About the high-performance large-displacement petrol engine (V8, V10, V12, W12, AMG, RS)
This group covers the large-displacement, mostly twin-turbo or supercharged petrol engines of Mercedes-AMG, Audi RS/S, Bentley, Porsche, Maserati, McLaren and similar brands. They make high power from the factory and are managed with tight temperature, knock and torque limits.
How a Stage 1 remap works on the Audi S8 4.0 TFSI Plus 605hp
A Stage 1 remap looks at torque request, boost pressure, ignition and gearbox torque limits together. Gains are clear on twin-turbo engines; on large naturally aspirated engines the effect of software is more limited. Cooling and gearbox limits are kept.
Pre-remap checklist
- Spark plugs, coils and fuel quality (high octane recommended).
- Cooling system and intercooler efficiency.
- Gearbox torque capacity and oil condition.
- Fault memory and any previous software or hardware changes.
On these engines the result depends heavily on hardware and fuel; figures are confirmed by measurement.
This section is based on Prime Chiptuning workshop experience; the power and torque figures come from the catalogue measurement above.
