THE HAND-HELD TUNING MODULE / TUNE OR STOCK ON THE GO

 

The RENNtech Hand-Held Tuning Module creates significant gains in horsepower and torque across the vehicle’s entire power band. By modifying ignition timing and throttle mapping, optimizing air-to-fuel ratios, increasing the engine’s rev limiter and modifying boost mapping for turbo-charged vehicles, RENNtech performance software unleashes the true potential of your Mercedes. RENNtech HHT (Hand-Held Tuner) allows you the unlimited ability to switch between TUNED or STOCK ECU programming without ECU removal!

Our proprietary tuning module stores both the RENNtech TUNED file and your vehicles STOCK firmware file. The module plugs directly into the OBD2 port and delivers the file directly to the ECU. Programming takes only a few minutes and the vehicle can be re-flashed any time and as many times as you wish. Tune or back to stock on the go!

RENNtech has been at the forefront of ECU tuning since electronic engine management since the mid-1980s. Decades of experience with BOSCH Engine Control Units, countless hours of in-house Research & Development along with exhaustive testing ensures that our ECU upgrades offer incredible performance gains and rock solid daily driver reliability.
