So, what is it and why do it?

ECU remapping involves fine tuning the parameters control your engines performance. Most reputable companies use bespoke maps that are tailored to your car and your own individual requirements.

Today's modern engines rely heavily on computer controlled engine management systems. Each engine has an array of sensors which monitor readings such as throttle position, crank position, airflow etc. These signals are sent to the Engine Control Unit (ECU), which processes the information received to control parameters which affect the output of your engine.

When vehicles are distributed throughout the world, manufacturers adopt a one map fits all policy. This one map has to take into account many different factors that are necessary for each export country ie;  climate, emissions, fuel quality etc all have to be considered by the manufacturer. What this means is that a vehicles ECU is never optimised for one individual situation or location.

So how can a reputable ECU remapping company help?

We will read your own ecu's data, modify it according to your requirements and then install it back onto your ECU. By remapping your ECU it is easily possible to release extra power and torque from your engine without any reliability issues. Many owners also report that they have seen improved fuel economy once their engine has been remapped. Be aware that although many customers experience improved fuel economy, this depends on your own driving style and how heavy your right foot is.

The increase in power and torque that is gained using ECU remapping provides a much smoother drive, with increased power throughout the range, allowing for smoother acceleration and better overtaking.

What kind of improvements can I expect?

As mentioned you will notice an improvement in power and torque right throughout the rev range, along with the possibility of improved fuel economy. See below for a general idea of average improvements for different engine types:

Petrol (non-turbo) - By remapping a normally aspirated engine ECU, you would normally expect to see a 8 - 10% increase in power (bhp) depending on your exact engine specification, and around a 15 - 20% increase in torque (Nm) throughout the rev range. This improves engine response on a lighter throttle.

Petrol (turbo) - By installing a modified engine ECU map on to a turbo engine you would normally expect to achieve around a 20 - 30% increase in power (bhp), with an increase in torque of around 20 - 40% depending on your engine specification. The large increases in both power and torque will greatly improve the engine flexibility in all gears and throughout the rev range.

Diesel (turbo) - Remapping a diesel turbo ECU normally sees the greatest gains of any engine type. Typically you will achieve an increase of 15 - 35% power (bhp) and around a 30 - 50% increase in torque depending on your engine specification. The engine response is greatly improved throughout the whole rev range and in all gears. Diesel engines are well known for providing huge amounts of torque and in gear performance. A remapped modern turbo diesel engine has the ability to embarrass many petrol engine cars under normal driving conditions.
