Info: Krasser exhaust sound via fuel cut

Reprogramming of fuel cutoff is a popular tuning process. The overrun fuel cutoff is a procedure that should result in a momentary fuel cut. The method is used selectively in an internal combustion engine. The engine should no longer deliver power and be towed by the remaining momentum. An overrun fuel cutoff has been standard equipment in internal combustion engines for decades. The procedure for the temporary interruption of the fuel supply was first used in diesels and later used in gasoline engines.

Fuel cut can increase engine efficiency

Fuel cut-off can reduce fuel consumption and CO2 emissions. At the same time, engine efficiency can be increased. The fuel supply is completely cut off when the engine is in overrun mode, the vehicle user does not accelerate and the engine speed is above idle speed. The engine only continues to run through thrust and works completely without emissions. In this case, the thrust is the mass inertia and the low consumption caused by the overrun cut-off can be read on the consumption display. In addition to fuel cut-off, some automatic transmissions have one sailing modewhich automatically switches to idle. The sail mode should again not be confused with the fuel cut. If the engine speed drops in the direction of the idling speed during overrun, then fuel is returned to keep the engine running. When exhausted, there are no exhaust gases, but no exhaust gas sound is heard.

Programming the fuel cut in the tuning range

The fuel cut-off can be reprogrammed so that the fuel supply is not interrupted. The fuel cut-off is not completely deactivated when reprogramming. The shutdown is shifted backwards. As a result of the programming of the fuel cut-off, you can Misfires be generated. At the same time one can Bubble generated in the exhaust system. The exhaust sound is retained by reprogramming the fuel cutoff.

Reprogramming the fuel cut-off is a complex undertaking and should only be carried out by professionals. In some forums it is said that programming is done with VCDS. For the functional reprogramming of the overrun fuel cutoff, however, a complete re-tuning of the engine control is required. The motor control is re-tuned in overrun mode. In Germany there are workshops that offer, for example, the deactivation of the overrun fuel cut-off together with a core field optimization. We would like to mention here, for example, under partner companies Special Concepts.

When choosing the right tuning workshop to re-program the overrun fuel cutoff, it is essential to pay attention to modern and professional know-how. And finally ... The overrun fuel cut-off is fitted as standard in combustion engines and ensures reduced CO2 emissions. At the same time fuel is saved and the engine runs on for a short time without fuel injection. If the fuel cut is in operation, then no exhaust noise is heard. By reprogramming the overrun fuel cutoff, for example, the desired tuning sound can be retained and the fuel cutoff can be shifted to the rear. However, it is advisable to have such reprogramming done by a professional. This can safely carry out the complex process and immediately make a re-adjustment of the engine control. Only VCDS should not be used to program overrun fuel cutoff.
