Economy Remapping and Fuel Saving Maps in Hinckley

For fuel, yes. A steady motorway run is the condition an economy map improves most, because load and revs are predictable and the saving repeats identically every day. The A5 version of the same journey spends a lot of its fuel accelerating away from roundabouts and sitting behind lorries at 50, and a map has far less influence there. Mix the two and your saving lands somewhere in between.

Not a question we will answer with a number before looking at the vehicle. It depends on the engine, the mileage, the roads and the right foot. What you will get instead is a realistic expectation for your specific case, which is considerably more useful than a headline figure taken from a car that is not yours.

No. It generally moves torque lower down so you need less of the rev range to do the same job. Most people describe it as feeling easier rather than slower, because it pulls from low revs and asks for fewer gear changes on the same journey.

Not at all, provided the total mileage is consistent week to week. What weakens the case is inconsistency in the kind of driving rather than in the direction. Two motorway commutes of similar length are effectively the same case. A motorway commute one day and a string of town errands the next is the mixed picture that is harder to predict.

Generally yes, if it is turbocharged and covering real distance. Turbo diesels respond well to this sort of calibration and they tend to be the vehicles doing the mileage that makes it worthwhile. Small petrols doing short journeys are the weakest case, and we will say so rather than take the work and disappoint you.

That is your mileage and your fuel price, so it is a sum we can do together in about two minutes on the phone. A five day commute of any real length pays back far faster than occasional use. If the answer comes out in years rather than months, you will hear that from us plainly.

Yes, when it is written for the vehicle and kept inside what the engine and drivetrain were designed to handle. An economy focused map generally asks less of an engine than a performance one does, not more, because the point of it is to have the engine working in an easier part of its range.

To an extent. Most road maps are a compromise and we bias that compromise towards whichever matters most to you. What does not work is expecting both ends of it at once. Decide which one you actually care about and be honest with yourself, because you are the one who has to drive it afterwards.

Possibly not, and it is worth checking before spending anything. A gradual rise in consumption often has a mechanical cause: a sticking EGR valve, an injector not sealing properly, a particulate filter quietly loading, or something as ordinary as tyre pressures. Mapping around a fault is expensive and it repairs nothing.

Yes. It is a modification to the vehicle, and the fact that it aims at fuel consumption rather than at power makes no difference to that at all. Declare it, get it noted on the policy, and it stops being something anybody can argue about later on when there is a claim to settle.

Very well, and a van doing a consistent daily round is among the best cases there is. The approach is the same, but the questions change, because a vehicle carrying weight all day has a different load profile from an empty car doing the same route.

Yes. The original calibration is saved before anything is written, so the vehicle can be put back exactly as it was at any point, whether that is for a sale, a lease return, or simply because you decided you preferred it the way it came.
