RENNtech is proud to announce our latest line of proprietary BMW ECU tuning for late model vehicles.
RENNtech has been the foremost tuning authority on Bosch and Siemens engine control units since electronic engine management started to show up in vehicles during the mid 1980′s. Our proprietary tuning software and approach for BMW is built upon the same rock solid foundation as our Mercedes line and is completely unique and independent from our Mercedes tuning program.
RENNtech tuning software is developed and tested in house to ensure significant gains in performance and throttle response without sacrificing your daily driver BMW’s reliability. By modifying ignition timing and throttle mapping, optimizing air/ fuel ratios, increasing the top speed limiter, improving engine cooling and modifying boost mapping for turbo charged vehicles; RENNtech performance software unleashes your BMW’s true potential.
