ECU Remapping

ECU Tuning refers to the process of replacing the original factory installed map used by the ECU of a car, to a tuned version. Remapping is another word commonly used in the UK for the same meaning as ECU Tuning.

Typically the performance gain you would expect after having your car remapped are
Performance gain in BHP & Torque
Petrol N/A Engine: 5 - 10%
Petrol Turbocharged: 10 - 30%
Diesel Turbocharged: 20 - 40%
Process of remapping a car usually takes between 2 - 8 hours, depending on the type of car model, as the procedures between cars could be completely different. Some cars may even need up to 2 days to complete a remap.
Difference between REMAP & CHIPTUNING?

Chiptuning or chipping, as some called it, is an ancient method of upgrading a car's performance. It involves replacing the original eeprom/chip in your ECU's board with a tuned version. The improvement is usually 'raw' and not refined, usually suitable for old vehicles Pre-2000. Despite being an old technology, there are however, still a lot of chipping companies around offering the services at reasonably cheap price. Although we do not provide chiptuning services, we still retain the use of this word in our website as it may relates better to some people.

Remap on the other hand, is the most complex and comprehensive procedure to alter the most parameters in a car's ECU. It result in the smoothest, highest gain and finest drivability experience with all the enhanced parameters working harmoniously together. Process involves extracting the map from the ECU, modifies the map and then insert the modified map back into your ECU. We keep a copy of the Original Map of your car.

Extraction process of the map can be quite different depending on the type of vehicle. The easiest being extraction through OBDII, but not all cars has had this solution available. Most Japanese, Korean and Malaysian made cars' map are still being extracted manually by wire connection on the ECU itself.
Why ECU Tune or REMAP?
During the development of an automobile the manufacturers have to, in many respects, find compromises in terms of fuel efficiency, horsepower output, drivability and these days, the most important issue, exhaust emissions. Factors like fuel quality, ambient temperature, air quality, maintenance, operational circumstances etc. as well as financial aspects i.e., insurance classifications, have to be taken under consideration. The manufacturers have to assure operational reliability for the final product worldwide, which means, that in most cases the actual engine potential is not reached.
Therefore in Stock Car, the ignition, injection, boost,
- etc. patterns programmed, are on the "safe side". In another word, too conservative.
Remapping your car unleashes the full potential of your car engines. You will experience:-

  • More Horsepower
  • More Torque
  • Removal of Speed Limiter
  • Improved throttle response
  • Smoother power delivery
  • Safer overtaking
  • Better fuel economy at cruising

The improvements above are all achieved by very careful matching of parameters such as fuel delivery rates & ignition timing along with adjustments to maps that electronically limit torque, throttle response and top speed. All this information in your ECU calibration file is carefully optimised to our exacting standards and then programmed back into your ECU and the vehicle tested.
