Audi RS5 B10

We deliberately took the far more demanding route of reprogramming the engine and HCP1 control units. That is the only way to keep drivability at manufacturer level with significantly increased power.

We deliberately decided against add-on control units that manipulate the pressure sensors, because the engine torque delivered at full load stays at the original value and a number of drawbacks have to be accepted as a result:

• Power yield too low
• The transmission unlearns its adaptations, causing higher wear and poor shifts
• Ignition and injection cannot be adapted, leaving no safety reserves.
