ECU Remapping

We are an agent for Quantum Tuning, and are proud to be one of only a handful of garages to be certified IMI (Institute of the Motor Industry) Advanced tuners.

We can offer different tuning options to meet your needs, so whether you’re after maximum fuel economy, maximum power, or just the perfect mix of both.

We can tailor the software to your requirements. Additionally we can also provide exhaust system upgrades including high flow catalysts, induction kits, intercoolers etc. These modifications can only be fully utilised when incorporated in to the remap.

What is ECU Remapping?

When a manufacturer develops a new car they have to take into consideration all of the conditions it may be subjected to in all of the regions in which they intend to sell this model. This means instead of just optimising the ECU’s program or ‘map’ to deliver the best performance or the most fuel efficiency they have to make compromises to the map to take into account these potential differing operating conditions.

These could include sub-standard fuels, extremes in temperature and altitude, differing emission laws and even the possibility that vehicles may not be serviced on a regular basis and in accordance with the manufacturer’s recommended instructions.

ECU remapping involves accessing the processing chip of the vehicle’s standard, compromised ECU map and adjusting 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.

It is a completely safe process as it is just giving the engine the performance it should have had in the first place before all the compromises were applied to the original programming. Every engine will have its own unique map and by adjusting this we can fine tune the characteristics of the engine, unleashing more power and in many cases reduce fuel consumption too.

ECU Remapping Benefits for Turbocharged Diesel Engines

Many see the modern crop of Turbocharged diesels as the future of road car tuning. These engines offer fantastic potential for reliable low cost tuning without removing any of the appeal of buying and running a turbo diesel powered vehicle, such as economy, reliability and longevity. After your ECU upgrade to your turbocharged diesel engine, you will enjoy:

  • Increased horsepower
  • Increased torque
  • Better throttle response
  • Smoother power delivery
  • Improved fuel economy
  • Safer overtaking

Improvements in fuel consumption on petrol engine vehicles are smaller and nothing like that achieved by diesel vehicles.

ECU Remapping Benefits for Non-Turbocharged Petrol Engines

The normally aspirated petrol engine, whilst not being the easiest of engines to tune, can still benefit from a 8-15% power increase with added torque by careful reprogramming of various engine parameters within the map. Parameters such as the fuel and ignition curves can be fine-tuned to give better power & torque output.

On some engines the camshaft timing can also be tuned within the map, giving additional improvements.
In many cases, 'after-market' tuning items, such as freer flowing exhausts, high flow air filters and re-profiled camshafts, can only be fully utilised by the engine once the necessary adjustments have been made within the ECU. Careful re-calibration of the correct maps can unlock the potential of your new engine parts.

Further power gains may also be available when a higher octane fuel is used, allowing for more ignition timing.
