"The un-detectable ECU"


Conversion of the OEM ECU (engine control unit) incl. torque over the entire rpm range, replaced speed limiter and optimized TCU communication (gearbox). The vehicle stays fully diagnosable, an OEM update can't be overwritten. The ECU modification is only possible in D-85139 Wettstetten. It lasts around 5 working days and can be installed in the car or just in the ECU (please provide ECU printout). The conversion is fully reversible without trace.
