chip and ECU tuning sector with an extensive expertise in Bosch and Siemens engine control systems. In the quest for true uncompromised performance, no one rivals ESS Tuning.
The perfectly optimized ESS Tuning S54 naturally aspirated ECU software for the E85/E86 Z4M 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 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.
Correction factor for drivetrain loss is 15% above RWHP as seen in dynograph (RWHP/0.85)

My first dealing with Southern BM was a pleasant one. I had some springs and shocks installed and Sean was a delight to deal with. Knowledgeable, helpful and offered solutions when not everything went to plan. I would happily recommend them.
