Autotuner has added OBD Virtual Read support for the Bosch MED17.1.62 ECU on the AutoTuner One personal flasher. It is listed as official support, not beta, and it brings a handful of performance petrol engines from Audi, KTM and Volkswagen within reach of the diagnostic port. If you run a garage that works with these cars, it is worth knowing about.
Which ECUs
The ECU is the Bosch MED17.1.62, built around the Infineon TriCore TC1793 microcontroller. The mode is OBD Virtual Read, so there is no need to remove the control unit from the car. Autotuner quotes an instant read of the virtual file, an 11 minute write, checksum correction and a back-to-stock function. A Secure Gateway is present on these vehicles.
Cars this opens up
The source names the following applications:
- Audi: the 2.5 TFSI five-cylinder engine, used in the sport models
- KTM: X-BOW GTX and X-BOW GT-XR
- Volkswagen: Atlas and Teramont with the 3.6 V6 FSI (VR6) engine, from 2018 onwards
Autotuner does not name specific Audi models, so we are not going to guess at them. If you are unsure whether a particular car is covered, ask us before you quote.
What it means
For owners of these engines, this is another route to a proper calibration without the car being stripped down. The 2.5 TFSI in particular responds well to a good map, and a tidy OBD read keeps the job quick and the car off the ramp for less time. As always, any power gain depends on the car, its fuelling and its condition, so we only quote typical figures after looking at the vehicle.
For dealers, OBD Virtual Read means a fast turnaround and less risk of a mishap on the bench. Our tools now read and write this ECU, and the file service covers it for garages who would rather send us the file than do the tuning themselves. You can see the full range on our Autotuner page.
Owners looking at what is possible for their own car can start with our tuning builder.
