Audi RS3 ECU remapping
425 files available
About remapping
The Audi RS3 accounts for 425 files in our catalogue, almost entirely the 2.5 TFSI five-cylinder — one of the most celebrated turbocharged petrol engines in the modern market, covering the 340, 367 and 400 hp variants. It is a compact performance car with a devoted following.
The split is striking: 231 Stage 1 files against 160 Stage 2, plus 25 pop and bang. It reflects how many of these cars arrive with hardware already fitted. The ECUs include MED17.1.62, MED17.1.1, MED17.1.6, MED9.1 and MED9.1.2, plus DQ500 transmission units.

How much does the 2.5 TFSI take?
It is one of the most celebrated turbocharged petrol engines on the market, with genuine headroom. That is precisely why so many owners go beyond Stage 1.
What is the DQ500?
It is the dual-clutch transmission ECU. Work on it adjusts shift points and torque limits, and often complements an engine map on a car with this much torque.
Why so much Stage 2 work?
Because a large share of these cars arrive with intake, exhaust or intercooler modifications already fitted. If your car is standard, Stage 1 applies.
