ECU Tuning


All modern cars and vans on the road today have an ECU (ENGINE CONTROL UNIT). This Engine Control Unit can almost be called the vehicles’mind’ and has a tiny chip that takes data from various sensors throughout the motor. It analyses information such as the motor temperature, accelerator pedal angle, oxygen content in the burnt exhaust gases in addition to many additional parameters. Utilizing the information from these sensors it may then add the ideal amount of fuel, at just the correct time to provide a good mixture of fuel economy, performance and energy control when pulling off, overtaking, pottering down the street or melts the motorway.


When a producer develops a brand new car they must take into account all of the conditions it might be subjected to in all of the regions in which they wish 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 must make compromises to the map to consider these possible differing operating requirements. These may include sub-standard fuels, extremes in temperature and altitude, differing emission legislation and even the risk that vehicle may not be serviced on a regular basis and in accordance with the manufacturers recommended directions. fix my blocked dpf

ECU remapping is taking a read from the ECU’s processing chip of their vehicles regular compromised map and adjusting a variety of parameters inside the map like fuel pressure, increase pressure (on turbocharged applications) ignition progress and throttle pedal controller among other people to launch the genuine performance from the engine. It’s a completely safe procedure since it’s only giving the motor the functionality it ought to have had in the first place before each of the compromises were implemented to the original programming. Every engine will have its own unique map and by adjusting this we could fine tune the qualities of the engine; unleashing more energy and oftentimes reduce fuel consumption also.


ECU programming won’t only improve the engines torque and power figures it will also sharpen the throttle response and widen the power-band. This is likely to produce the energy delivery far more linear, which then will make the vehicle feel a good deal more difficult to drive and the motor more flexible. Frequently, the vehicles electricity output is restricted by the manufacturer for no other reason than to make sure that the vehicle matches into a course to match fleet buyers. As a driving enthusiast, you do not need or desire such restrictions placed upon your vehicles ECU and its performance thus you are able to benefit from the hidden energy and torque locked out within your engine management system.

The other main advantage of remapping will be a reduction in gas consumption. Together with the extra torque particularly at the bottom of the rev range you will observe a fuel saving as it will need less throttle input to maintain motorway speeds, you can push in a higher gear at a slower rate in addition to helping significantly if fully laden, towing or on gradients and even in start stop traffic.

Many see the contemporary crop of Turbocharged diesels as the future of road car’s chip trimming. Even in North America, a nation famed for its love of the petrol engine is starting to come around to the benefits of turbo diesel passenger cars in particular. These engines offer you excellent potential for reliable low cost pruning without eliminating any of their appeal of buying and running a turbo diesel driven car, such as market, reliability and durability.
After your ECU update to your turbocharged diesel motor, you will enjoy:

Increased horsepower
Greater torque
Better throttle Reaction
Smoother power delivery
Improved fuel economy
Safer overtaking

Turbocharged petrol engines have always been considered to be the sports flagship engine for good reason. They boast far higher power & torque amounts than a non-turbocharged power-plant with comparable displacement and are often fitted into the producer’s flagship models. They are also ideal candidates for programming as the ECU also controls the wastegate (turbo boost pressure control).

The normally aspirated gas engine, although not being the simplest of motors to tune, can nevertheless benefit from a 10-15% power increase with additional torque by careful reprogramming of various engine parameters inside the map. Parameters like the fuel and ignition curves can be fine tuned to give much better power & torque output. On some engines the camshaft timing may also be tuned within the map, giving additional improvements.

In many cases,’after market’ tuning items like free flowing exhausts, high flow air filters and re-profiled camshafts can only be fully used from the motor after the necessary alterations are made inside the ECU. Careful recalibration of the correct maps can unlock the potential of your engine parts. Further power gains might also be available when a higher octane fuel is utilized, allowing for much more ignition timing.


When we remap a vehicle, especially when fuel saving is your priority we concentrate on improving the low end torque particularly and widening the power-band as far as we could.

This increase in low end torque will mean less throttle pedal input is required to keep cruising speeds, when fully laden or when to a gradient. It will also indicate that the automobile will be more comfortable in higher gears at slower speeds also requiring fewer gear changes total.

If you combine these variables with adjusting your driving style to create the most of the excess low end torque you will see a rise in fuel consumption. This is quite effective on turbo-diesel engines where the savings may be up to 20%!


We don’t change any hardware in your car or truck, we just alter the operating parameters in the ECU’s program or’map’. In many cases the map stored on the ECU’s chip can be accessed via the on-board diagnostics port (OBD) in the automobile, normally found under the dashboard. In some newer versions the ECU will have to be taken out of the vehicle and the casing started, our technicians will then use expert tools to read the original map straight from the processing processor.

The technician will then upload the original map to our chart composing team who will adapt the parameters to increase the performance, fuel economy or a smart combination of both. Based upon the automobile and ECU kind the processor tuning procedure can take under an hour and if at any time you would like to return your vehicles ECU to its original default settings, this may be carried out easily and free of charge since we always keep a copy of the original software for a backup.
