If you are not a mechanic then you probably won't even know what an ECU is
. However what you should be aware of that an ECU is vital to the smooth running of your car. It stands to reason then that maintenance and ECU repairs are important and should be carried out correctly.
The engine control unit (ECU) is the part of your car that controls the fuel injection system. It also deals with things such as the idle speed control system and ignition timing. Even if you don't know the ins and outs of how these things work, it is obvious that they are important to the running of your vehicle and that you need them to be in tip top condition in order for your car to run as good as possible.
The engine control unit also helps with things such as air conditioning and the controls the power that is given to the fuel pump. For the more technical minded you may also be interested to know that the ECU has an 8-bit microprocessor. It also has both random access memory and read only memory.
If your ECU unit breaks down then your car will simply not run. Once you have a car it doesn't take long for you to become dependent on it that means when it breaks you want to get it fixed as soon as possible. ECU repairs can be carried out by skilled mechanics although of course the length of time that they take to fix will depend on the extent of the repairs that are needed.
It is probably a good idea to look into garages in your local area that could carry out ECU repairs if needed. That way if you do find that your ECU breaks you will know who to contact straight away. This saves you time ringing around trying to find a garage willing to carry out the repairs, when all you want to do is get it fixed as quickly as possible. The quicker you get your car fixed, the quicker you can get back on the road which is your priority when you realise your car is broken.
