If you would like us to remap your ECU (Electronic Control Unit) we can come to you. Home, Work, or any other Location

Our mobile service covers the whole of the Northwest, including Lancashire, Manchester and Liverpool


In most cases the remap needs only our Technician to plug in a laptop to your car’s OBD port so is totally non invasive’

Occasionally some cars need to have the ECU removed from the vehicle, often referred to as ECU out or Bench remapping. this may involve removing other components to access the ECU. don’t worry everything will be but back exactly as it was prior to the remap.

When our technician arrives with you, existing software from your ECU is downloaded onto their laptop and transferred online to our workshop for analysis. Next, new software is created especially for your vehicle based on your specific requirements.

For example, if you’ve asked for performance software, that’s what we’ll focus on. Similarly, if the emphasis is on fuel economy, then that will be our focus.

We provide true custom software for you based on your requirements and on the software already on your ECU. we never use cheap generic files

Once your software is complete it’s sent online to our technician at your home or workplace who uploads it to your vehicle’s ECU. Then its time for a test drive to feel the difference!


We’re careful to create software that your car can safely cope with. For example, when increasing power and performance, we’d ensure the engine settings on your new ECU software were within the parameters of what your engine, transmission and exhaust system could cope with.

We always retain your original software in case you should ever require your vehicle’s original ECU software to be restored.

For your peace of mind and to show the confidence we place in our service, we’re happy to guarantee your satisfaction for 30 days. for any reason we will restore your ECU to its original settings and fully refund your money

All software installed onto your vehicle’s ECU carries a lifetime guarantee.


All modern cars and vans on the road today have an ECU (ENGINE CONTROL UNIT). This Engine Control Unit can almost be described as the vehicles brain and contains a small processor that takes information from various sensors throughout the engine. It analyses information such as the engine temperature, accelerator pedal angle, oxygen content in the burnt exhaust gases as well as many more parameters. Using the information from these sensors it can then add the right quantity of fuel, at just the right time to provide a good mix of fuel economy, performance and emission control when pulling away, overtaking, pottering down the road or zooming down the motorway.


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 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 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.
