ECU Tuning

ECU Tuning


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


When a manufacturer develops a new car they have to take into account each of the conditions it may be subjected to in all the areas in which they wish to sell this version. This means instead of just optimising the ECU’s application or’map’ to deliver the best performance or the maximum fuel efficiency they have to make compromises into the map to take into account these potential differing operating conditions. These could consist of sub-standard fuels, extremes in temperature and elevation, differing emission legislation and even the possibility that vehicle might not be serviced on a regular basis and in accordance with the manufacturers recommended directions.

ECU remapping is shooting a study from your ECU’s processing chip of their vehicles regular compromised map and correcting a variety of parameters inside the map like fuel pressure, boost pressure (on turbocharged applications) ignition advance and throttle pedal controller amongst other people to launch the genuine performance from the engine. It is an entirely safe procedure since it’s just giving the engine the functionality it ought to have had in the first place before all the compromises were implemented to the original programming. Each engine will have its own distinctive map and by correcting this we can fine tune the qualities of the engine; unleashing more energy and oftentimes reduce fuel consumption too. fix my blocked dpf


ECU programming will not just improve the engines power and torque figures additionally, it will sharpen the throttle response and also expand the power-band. This will produce the power delivery a lot more linear, which in turn will produce the vehicle feel a lot more difficult to push and the motor more elastic. Frequently, the vehicles power output is limited by producer for no other reason than to ensure that the vehicle matches into a class to suit fleet buyers. As a driving enthusiast, you do not need or desire such restrictions placed upon your vehicles ECU and its functionality thus you are able to gain from the concealed energy and torque locked away within your motor management system.

The other principal advantage of remapping is going to be a reduction in fuel consumption. Together with the excess torque particularly at the bottom of the rev range you will observe a fuel saving as it will need less throttle input to keep motorway speeds, you can push in a higher gear at a slower speed in addition to helping considerably when fully laden, towing or on gradients as well as in start stop traffic.

Many see the modern crop of Turbocharged diesels because the future of street car’s chip tuning. Even in North America, a nation famous for its love of the gas engine is beginning to come around to the advantages of turbo diesel passenger cars in particular. These engines offer fantastic potential for reliable low cost pruning without eliminating any of their appeal of buying and running a turbo diesel driven car, such as economy, reliability and durability.
Following Your ECU upgrade to a turbocharged diesel motor, you may enjoy:

Increased horsepower
Increased torque
Better throttle Reaction
Smoother energy Shipping
Improved fuel economy
Safer overtaking


Turbocharged petrol engines have been considered to be the sport flagship engine for good reason. They boast far higher power & torque figures than the usual non-turbocharged power-plant with comparable displacement and are usually fitted to the producer’s flagship models. They are also ideal candidates for programming since the ECU also controls the wastegate (turbo boost pressure controller ).

The normally aspirated gas engine, although not being the easiest of motors to song, can still benefit from a 10-15% power boost with additional torque by cautious reprogramming of various engine parameters within the map. Parameters like the fuel and ignition curves may be fine tuned to provide better power & torque output. On some engines that the camshaft timing may also be tuned within the map, providing additional improvements.

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


As soon as we remap a vehicle, especially when fuel economy is the priority we focus on improving the low end torque particularly and extending the power-band as far as we could.

This growth in low end torque will mean less throttle pedal input is required to keep cruising speeds, when fully laden or if to a gradient. It will also mean that the vehicle will be comfortable in higher gears at slower speeds as well demanding fewer gear changes overall.

Should you combine these variables with adjusting your driving style to make the most of the extra low end torque you will find a rise in gas consumption. This is quite effective on turbo-diesel engines where the savings may be as much as 20%!


We do not alter any hardware in your vehicle, we just modify the operating parameters at the ECU’s program or’map’. In many cases the map stored on the ECU’s chip can be accessed through the on-board diagnostics port (OBD) at the automobile, typically found beneath the dashboard. In some newer models the ECU might have to be taken out of the automobile and the casing started, our technicians will then use specialist tools to read the original map straight from the processing chip.

The tech will then upload the initial map to our chart writing team that will adjust the parameters to increase the performance, fuel economy or a smart combination of both. Based upon the automobile and ECU type the chip tuning process can take under one hour and if at any time you would like to return your vehicles ECU to its default settings, this may be carried out easily and without any charge as we always keep a copy of the original applications as a backup.
