Audi A3 2.0 TSI 200km - MED9.1

The Audi A3 8P with a 2.0 TSI (EA113) engine with a factory power of 200 HP is a classic in the hot hatch segment.
The unit with direct fuel injection and a K03 turbocharger already offers good performance in series, but its true potential is revealed only after modifying the MED9.1 controller software .

This ECU offers enormous tuning possibilities – both for workshops and tuners cooperating in the file service model.

What can you get from the Audi A3 2.0 TSI (MED9.1)?

The Bosch MED9.1 controller enables precise tuning of the ignition, boost pressure, torque and fuel maps.
Without replacing components, within a safe range, you can achieve:

The result is a noticeable difference in throttle response, elasticity and acceleration – the car handles lighter, more aggressively and responds more smoothly to any load change.

MED9.1 file processing – professional file service for tuners

For workshops and tuners, we offer ready-made chip tuning files and individual processing of ECU files .
Each file undergoes a verification process on Dynomax / Dynomet dynamometers, and modifications are made manually, without the use of ready-made "drivers".

Thanks to this:

• 💾 Each Stage 1 MED9.1 file has optimized torque, boost and AFR maps,

• ⚙️ We maintain the safety margin of the turbocharger and EGT,

• 🔍 Each software is tested in real conditions, not only in theory,
