Remapping or chipping your engine is usually carried out to boost performance and improve fuel economy, but it can also cause some problems. The amount of power you can squeeze out of your car is not limited by how far you can get your pedal down but by your car’s ECU or engine control unit and the software it is running.
The results can be dramatic – for only a few hundred pounds you can apparently take the power output of a Mk6 Volkswagen Golf Gti from its factory setting of 207bhp and 280Nm of torque to 251bhp and 324Nm of torque. In a turbodiesel a remap can improve fuel economy by up to 10 per cent by increasing lower range torque.
Buying a remap from a reputable company shouldn’t cause your car any mechanical problems as the software is carefully developed to ensure that it doesn’t exceed the acceptable parameters of your engine’s capabilities. Essentially, remapping is quite often what manufacturers do when they release a higher performance version of an existing model rather than develop a new engine every time. Earlier models have usually been limited with respect to performance, and those limits are simply raised for subsequent models in order to offer extra power.
WHAT ARE THE EFFECTS OF ECU REMAPPING?
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.
HOW WILL REMAPPING AFFECT MY FUEL CONSUMPTION?
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.
CAN THE REMAP BE REVERSED?
The beauty of the remap is that this process is completely reversible without any trace; therefore if within 14 days you want it changed back, we will carry it out free of charge with a full refund. If after 14 days you wish to reverse it then there is a £50 call out charge for the process but no refund will be given unless otherwise agreed prior to the 14 days elapsing.
HOW MUCH WILL THE REMAP COST?
Most of our remaps cost £250+VAT, however every vehicle and engine variant differs so please contact us by telephoning 01752 256 688 or emailing email@example.com for a full detailed quote.
I HAVE EXISTING MODIFIACTIONS, WILL THIS AFFECT THE REMAP?
Existing modifications can sometimes bring good benefit to enhancing the software so let us know in advance.
