ECU tuning or Chip tuning simply remaps and alters the parameters set on your vehicles ECU (engine control unit). Delivering improved and increased power and efficiencies.
Our remaps are carried out via the diagnostic OBD2 Socket, or direct into the ECU using specialised adaptors.
What is an ECU?
All modern cars and vans have an ECU (engine control unit). This Engine Control Unit is basically the vehicles ‘brain’. It contains a processor that takes information from various sensors throughout the engine, it then analyses this information such as, accelerator pedal angle, the engine temperature, oxygen content as well as many other parameters. Using this information it can then add the right quantity of fuel, at just the right time to provide a good mix of fuel economy, performance and emission control when pulling away, overtaking, or powering down the motorway.
What are the benefits of ECU Remapping?
Most cars equipped with an engine management system can be tuned, including both petrol and diesel engines. Chip tuning or remapping produces best results on turbocharged, or supercharged engines. Raising the turbocharger or supercharger boost pressure, allows for much higher gains in power to be achieved, when combined with the correct ignition timing and fuelling adjustments.
Non-turbo engines will gain a significant improvement in power where the manufacturer also offers the same engine in a significantly detuned state by ECU software alone.
With a remapped car you will benefit from:
- A more responsive engine
- Improved fuel consumption by an average of up to 20%
- Smoother power delivery with fewer gear changes
- Improved acceleration for safer overtaking
