ECU remapping is a special method which uses a bespoke software program to fine tune the engine of a car. A car engine is controlled by an engine management system (ECU). Remapping ECU is a way of improving the performance of the engine. The best and most reputable car remapping companies use specialist software which is tailored to suit a particular make of vehicle. The best car remapping services will also take your own individual requirements into consideration before remapping the car.
In today's modern cars, the engines are controlled by computers and therefore they rely heavily upon instructions from the car's computer. This is how it knows at what level to run effectively - the car's performance is in effect, run by the engine management system. Every engine is fitted with an array of sensors which will monitor the engine's performance while it is running. This data is sent to the ECU to tell it how the engine is performing. Things like throttle position, crank position and the airflow are all monitored by the sensors. Then the ECU, or Engine Control Unit, processes the data and gives the engine instructions so it runs at its best performance, in whatever the driving conditions are at the time.
A good remapping ECU service will increase the power and torque of a car, giving a much smoother and fuel efficient drive. It can also results in smoother and faster acceleration and better overtaking manoeuvrability and speeds.
If you are considering VW tuning the ECU on your car, you should be aware of companies claiming to be experts when they are really cheap imitations of the real thing. They may seem as though they are offering value for money remapping services when in actual fact they are simply using stock maps that are freely available online. Be careful, and make sure you choose a reputable car remapping service which uses bespoke software designed to fine tune your car engine to your own exact specifications, not the specifications of someone else. Using a less than reputable car remapping service can potentially damage your car engine so be extremely cautious when looking for a company.
A good company will spend time running full diagnostic tests on your car engine, and finding out what your requirements are. A professional will only commence with a car remapping when it has established that your engine is in good working order and there are no failing components in it. Remapping an engine which has failing components has the potential to cause serious damage, so a professional service will not do this. Make sure your engine is properly checked and all the relevant diagnostic tests are run prior to any car remapping being done.
If a company does try to do this to your car, just say no thanks and leave, then you can find a reputable and trustworthy car remapping service elsewhere.
Once you have successfully had your car remapped, you will immediately notice an improvement in how it performs and drives. There is no doubt you will fall in love with your car all over again!
