Not sure which engine you have?

The badge alone is not enough: in this generation, the same engine designation came in different power outputs, each with its own calibration. Check the power output in your registration document and find the matching row.

More power and torque without rewriting the ECU or swapping any parts. The GAN box only adjusts the engine sensor signals. Your manufacturer’s warranty is preserved: the ECU software is never changed, and the box can be removed at any time.

FAQs

Audi S8 D2 remap: common questions

Which tuning box do I need for the Audi S8 D2?

Every engine in this generation is naturally aspirated, so it takes the GAN GA or GAN GA+. Find your engine in the table above – each row shows the box and its price.

Is a tuning module the same as a Stage 1 remap?

Not quite. Stage 1 usually means an ECU remap without replacing any parts. The tuning module also works without replacing parts, but it does not change the ECU software: it adjusts the sensor signals, comes off in about a minute, and the OFF button in the app restores the factory settings.
