A vehicle remap replaces default software on the ECU, overwriting it with new software which can be programmed to optimize the cars overall performance. This is known as vehicle remapping because the ECU is essentially a program that controls how the engine works. When your car is remapped, the tuned software is plugged into your cars serial port (or OBD port) which then overwrites the engine map with the new version to enhance engine performance. The ability to flash directly through the OBD has brought the tuning industry on leaps and bounds, with constant development on the engine now being much quicker via the flash process; it has enabled us to develop some of the best software in the world.
Many people say that ECU remapping doesn’t affect fuel usage; however this is not technically true. Because of the process involved in ECU remapping more fuel is going to be consumed in order to produce the increase in power. If the car is driven in an enthusiastic way after the remap has been carried out then the fuel economy will not increase (and in some cases may decreases). If, however, the driver modifies their driving style to make the most of the increased power and torque throughout the rev range then fuel economy can be increased. A good example of this could be that the improvement in torque produced by the engine after remapping means the driver no longer has to drop down a gear to maintain speed on an incline or may not have to change gear as frequently in traffic. All of these little things add up to an improvement in fuel economy.
There are many reasons to choose vehicle remapping. Firstly, you will notice that your engine responds better when the accelerator is pressed. The overall torque and power will be noticeably increased. Power delivery will be smoother making for a much safer driving experience, which in turn also makes it easier and safer to overtake. During normal driving you will notice that your MPG is better which not only decreases the cost of fuel that you will have to pay, but it also minimises your carbon foot print. Throttle response will be improved and the rev range will be enhanced.
Manufacturers supply their vehicles all over the world, so have to tune the engine management system so that the car can operate wherever it ends up. So it it de-tuned to cope with the worst case scenarios. Also some manufacturers already do offer the same engine in various states of performance.
No one can say for 100% certainty that the remap will be undetectable. However, the modification to the software will not show up on any main dealer diagnostic equipment and therefore unless you tell them that it has been done, they will be none the wiser.
Depending on what your requirements are and your driving style depends on what your fuel economy will be. If you go for an outright maximum power output and drive it as so, you can expect to see it decrease as it would without the map. If you get the map to increase torque low down and drive conservatively then it is likely that fuel economy will increase. Please note that fuel economy gains are only likely on turbo diesel engines, petrol engines generally stay the same with some reporting slight improvements, never a loss.
The beauty of the remap is that this process is completely reversible without any trace; therefore if within 28 days you want it changed back, we will carry it out free of charge. If after 28 days you wish to reverse it then there is a £50 charge for the process.
This is up to you. We have to advise that you inform your insurance companies that the remap has been carried out but as there is no way for them to read this map, it is up to you what you do. It is your responsibility.
Existing modifications can sometimes bring good benefit to enhancing the software so let us know in advance.
Again, let us know what you’re planning so we can advise the best way forward and can even offer great package deals on other performance upgrades.
