Mercedes-Benz CLS Shooting Brake 500 BlueEFFICIENCY 4MATIC Automat - 408 HP

Automatic transmission shift optimization

Optimizing the shift strategy of an automatic transmission brings smoother driving, faster throttle response and better use of engine power. The gearbox shifts at ideal RPM so the engine is not unnecessarily lugged, which improves comfort in everyday driving as well as acceleration dynamics. The modification can also reduce unnecessary downshifts and repeated searching for the right gear.

Speed limiter disable

Is the top speed limiter preventing you from using the car's full performance potential? We offer its deactivation so the vehicle can reach its true maximum potential without artificial restriction.

Lambda sensor disable

Do you use a sports exhaust where installing a lambda sensor is not possible, or are you dealing with lambda sensor faults and error messages? We offer a software lambda disable that ensures stable engine operation without unwanted limitations.

Disabling the lambda sensor limits closed-loop combustion control, which may affect fuel consumption, emissions and engine management precision. This modification is mainly intended for modified vehicles and is not suitable for regular road use.

Secondary air injection disable (SAP)

Software deactivation of the secondary air injection system removes faults related to a defective SAP valve or pump and prevents diagnostic errors from returning after the system has been mechanically disconnected.

Service availability is verified for the specific control unit.

Readiness calibration of emission monitors

Readiness calibration adjusts the status of individual OBD monitors so that diagnostic tests can be completed correctly. In practice, it can help bypass emissions inspection issues, for example when the vehicle has a fault or a modified emissions system.

This modification interferes with the vehicle's emission diagnostic systems and may conflict with legal requirements. A vehicle with this modification may not meet the conditions for road use.

Burbles / Crackles activation

By modifying the ECU, we activate the so-called burbles / crackles effect, which creates characteristic popping and crackling from the exhaust when lifting off the throttle or downshifting. This effect is typical for sporty and high-performance vehicles and gives the car a more emotional and pronounced sound character.

This modification increases the thermal load on the exhaust system (especially the catalytic converter and turbocharger) and may lead to faster wear or damage. It is not suitable for long-term normal road use or stock vehicles without additional modifications.

EVAP system disable

The EVAP system captures and re-burns fuel vapors from the tank, thereby reducing emissions. In practice, however, it may cause fault messages, unstable idle or issues after fuel system modifications. By disabling it, we ensure more stable engine operation without unwanted interventions and recurring errors.

Disabling the EVAP system leads to increased emissions and may allow fuel vapors to escape into the surroundings.
