Remapping as a software change where we modify the operating parameters in the vehicles ECU program or ‘map’. We do not change or add any hardware in your vehicle. In many cases the map stored on the ECU’s processor can be accessed via the on-board diagnostics port (OBD) in the vehicle, normally found under the dashboard. In some newer models the ECU will have to be removed from the vehicle and programmed on the bench. We have read the vehicle we will upload the original map to our file writing team. During the mapping process they will adjust the parameters to maximise the performance, fuel economy, or a clever blend of both. Depending on the vehicle and ECU type the remapping process normally takes less than an hour, sometime longer if it need to be programmed on the bench. Our tuning partner works to the highest standards in all aspects of our operation and this includes our business ethics, so therefore you can be assured that:
  • We will not overstate our figures to make them appear better than our competitors
  • We will not quibble over our 30-day money back guarantee
  • We will not raise your expectation of fuel savings, to a unreasonable level
  • We will tell you if the improvements on your car are minimal and therefore not worth doing
  • We will never pass on or sell our customer data

Our Services


ECU REMAPPING is when we take a read from the ECU’s processing chip of the vehicles standard tuning map. We then adjust various parameters within the map such as fuel pressure, boost pressure (on turbocharged applications) ignition advance and throttle pedal control, amongst others to release the true performance from the engine. When a manufacturer develops a new vehicle they take into consideration all driving conditions and regions in which they intend to sell this model, in other words the tuning is a compromise. We rewrite or remap the vehicles engine software to safely gain more power and torque. This gives improved drivability and the added bonus of enhanced fuel economy on diesel engines.


Here at Swansea Tuning, we have a very advanced Solution for EGR. The valves can become clogged with carbon deposits, causing them to fail or stick, thereby causing error codes and the vehicle not to run correctly. Our software solution to disable the EGR valve is a simple and effective method of improving the efficiency of your engine. Our EGR closed or banking solution and reprogramming of the engine management ECU results in lowered engine temperatures, improved throttle response and economy and also can lengthen engine life by reducing oil contamination and carbon deposits. See our information on Carbon Cleaning.


Our ECONOMY REMAPPING works by improving the efficiency and power of the engine to make the engine work less hard, in any given situation. Reduced throttle load and the ability to be in higher gears sooner and for longer results in marked fuel efficiency gains. Customers will see FUEL IMPROVEMENTS of typically 8-10% on most diesel vehicles, often more when opting for our Green remap. Great for fleets too where the savings really count.


CHIP TUNING is simply remapping by another name, but involves the physical removal of the program chip from the main ECU in the vehicle and either re-programming or replacement with a new chip modified with a remap. Technology developments mean that Chip Tuning is rarer now, but is still the only way to programme certain vehicles. Nowadays most remaps are carried out via the diagnostic OBD2 Socket, or direct into the ECU using special adaptors on the bench


There are three phrases which often used interchangeably. These are: 'OBD TUNING', 'Chip Tuning' and 'ECU Remapping'. OBD stands for On Board Diagnostic. To make sense of this the word port is important because without the port, on board diagnostics would not actually exist; just as it didn't exist in the 1980's. Ay reference to OBD remapping is simply just engine tuning, or engine remapping completed via the use of the car's obd port..


Our PERFORMANCE REMAP SOFTWARE is developed to work on a standard vehicle maintaining manufacturer levels of reliability and original service intervals. Our Quantum Red calibration is specially designed for High Power & Ultimate Performance.
