What is ECU Remapping?

What is an ECU? What is a Remap? How does a remap work?

ECU Remapping is the process that involves modifying the files and parameter data that is held within the ECU. The ECU has a whole table of data parameters which it uses to make real time adjustments whilst the engine is on. By ECU Remapping an ECU, we actually change the parameters within the data table, allowing more flexibility for the particular engine parameter. For example, we can modify the boost control parameter, allowing the turbo to work at a higher efficiency rate by increasing boost pressure.

ECU remapping & chip tuning is the modern day method of tuning a car for performance & economy. No car tune is complete without an ECU remap.

ECU Remapping Explained…

All modern vehicles are fitted with an Engine Control Unit or ‘ECU’, this is the engines ‘brain’ and it has evolved from a simple circuit that controlled the ignition to a very sophisticated computer that now controls virtually every aspect of the car’s engine, from the amount of boost the turbo will create, when and how much fuel is injected, when the spark plugs fire, what pressure the fuel rail runs at, Exhaust Gas Recirculation or EGR, and Diesel Particulate Filter or DPF function and regeneration.

When car manufacturers programme this ECU to control the engines function they have to be very liberal with the setting, taking into account the various markets that the car may end up in, the lack of maintenance certain owners will embellish on the car, poor fuel quality etc, etc.

However car manufacturers will also down tune certain cars so that they fit into certain market categories as well as certain insurance categories. Many times a lower model will be a down tuned higher model, using exactly the same engine components but simply down mapped at the factory to produce lower power.

ECU remapping is the art of subtlety tuning the engines running parameters to achieve a higher state of tune. An ECU that is well remapped will result in a car that not only produces more power and torque it also returns a higher MPG and will drive smoother and be far more responsive that its standard counterpart.

ECU REMAPPING TESTIMONIALS

WHAT CLIENTS SAY ABOUT US

My Alfa Romeo 159 immediately felt more lively and definitely more responsive with much more mid-range power. Average mpg used to be 42mpg and is now 51mpg... So much happier with my fuel bills now! Impressive stuff!

I want to say a big thankyou to the remapping team here for their expert Engine Tuning  and for ECU Remapping my BMW 520d last week. The only disadvantage is that I'm driving like a teenager again with all the extra bhp and torque! I know I'll see the benefits in fuel economy and increased MPG, when I start driving normally...Thanks again!

Originally met these guys at The Autosport Exhibition @ The NEC. Was thrilled to find out they were quite local to me. Can’t say enough how impressed I am at the success of the remap to my Audi A4 170bhp. The difference is phenomenal… sooooo smooth and the power comes so quick low down.

Since you re-mapped my VW Passat it’s just like driving a different car, the power is amazing and the performance as a whole is second to none. Every time I accelerate it's like pressing a warp drive pedal. And I’ve also noticed the MPG has gone up considerably. Great Performance Remapping.
