WHAT IS ECU (ENGINE CONTROL UNIT)?
All modern cars and vans on the road today have an ECU (ENGINE CONTROL UNIT). This Engine Control Unit can almost be described as the vehicles ‘brain’ and contains a small processor that takes information from various sensors throughout the engine. It analyses information such as the engine temperature, accelerator pedal angle, oxygen content in the burnt exhaust gases as well as many more parameters. Using the information from these sensors 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, pottering down the road or zooming down the motorway.
