RENNTech Bentley ECU Upgrade



Our proprietary Bentley ECU upgrade offers rock solid performance from RENNtech, the foremost tuning authority on Bosch and Siemans engine control units.

These same units are utilized in Mercedes Benz vehicles, which RENNtech has been tuning since electronic engine management started to show up in vehicles during the mid 1980's, though our proprietary tuning software and approach for Bentley is completely unique and independent from our Mercedes tuning program.

RENNtech tuning software for Bentley offers significant gains in performance and throttle response without sacrificing your Bentley's daily driver reliability. By modifying ignition timing and throttle mapping, optimizing air/ fuel ratios, increasing the engines rev limiter and modifying boost mapping for turbo charged vehicles, RENNtech performance software unleashes your Bentley's true potential.
