For the past several months, our engineers have meticulously tested and tuned the new 2.5 TFSI found in the Audi RS3 Sedan and TTRS. This has included hundreds of dyno pulls, over 40 passes at the drag strip and more than 50 laps around Road Atlanta. You can read more about our testing and instrumentation here: APR RS3 Sedan Testing and Tuning Update!
We visited our local drag strip, Montgomery Motorsport Park, to test the factory software vs our development software for the 2.5 TFSI found in our RS3 Sedan. In terms of engine / performance hardware, we tested our software only, leaving items such as the intake, exhaust, intercooler, fueling and more completely stock. The vehicle was equipped with Toyo R888 tires for added grip. Please Note: Date/Time stamps are 55 minutes ahead of the actual time.
First, we ran the stock tune on 93 octane, full weight (DA: ~600 FT):
Next, we flashed the ECU to our development Stage 1 tune on 93 octane, full weight (DA ~800 FT):
The 2.5 TFSI found in the brand new TTRS and facelifted RS3 sedan is a totally new 5-cylinder engine from Audi including an all new version of Bosch’s MED17.1.62 engine management system. The engine differs from other 5 cylinders in the past, using a brand new turbo, with a new control strategy, new dual injection system and new engine block material among other changes. We’re in uncharted territories tuning this new amazing platform!
With any new project that vastly differs from others in the past, our engineers take a cautious and thorough approach to tuning the engine. This starts with data collection. Our APR ECU Explorer logging tool give us direct access to the entire ECU. That means we can read every sensor within the engine bay, and every single calculation taking place within the ECU, at extremely high data rates. This data resolution is second to none, leaving our tuners with the ability to see everything as it happens, with the ability to trace back to why it happened within the ECU. This allows our engineers to understand the ECU algorithms and strategies better than the competition. This is contrary to others relying on OBDII diagnostic channels, which gives poor …
