Bespoke ECU Remapping

Bespoke ECU Remapping and Tuning


The first thing you might ask about ECU remapping is, well, what is it? With all the mod cons at our disposal in this day and age, it can often be difficult to choose which are worth investing your hard-earned money in, so it’s important to have a clear idea of exactly what you are purchasing before you do so. In the majority of modern vehicles, you will find an Engine Control Unit, commonly known as the ECU. As you may have gathered from the name, it’s a small computer unit that controls how the engine works. Due to the diversity of rules, regulations, climates and other variables, the manufacturers ensure the software is reset before it is sent out to the dealership. ECU remapping London is essentially modifying the default software in order to optimise the performance of your vehicle’s engine. As a result, driving your vehicle will be a much higher-octane experience. Your engine’s response, as well as its power delivery, will be markedly improved – and this is before you even consider the thrills you can obtain through ECU mapping’s positive effect on your car’s acceleration. At GAD Tuning , our London and Essex engine remapping service is one of the most comprehensive available on the market. No matter how glamourous the model, we have an experienced team who are committed to improving the performance of your car. From Aston Martin and Audi remapping to Mercedes and BMW remapping, our ECU remapping in Essex and London will help your car unlock that extra gear.

Wait in comfort


Wait in comfort in our luxury waiting room

Here at GAD Tuning the customer comfort and satisfaction is paramount! So when we initially planned our workshop refurbishment the first thing we did before we even started construction of our dyno cell was to increase the size of the waiting room.

We not only improved the size we also added more seating, larger kitchen, improved complimentary refreshments, opened up for more natural light, 458 Challenge wheel table, Large 50” 4k HDR TV, Netflix, Ps4 Pro with PlayStation VR all to accommodate the customers needs.

Our customers often watch movies, TV shows and play Gran turismo Sport in Virtual reality all while watching over the workshop as we work on there pride and joy.

They have access free of charge to beers, wine, soft drinks like Pepsi, Dr Pepper, sweats, chocolate and crisps.

This brief was very important to us as a large percentage of our customers come from literally all over the country and very often other countries.

We regularly have customers from Cornwall, Wales, Birmingham, Manchester, Leeds, Scotland and even Denmark, Monaco and Switzerland just to name a few so making it comfortable was key.
