Here you will find some technical information on remapping with the history of the related parts and processes that are involved. If this sounds too boring for you then why not head on over to our services page to get a brief overview of the services and products we offer. For the rest of you, here we go……
During the early 80’s vehicle technology changed dramatically with the implementation of computer technology. ECU’s (electronic control units) were introduced into vehicles in order to improve performance and efficiency. In the early days ECU’s controlled just a handful of processes, with advances in both electronic and computer technology ECU’s now control a vast amount of electronic and mechanical processes. Signals transmitted from sensors located on the engine and chassis provide vital information to the ECU so that real time adjustments can be made. Engine speed, boost pressure, fuel pressure, cam timing, lambda and pedal position are just a few examples of the parameters measured by an ECU and the parameters it can control.
Like your home PC has software (drivers) which controls the computer hardware (CD drive, Speakers. etc.) an ECU also has a piece of ‘software’ or program loaded onto it which controls the hardware components of an engine, this program is often referred to as a map. Although a map file extracted from an ECU will actually contain several maps. E.g. Boost Map, Fuel Pressure Map, Injection Quantity Map, lambda Map, etc…
By extracting the map data from the ECU, the individual maps can be modified and reloaded to the ECU. If these maps are recalibrated correctly, the performance, drivability and efficiency of an engine can be improved. This process is called Remapping.
In most cases the performance of a vehicle with factory settings is so far away from the engines true potential performance it could be said that they are electronically detuned by the manufacturers. Sounds crazy? I know, but there are several significant reasons for detuning a vehicle and it will become clearer as you read on.
