VEHICLE ECU TUNING

Vehicle ECU Remapping and Performance Tuning is for people looking to improve the performance of their vehicles without undertaking massive upgrades.

Our new facility enables us to replace the software that’s used in the your vehicle ECU system (the engine management controller). It’s this software that determines how your vehicle performs and the output from the engine. Often this software is generic to all vehicle models regardless of country and regional variances in regulations – meaning a UK vehicle maybe be restricted by Swedish or German emissions or other regulations.

Any vehicle

The ECU upgrades are available for most vehicle manufacturers and models (including performance vehicle). They consist of a fully customised and tested replacement piece of software that is loaded into the ECU of your vehicle. Once installed the benefits will immediately become apparent in the vehicle.

Commercial vehicles including VAN’s will see an improvement and anyone using their van for regularly carrying heavy loads will see a benefit from the improved torque available. We have also performed the upgrade on MOTORHOMES where the improved torque makes for a more relaxed drive and reduced engine noise. These benefits come at little cost with often an improved fuel consumption.

Possible improvements

Following an ECU remap you will immediately see the benefits of between 15 – 20% BHP increase together with an increase in torque – we can tell you the actual increase before the upgrade is performed and have included the figures for the most popular vehicles on our ECU performance page.

So why should I remap my ECU? 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. Areas such as climate, emissions, fuel quality etc all have to be considered by the manufacturer. What this means is that a vehicle ECU is never optimised for one individual situation.

So how can a reputable ECU remapping company help? They will actually read your own engine’s map file, modify it and then upload it back to the ECU. The company should always take the time to find out your own individual requirements and what you want to achieve from a remap. They will then tailor the map to suit before it is uploaded back to the 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 (chipped). 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 flexibility throughout the rev range, allowing for smoother acceleration and better overtaking.

Beware of cheap imitations… There are many companies out there offering what seem like value for money ECU remapping services. Most of these companies use stock files (maps) that are cheaply available through the internet or other sources and are NOT tailored to your own individual requirements. These can actually damage your engine as they are not specific to your vehicle.

Before remapping your ECU any reputable company should carry out a full diagnostics check of your engine and advise you accordingly if there are any potential problems or components that need replacing. Please be aware that, although remapping/chipping an ECU does not cause failure it can exasperate already failing components. In order to assure a quality ECU remapping service the company of choice should not carry out work on any engine that is found to be faulty without written consent from the owner. If they ignore faults shown up by the diagnostic process, then make your excuses and politely leave their premises.

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 10 – 15% 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 25 – 50% power (bhp) and around a 50 – 75% 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.
