ECU Remap MOT Service Diagnostics Wheel Alignment
Why do you want ECU Remapping?

All modern engines are controlled by an electronic brain called the Engine Control Unit (ECU). The files written into this (called the Map) tell your engine how to behave. Because of the diverse market vehicles are sold in, the settings in this Map must cover all types of conditions for example poor fuel, extremes of temperature or altitude, poor servicing etc. This means of course that as your engine has such generic files written into it, that it is running at less than its full efficiency.

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.

Benefits of ECU Remapping

for Turbo Charged Petrol and Diesel Engines

Performance Improvements

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.

for Non-Turbo Charged Petrol Engines

Performance Improvements

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.

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 recalibration 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.
