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 E46 M3 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)

I have used many mechanics over the years for the many different types of vehicles in our company fleet and southern BM is one of the very few workshops I can highly recommend. Andrew and his team are also really passionate about their work and it shows.

Touched base with Sean to do some coding work on my F85 X5M. Not only was he a whiz with the tech stuff, knowing his way around without any difficulty. Very rare to find someone like Sean - I happily rate and recommend this business for anyone.

Andrew Brien @ Southern BM has been helping me for years with my BMWs - he is extremely astute and has a refreshingly customer-first mentality. I trust him to do the best work and only the best!

Sean arranged a Quaife LSD for my 135i and I couldn't be happier. He advised multiple seals and bearings needed replacing unbeknownst to me so these were done as well. Now I have a more reliable car and one with tonnes more mechanical grip!
