So what is a remap?
To understand a Remap, first you need to understand that internal combustion engines (diesel and petrol engines) require a mixture of fuel and air. To create maximum power whilst keeping fuel economy manageable the mixture of fuel to air must be precise. Carburetors used to manage this mixture for us, but as cars progressed, car fueling progressed; and now we have fuel injection or in some cases, direct fuel injection.
The vehicle has an electronic control unit (ECU) to control the engine parameters which will have a map table that tells the injection system to provide a certain amount of fuel at each point in the rev range, our remap will adjust that map table to suit your requirements.

If you can make the power quoted, why doesn't the manufacturer offer that level of power from factory?
There are two main reasons for this.
1. When cars are brand new the emissions standards they are held against are a lot more stringent vs. cars that are second hand, so a car may have to show 99g/km of carbon dioxide when it leaves the factory, but the very next day 149g/km will still be its acceptable limit.2. If Mercedes-Benz sells a C63 for £60,000 and an E63 for £80,000 and they put the same engine in both, if they had the same map the C63 would be faster as it is the smaller, lighter car. So they limit the power in the C63 to 450hp, whereas the E63 makes 490hp to ensure the E63 is slightly faster and it will entice people to buy the more expensive car.

A competitors map can produce more power, why is this?
We are often asked why our maps don’t make more power, the difference with our map and a lot of competitors maps is that we aren’t aiming for the peak ‘pub figure’ but we aim for drivability and reliability, that’s why we offer a lifetime software warranty on all maps and a mechanical warranty on vehicles under 90,000 miles.

If you Remap my car, will the back be covered in soot?
No, it will not.
With cheaper remaps on diesels it’s very easy to dump more fuel into the system and increase boost to compensate for this, thus creating more power. The problem with using this concept is you end up with a lot of unburnt fuel that ends up coming out the exhaust in the form of soot due to the inherent lack of volumetric efficiency of these engines.
Where these cheaper maps change one or two parts of the map, our maps change up to 112 aspects by talking to the various sensors in your cars systems so every part of the car knows what to expect, this allows the car to run at a safe level, all whilst ensuring all the fuel that you’ve paid for is actually being used. -
What is a 'Stage 1'?
In the tuning community various maps are referred to in stages. Stage 1 is usually completely standard physically, Stage 2 is usually for cars that have had a cold air intake and a exhaust downpipe upgrade, and it goes on from there.
Truth be told, every company has different definitions of their tuning stages so that’s why we’ve split ours into 4 options
Eco Remap - An economy remap, creates the least power, but the most fuel economy
(No other modifications required)
Combined Remap - A mid point of an Eco Remap and a Power Remap
(No other modifications required)
Power Remap (Stage 1) - This is our most common remap as it will still provide better fuel economy, but it will improve performance most with no extra hardware required.
(No other modifications required)
Power Remap (Stage 1R) - This is a similar map to the Stage 1, but it has an uprated air intake, this can either be fitted by yourself or by us on the day. This will provide a minor performance upgrade but it will increase intake noise and allow the vehicle to rev more freely. -
What fuel economy returns can I see?
The answer depends totally on how you drive. If you drive reasonably sensibly you can see up to 30% better fuel economy. If you drive with your foot to the floor the fuel economy will be the same, if not, a little bit worse.
