Intake Manifold Flap Removal

Intake Manifold Runner Flaps, sometimes known as tumble flaps or swirl flaps, allow an engine to better mix the fuel and air charge into the cylinder to aid power and torque. Unfortunately fowling of intake manifold flaps is common due to intake carbon deposits. This can cause the intake manifold flaps to become stuck, often physically failing. Additionally failed position sensors or actuators can cause intake runner flap faults.

When most engine control units (ECUs) detect faults with the intake flap operation they will display an engine fault light on the dashboard and often place the car in a reduced power 'limp home' mode.

These flap systems can be costly to replace, with some manufacturers only supplying complete intake manifolds with runner flaps built in.

The ByteFLASH intake flap removal software patch allows the intake manifold flaps to be removed, along with removal of the position sensors and actuators. The Engine ECU is re-programmed to operate without these sensors or actuators connected and without any limp mode or warning lights.

UK Law

If you are located outside of the UK, please check your local laws. For UK customers and installers, Under the Road Vehicles (Construction and Use) Regulations and the Road Traffic Act 1988 it is an offence to use on a road a vehicle which has been modified in such a way that it no longer complies with the air pollutant emissions standards it was originally designed to meet. Removal of emissions control devices is intended to support motorsport and off-road applications. Further information on the UK law can be found on the UK government website here.
