Product Image EVOLVE BMW x35i ECU Remap



+70bhp/90ft.lb Remap + Evolver remote tuning tool

Evolve are at the forefront of BMW x35i, 3.0 twin turbo I6 performance tuning with our N54 ECU and performance upgrades fully tested on our dyno as well as countless hours on track and at the Nürburgring.
Being one of the first in the UK to upgrade BMW's 3.0l twin turbo engine we have an indepth understanding of how to go about turning the N54 into a true M3 beater.
Our tunes deliver significant power increases while concentrating on engine safety or drive-ability. Our upgrade is a fully integrated and highly developed ECU remap. 
Through careful remapping of the factory BMW DME tables, various elements such as ignition timing, boost pressure, fuel delivery, and part throttles are reworked to create performance gains. On a completely stock vehicle we can tune a 335i to a realsitic 370bhp with 90 ft.lb extra torque safely.

Our engine tuning philosophy is to improve driveability and enjoyment. We do this by giving an increase in power and torque for the whole rev range, and not just a 'glory' BHP figure found at high rpm where you don't spend the majority of your time. Our Dyno Dynamics output figures are also very conservative and can easily be replicated on other dynos.
