We are often asked why vehicle manufacturers don't remap their engines before they leave the factory. This point is important when considering ECU tuning for your vehicle, and there are 5 main reasons for this.

NEW RELEASES


First of all, selling new vehicles with untuned engines allows the manufacturers to release new models several months later at a higher price. Although these models have identical engines, they can make them produce increased power, better fuel economy and lower CO2 emissions after a simple ECU remap. This allows them to charge more money for a vehicle that is identical to the previous model!




INTERNATIONAL DIFFERENCES


Secondly, new cars are sold to various countries all across the globe and so the engines aren't tuned as they would struggle to run on the sub-standard fuels in some less developed areas. In addition, manufacturers have to make substantial compromises to a vehicles performance so that they can function in climates with extreme temperatures, humidity and operating altitudes. However, in the United Kingdom we are not affected by any of these and so we can safely enchance the engines performace without putting the vehicle at any increased risk.




CARELESS OWNERS


In addition, having an untuned engine allows for engines to run for longer for drivers who don't adhere to service schedules and who don't look after their vehicle by checking oil levels and engine coolant, for example. If the vehicle is looked after and serviced when required there will be no problems!




INTERNATIONAL REGULATION


All new cars in some countries must have a dip in power between 2000-3000 RPM by law in order to reduce emissions. However, this particular regulation doesn't apply to vehicles once they have left the factory.




COST CUTTING


Finally, tuning an engine adds unneccesary time and cost to the production of new vehicles.
