What is Mapping?
'Mapping' is the optimisation of your cars ECU (engine control unit). It may also be known as a power-train control module (PCM), or engine control module (ECM).
Within the ECU is a program to control your engine. It receives and processes signals from the environment, driver and engine. Examples are: air temp, throttle position, manifold pressure, engine water temp, engine rpm, etc.
The ECU then processes this information to calculate the exact amount of fuel and the precise timing of the spark plugs under any running condition.
It does this by reading the input data and looking this up on an internal data table usually referred to as a 'map'. Modern ECUs have many maps, but two typical examples are the Fuel and Ignition maps. You can see a graphical representation of such a map on the top right of this article.
So why would you want to and in some cases need to have my car mapped?
There are many reasons why you may want to do this, not at least the fact that in some cases you stand to gain significant improvements in engine performance, but also the fact that many standard manufacturer programmes are quite conservative
The are also reasons why you really should have your car mapped. If you have made any significant mechanical changes to your engine, for example air filter/exhaust/increased boost. Then this will push the ECU outside the scope for which it was programmed for. This can lead to some potentially dangerous running conditions which may if left unchecked ultimately result in engine failure, or at least sub optimal performance.
Its a sad but true fact that so many modified cars are not running nearly their best as their owners would rather spend thousands on performance parts yet are unwilling to spend a fraction of that on the most important part that makes it all work in harmony - the ECU! The fact that the car may indeed feel fine to drive also is not a totally clear indicator that all is well, and so at the very least we would always recommend a dyno power run to ensure that all is well.
I am interested, what next?
Simple! You need to get in touch with us! We will then discuss your needs and tailor our service to suit you. After we have all the information we require we will organise a convenient time for you to come and have the car mapped, and we go from there. Its a totally customised service for you and your car.
How much will this cost me?
If your car has a totally standard ECU and has never been touched before then it will require a hardware modification. Our service for this including mapping is £330. However if your a returning customer then the price is £150. These prices exclude the use of the rolling road. This is usually an additional £70 per session.
