PERFORMANCE TUNING SERVICES

Remapping is a software change where we modify the operating parameters in the vehicles ECU program or ‘map’. We do not change or add any hardware in your vehicle. In many cases the map stored on the ECU’s processor can be accessed via the on-board diagnostics port (OBD) in the vehicle, normally found under the dashboard. In some newer models the ECU will have to be removed from the vehicle and programmed on the bench.

Once one of our IMI professionally qualified technicians have read the vehicle they will upload the original map to the file writing team. During the mapping process they will adjust the parameters to maximise the performance, fuel economy, or a clever blend of both. Depending on the vehicle and ECU type the remapping process normally takes less than an hour, sometime longer if it needs to be programmed on the bench.

Performance Package Icon 1

SR Green

Designed to return an improved economy in turbo diesel engines. By re-characterising the torque limits on the engine, at lower rpm’s you will benefit from additional performance and improved economy.

At higher rpm’s the software will encourage shifting up through the gearbox, to keep the engine running in its optimal window.

SR Blue

The most popular remap choice, offering the best mix of power and economy in virtually all turbo diesel engines. Designed to de-restrict the engine and open up the true torque and power range.

Swallows Blue offers a better driving experience while returning an improved fuel consumption figure. Parameters are carefully managed to optimise best burn times and achieve optimum pressures.

Performance Package Icon 3

SR Red

High Power & Ultimate Performance Designed to fully unleash the full potential of your engine. By enabling the power delivery to come late in the rev range the power is then in the optimum position for spirited driving on roads or track.

Swallows Red is recommended for use with petrol engines only and is specifically designed for performance only.

SR STAGE ONE PERFORMANCE PACKAGE
