Frequently Asked Questions
What does an ECU remap do on the Audi Q7 4.2 TDI 326hp ( 326 PS / 240 kW )?
An ECU remap (chiptuning) modifies the engine control unit software to optimise parameters like injection timing, turbo boost pressure and fuel delivery. On the 4.2 TDI 326hp ( 326 PS / 240 kW ), this typically results in more power, better throttle response and improved fuel efficiency at part load.
How much power gain is possible with Stage 1 on the 4.2 TDI 326hp ( 326 PS / 240 kW )?
Stage 1 brings the 4.2 TDI 326hp ( 326 PS / 240 kW ) from 326 PS to 375 PS — a gain of +49 PS. No hardware modifications are required, making it the most popular and cost-effective tuning option.
