Bespoke ECU tuning.

Tailor-made map optimisation

Depending on the engine and ECU, we fine-tune torque request, boost pressure, ignition and injection to work together, among other parameters. Technical condition, fuel quality and intended use all feed into the development.

Whether stock or modified hardware: changes to the intake, charge-air cooling, exhaust system or turbocharger are taken into account in the calibration. The aim is controllable power delivery across a usable rev range.

Component protection included

More power also means higher loads. That is why we respect the thermal and mechanical limits of the engine, turbocharger, gearbox and cooling system. Functions relevant to component protection remain active.

We ensure a controlled build-up of torque and respect the reserves of the components fitted. A good state of maintenance and the right fuel quality are the foundation of every optimisation.

Verified on the all-wheel-drive dyno

On our all-wheel-drive dyno we check the power and torque development and assess the relevant operating data. This allows us to verify the calibration precisely and adjust it where necessary. Besides peak power, we look at the torque curve, throttle response and behaviour under load. The result is documented transparently.

SMNProtect – our own guarantee

On request, you can add SMNProtect, our own guarantee programme, to your performance upgrade – even for a pure software map optimisation without additional hardware.

Within the agreed guarantee terms, the cover also includes damage to the engine and drivetrain that is demonstrably caused by the performance upgrade we carried out. Your direct contact is SMN83 GmbH.

We advise you in advance on the right package. Scope, term, requirements and exclusions depend on the package chosen and the applicable guarantee terms. Vehicle age and mileage are taken into account.
