Economy Remapping and Fuel Saving Maps in Rugby

Probably not, and we would rather say so. A fuel saving map pays for itself through repetition. If the car does a few short local trips in the week and one longer run at the weekend, there is not enough fuel going through it for the saving to add up to anything meaningful. If your weekend driving is genuinely substantial, tell us the numbers and we will look again.

We will not give you a percentage before seeing the vehicle, because any figure quoted blind is a guess. What we can do is give you a realistic expectation for your specific car once we have looked at it, and be honest about how much of it depends on how you drive afterwards. The numbers you see advertised are best cases on the most suitable engines.

No. Nothing is turned down. The point is to bring usable torque lower in the rev range so the engine achieves the same thing at lower revs and in a taller gear. Most people say the car feels easier to drive rather than slower, because it needs fewer gear changes to cover the same journey.

Turbocharged diesels covering consistent mileage on motorways and dual carriageways, which describes a good number of the cars doing the daily run out of Rugby. The worst case is a small petrol doing short cold journeys around town, where the engine never settles anywhere long enough for the map to do much for you.

That is arithmetic rather than opinion. Take what you spend on fuel in a typical week and work from there. A fixed daily commute makes the payback short and predictable. Occasional use makes it long enough that we would usually advise against bothering. Give us the weekly mileage and we will do the sum with you on the phone.

You will probably feel the car pulling more easily from low revs, which makes that kind of driving less tiresome. The fuel figure will move much less than it would for somebody doing settled motorway miles, because savings come from sustained running rather than from constant acceleration and braking. It is a driveability gain more than an economy one, and we would call it that.

Yes, when written within the tolerances of the engine and drivetrain. An economy biased map generally asks less of an engine than a performance one, not more. The vehicle is logged before and after so we can see what is actually happening rather than assuming, and the original file is saved in case anything ever needs reverting.

To a degree, and most road maps are a compromise anyway. What we do is bias that compromise towards whichever matters more to you, so be honest about which it is. Asking for maximum economy and then enjoying the extra pull every time you join the M1 is a common way to end up with neither.

Yes. It is a modification regardless of whether it is aimed at economy or at performance, and it should be declared like any other change to the vehicle. Most insurers are entirely relaxed about it once told. The issue only ever arises when it is undeclared and then surfaces during a claim.

Not on its own, and anyone saying otherwise is selling rather than diagnosing. A filter that keeps loading has a cause, and that cause needs finding first. Once it is sorted, a properly written map can help by reducing how much soot the engine produces in the first place. That is a second step, not the fix, and it starts with diagnostics rather than software.

Yes. The original calibration is saved before anything is written, so the car can be returned to exactly how it was. That matters if you are selling it, handing back a lease, or if a dealer wants the vehicle standard for a warranty discussion. Putting it back is a quick job and there is no drama about asking.

We do, and Rugby is one of the closest towns to the workshop in Lutterworth so it is an easy visit. Car remaps start from £129, with vans and commercial vehicles quoted per vehicle. Before any of that, ring and tell us your weekly mileage, because that is what decides whether this is worth your money at all.
