AP Autocare Performance Tuning

Our custom performance remaps enable us to tailor the software in your vehicle whether is a car, van or lorry so you get the most from its performance. Our professional software developers have years and years of experience customising vehicle software and each one we carry out is vehicle specific.

Vehicle manufacturers produce software for a vehicles Engine Control Unit (ECU), also known as an Engine Control Module (ECM). It is a type of electronic control unit that controls a series of actuators on an internal combustion engine to ensure optimal engine performance and control the key functions of a car’s engine.

ECU is critical for measuring the systems operating throughout a car’s engine and has a range of sensors which feed into it, therefore, if something isn’t working correctly or isn’t re-mapped correctly then critical engine problems can arise.

Vehicle manufacturers tailor the ECU for vehicles in line with where they are manufactured for so they work in that particular climate and altitude; hot climates, cold climates and countries with poor quality fuel, and this can result in you not being able to get the best performance from your vehicle.

Having a custom performance remap with AP Autocare enables us to tailor the software so you get the most from your vehicle’s performance, in line with your requirements.

AP Autocare Custom Performance Remap on your petrol or diesel vehicle will:

  • Increase Horsepower
  • Increase Torque throughout the rev range
  • Better throttle response
  • Smooth power delivery

AP Autocare Economy Tuning

At AP Autocare we can remap your vehicles software specifically aimed at fuel savings if that’s what you are looking for. An economy tuning focuses on increasing lower end torque which will in turn lead to better driving in higher gears at lower rpms, and by adjusting the drivability this leads to less throttle requirement. The savings in fuel consumption vary but will be particularly best on turbo-charged diesel engines with possible gains of up to 20%.

AP Autocare Engine Re-Mapping FAQ's

What is engine re-mapping?

Engine re-mapping is a process of changing your car engine's computer which is the Engine Control Unit (ECU). A professional and experienced garage like AP Autocare can change and overwrite the program with new software, customising and improving the functions and performance of your car.

In summary, vehicle manufacturers sell their cars all over the world and this means that the software settings on the ECU of vehicles manufactured for a particular country must take into account its climate, laws & restrictions and varying quality of fuels. Engine remapping is the modification/replacement of the manufactures default software on a vehicles ECU which results in improved performance and fuel economy.

How does engine re-mapping work?

A vehicle remap replaces manufacturers default software on its ECU, overwriting it with new software which can be programmed to optimize the cars overall performance.

The tuned software is plugged into your cars serial port (or OBD port) which then overwrites the engine map with the new version to enhance its engine performance. You should always use a reputable and professional garage like AP Autocare to carry out an engine remap on your vehicle as they are partnered with Pendle Performance who are the UK experts in engine re-mapping. Having the latest engine re-mapping state of the art equipment and professional software experts that have the experience and know how to re-map your vehicles engine results in the performance you are looking for.

Why would you have your vehicles engine re-mapped?

There are lots of different reasons to have your vehicle’s engine remapped and these include:

  • Improved engine response when accelerating
  • The overall torque and power will be noticeably increased
  • Smoother power delivery resulting in a safer driving experience and removing flat spots where possible
  • Easier and safer overtaking
  • Improved normal driving miles per gallon (MPG, decreasing fuel costs
  • Minimises your carbon footprint
  • Improved throttle response and the rev range will be enhanced

Do I need to tell my insurance company I have had my engine re-mapped?

Yes, you have to tell your insurance provider if you have had your vehicles engine re-mapped as re-mapping or chipping is considered to be a car modification, so it is notifiable. Engine re-mapping can result in a minimal increase to the cost of your car insurance premium so if you are concerned about this you should always check them first before you book it in to be done.

Does re-mapping shorten an engines life?

Engine re-mapping itself will not shorten the life of an engine if you have it done by a reputable and expert re-mapping garage like AP Autocare. Vehicle engines are more likely to be damaged by excessive acceleration and not having it serviced regularly to ensure all its working parts are in good working order, so this is the case with any vehicle, whether its engine has been re-mapped or not.

An engine remap doesn’t put any stress on the engine, so it doesn’t affect the longevity of it as long as it is done by a garage like AP Autocare who have the equipment and expertise to do it properly and safely.

Does engine re-mapping make a car faster?

Re-mapping your car’s ECU means you get the most out of its engine by improving its performance, fuel efficiency and responsiveness, which in turn will make the acceleration feel faster.

Does re-mapping affect your vehicles MOT?

Re-mapping your vehicles engine will not affect its annual MOT as long as it’s done by a professional and reputable garage like AP Autocare who is an expert in engine re-mapping as they will have the equipment and knowledge needed to do it safely.

Will having your vehicles engine re-mapped affect its manufacturer warranty?

The modification to your vehicle’s engine software won’t show up on a main dealer’s diagnostic equipment, therefore they won’t be aware that it has been done. Only software changes are made rather than any hardware changes, however, if a manufacturer was to know it can affect your vehicles warranty. At AP Autocare we keep all original files on our database so we can revert you back to the original file at any time you need it.

Can an engine re-map be reversed?

Yes the engine re-map process can be completely reversed without any trace as long as you use an expert garage like AP Autocare who has the knowledge, experience and specialist equipment to do it safely and who keep your original files so they can revert it back to its original file at any time.

What does Chiptuning / Remapping mean?

The term "chiptuning" dates back to the late 1980's and when we talk about chiptuning, we mean the reprogramming of the calibration data found inside the Engine Control Unit (ECU). Today, it is known as chiptuning, re-mapping and reflashing and it all means the same thing.

Will an engine re-map void my manufacturer’s warranty?
