ECU Remapping basically means to fine tune your cars software programe that controls the Engine Management System which is known as the Engine Control Unit.
The modern engines of today heavily rely on a computer controlled engine management system. So basically an engine uses sensors to monitor most of what your car is doing such as; throttle position, airflow, crank position and much more. The ECU (Engine Control Unit) is then sent this information to processe which will give top performance for any driving condition.
Why remap my ECU?
Manufacturers have adopted the ‘one map fits all policy’ for their world wide vehicle distribution. Within this one map they need to account for necessary factors in each export country which will be alot different. The manufacturers have to consider many things such as emissions, climate, weather and even the quality of fuel. This means that no factury ECU is never produced and optimised for a single country or environment.
How can AA Technik help?
What we do is to first read your engines map file, we then have to modify the file to best suite you and your car then upload it back on to your ECU. For this to be done correctly we will need you to tell us your individual requirements and what it is you would like from your vehicles remap. ECU Remapping makes it easy to give your cars engine extra power and torque without issues of reliability. Reports of owners seeing fuel economy improvements once this engine remapping is done are often. Although lots of customers see improved fuel economy you should be aware that this will all depend on how you drive like your driving style and how heavy you are on the right foot.
ECU Remapping increases the power and torque to provide a much smoother drive. Throughout your rev range you get increased flexibility which allows smoother acceleration and ease for better overtaking power.
Imitation Cheaping Beware!
You should be aware that some companies today offer what looks like a nice cheap value ECU remap service. But most companies like this are using stock maps which are NOT custom to your cars requirements and have more then likely been got cheap online. Due to this they could be for any car not specificly for yours which could damage your engine.
A full engine diagnostics check should be done before ECU remapping is carried out, this should show us and potential problems and/or parts that may need replacing. ECU remapping will not caouse any type of failure but it can speed up any already failing components which you should be aware of.
What are the expected improvements?
You will see improvements in both the engines power and torque all the way through your rev range. Fuel economy improvements are also a possibility but this will depend on your driving systems. We have a list for different engine types average improvements below.
Non-turbo Petrol:
ECU Remapping on a normally aspirated engine will give you on average around 10 – 15%(bhp) power increase, this will depend on the exact specifications of your engine, and on average around 15 – 20% (Nm) throughout rev range. Response to the engine a lighter throttle will improve.
Turbo Petrol:
ECU Remapping on a modified engine with a turbo engine will on average give you an extra 20 – 30% (bhp) with an average troque increase of 20 – 40% (Nm) depending on the secifications of your engine. This large increase of pwoer and torque will improve flexibility of your engine greatly throughout the rev range and in all gears.
Turbo Diesel:
With the greatest gain of any engine type, ECU Remapping on a Turbo Diesel will on average give you an extra 25- 50% (bhp) and 50 – 75% (Nm) depending on sepcifications of your engine. Greatly improved engine response throughout whole rev range and all gears. Its well known that diesel engines provide huge amounts of torque and top performance in all gears. After a modern Turbo Diesel has had a ECU Remap most of them will have a great ability over most petrol cars when in normal driving conditions.
