Industry Leader

We are proud to be the pioneers that jailbroke this so-called untuneable Bosch MED17.7.2 ECU equipped in CLA45 and GLA45.  We were the ones that offered this ECU tuning technology to the worldwide wholesale ECU tuning market. We will remain the leaders in ECU tuning technology and provide around the clock customer service to our dealers and private label tuners.


TCU tuning is also available with 40% shifting time improvement.

ECU Tuning Module

Concerned about factory warranty?

TunerWerks' ECU tuning module is the answer. Power gains are identical to flash tune. Don't be fooled by piggyback systems on the market as they fool the ECU and may void warranty. Our tuning module is waterproof and comes with 3-year warranty. Available for most late models. Please contact us for details.
