Let's say you want to drive a car with more power or a van that travels farther on a tank of fuel. You could head to the nearest dealership and check out the latest Audi, BMW, or Mercedes vehicles. Or you could take one very simple step to improve the car you already have. Remapping the engine control unit (ECU) is an increasingly popular option for drivers who want to upgrade their vehicles at a reasonable cost.

The ECU, or engine control unit, contains many different maps (programmes) that control all aspects of fuel combustion and engine operation. Remapping the ECU involves modifying the maps -- carefully, with great precision -- to get more power from the engine and optimise vehicle performance.

But where does the additional power come from? The funny thing is, it's been in the engine all along. Car makers routinely tune their engines to limit power output Autel MaxiSys. One reason for this is to ensure that their vehicles will run reliably in extreme climates and in places where fuel quality is poor autel online.

Limiting engine power also has certain commercial advantages for car makers. For instance, they can offer buyers an entry level model with a moderately powered engine. Then they can tune the engine for higher BHP and torque and sell the very same car as a more expensive upgraded model. A little bit sneaky -- but you can do the same thing. You can tune the engine in your own car for more power, just by remapping the ECU.

A good ECU remap is completely customized to your vehicle, the type of driver you are, and the benefits you want to gain. More power, more torque, and improved fuel economy are to be expected from any remap. But you can often choose which benefit is more important to you and the technician will tune the new maps accordingly.

For example, some drivers want maximum performance above everything else. The ECU can be remapped to increase power and torque in the upper-mid range where it's needed most. Throttle response becomes sharper and acceleration is smoother, which allows for assertive vehicle handling and safer overtaking on highways. This type of remap can increase engine power by up to 35%, depending on the model of car.

Other drivers are more interested in easier driving, lower fuel bills, and reduced CO2 emissions. Remapping for fuel economy involves tuning the engine for more low-down torque. This reduces the gear changes needed in everyday city driving, which in turn can lower fuel consumption and emissions. With this type of remap, drivers can see fuel savings of up to 20%.

Turbo diesel-powered engines will typically see the most dramatic improvement from an ECU remap. If your car has a turbo petrol engine or a normally aspirated engine, there is less potential for improvement but you can still obtain significant power gains from a remap. Don't hesitate to call up the service provider and ask what they can do for your particular vehicle.

Remapping the ECU on modern cars is safer and easier than ever before. The technician doing the work doesn't need to remove the engine control unit or tamper with any internal parts. Instead, the engine control unit is remapped via the On Board Diagnostic port, using the latest software and equipment. The car's original map is downloaded to the technician's portable computer, rewritten to the desired specs, and then flashed back to the ECU. A copy of the original map is saved, so you can return the engine to its prior tuning state at any point in the future.

Settings for turbo pressure, turbo threshold, turbo limiters, turbo injection control, fuel injection, RPM load, and many more factors are optimised during the remapping process. The technician must make sure to stay in the green zone when tuning the maps; that is, work within the tolerance limits of the vehicle. After the remap, you'll immediately notice extra power and better response from your car.

A properly done ECU remap can boost power and make driving more fun without harming your car in any way. Just think about the superb engineering that goes into modern vehicles -- it's almost a pity not to take full advantage, wouldn't you say? Remapping the engine control unit is a vehicle modification that can quickly turn your good car into a great one.
