Remapping
Performance tuning the easy way
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 optimizing 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 vehicle may not be serviced on a regular basis and in accordance with the manufacturers recommended instructions.
ECU remapping is taking a read from the ECU’s processing chip of the vehicles standard compromised map and adjusting various parameters within the map. These include 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.
Benefits of ECU Remapping
ECU remapping will not only improve the engines power and torque figures it will also sharpen the throttle response and widen the power-band.
This will make the power delivery a lot more linear, which in turn will make the vehicle feel a lot livelier to drive and the engine more flexible. Frequently, the vehicles power output is restricted by the manufacturer for no other reason than to ensure that the vehicle fits into a class to suit fleet buyers.
As a driving enthusiast, you do not need or want such restrictions placed upon your vehicles ECU and its performance therefore you can benefit from the hidden power and torque locked away within your engine management system.
The other main benefit of remapping will be a reduction in fuel consumption.
With the extra torque especially at the bottom of the rev range you will see a fuel saving as it will require less throttle input to maintain motorway speeds, you can drive in a higher gear at a slower speed as well as helping significantly when fully laden, towing or on gradients and even in start stop traffic.
ECU Remapping 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.
With the ECU upgrade you will enjoy:
Increased Horsepower
Increased Torque
Smoother Power Delivery
ECU Remapping for Turbocharged PETROL Engines
Turbocharged petrol engines have always been regarded as the sports flagship engine for good reason. They boost far higher power & torque figures than a non-turbocharged power-plant with similar displacement and are usually fitted to the manufacturer’s flagship models. They are also ideal candidates for remapping as the ECU also controls the waste-gate (turbo boost pressure control).
With the ECU upgrade you will enjoy:
Increased Horsepower
Increased Torque
Smoother Power Delivery
ECU Remapping for NON-Turbocharged Engines
The normally aspirated petrol engine, whilst not being the easiest of engines to tune, can still benefit from a 10-15% 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.
