Engine remapping in Lausanne

stage 1 remapping.

Stage 1 consists of an engine management remapping without requiring any additional mechanical parts. It is designed to combine reliability with high‑level performance.

Stage 2 combines a performance‑oriented remapping with hardware modifications. On diesel engines, it includes disabling the EGR valve and the particulate filter (DPF). On petrol engines, it includes exhaust line modification and catalyst removal.

gearbox remapping.

Gearbox remapping significantly improves the speed and smoothness of gear changes. Depending on the chosen stage (stage 1 or stage 2), shift times are reduced by 20 to 30%, offering a more dynamic and responsive driving experience. It also increases the torque limiter, enhancing overall vehicle performance. By increasing clutch pressure, gearbox durability is improved, ensuring a more reliable and efficient transmission.

start & stop OFF

At times, the automatic start‑stop system can be intrusive. When restarting, it may become uncomfortable. This option disables the feature completely.

vMax OFF

This function increases or completely removes the vehicle’s maximum speed limiter.

SCR AdBlue OFF

When the AdBlue system malfunctions, a warning light and a mileage countdown appear on the dashboard. The vehicle enters limp mode and cannot be restarted once the countdown reaches zero. This option disables the system entirely.

EGR OFF

Electronic deactivation of the EGR valve. This option blocks the valve to prevent exhaust gas recirculation.

GPF DPF OFF

Electronic removal of the particulate filter on diesel engines.

CAT (decat) OFF

Electronic removal of the catalytic converter on petrol engines.

COD OFF

COD (Cylinder Deactivation) is a technology that deactivates certain cylinders when they are not needed, such as during steady‑speed driving. This can improve fuel efficiency. This option disables COD.

CS (cold start) OFF

This option disables the cold start function.

swirl flap OFF

Deactivation of swirl flaps, a system that creates airflow turbulence in the intake manifold.

sport display

On BMW vehicles, this option adjusts the sport display according to the vehicle’s new performance.

exhaust flaps

The “exhaust flaps” option opens the valves to 100% when the vehicle is in sport mode.

pop & bang

“Pop and bang” is generated by ignition retardation, causing exhaust detonations when lifting off the throttle. This should only be applied on vehicles equipped with a sport catalyst or bypass.

DSG farts

On DSG gearboxes, “farts” are small pops heard during gear shifts. Not all sports cars have this feature. This option enables the “farts”.

launch control

This improves take‑offs by keeping the engine at its optimal RPM. Launch Control maintains a specific engine speed when the clutch pedal is pressed.

E85 Flex Fuel

This option enables ethanol conversion.
