UroTuning is excited to announce that Unitronic Stage 1+ E85 and Stage 2 Performance Software is available now for the 2.5TSFI enignes found in the 2017-2018 Audi RS3 and 2018 Audi TTRS! These exciting new ECU calibrations build on current offerings and are compatible with UniCONNECT+, allowing users to tune directly through the OBD-2 port right at home!
Stage 1 and Stage 1+ tunes include features like a spark-based motorsport-style rev limiter, with left foot braking enabled, allowing the driver to build boost while braking, as well as Dynamic / S-mode allowing both exhaust flaps to be alway open. The new stage 2 tune from Unitronic also incorporates new features for "street" and "drag" traction files, allowing the user to compensate for varying surfaces and tires.
