ECU Remapping in Market Harborough

Not quite twelve miles, straight east of the workshop on Rugby Road in Lutterworth. That makes it one of the shorter runs we do, so getting a slot is usually straightforward. We are a mobile service, so in almost every case we come to you and work on the car where it is parked. The workshop is there if you would sooner bring it in, and the job is identical either way.

That is the use a custom map suits best. The change sits through the middle of the rev range, which is where settled cruising and overtaking both live, so you feel it on the driving you already do every week. Less shuffling between gears on a gradient, less planning before you pull out of a junction. If you only ever crawled a mile to the shops, we would tell you it was not worth your money.

No, and be wary of anybody who will. A number quoted before the original calibration has been read off your particular car is a guess dressed up as a fact. What we will tell you is where in the rev range you should notice the difference and how it will feel doing the driving you have described to us. The figures people put in adverts are not the part you experience from the driver's seat.

No. We do not remove, delete, blank or emulate DPF, EGR or AdBlue systems on any vehicle, on any map, for anybody. It is an MOT failure and it is unlawful to use the car on the road afterwards. What we can do is diagnose the filter properly with live data, clean it, force a regeneration where the filter will take one, and put right the underlying fault that is loading it up.

Car remaps start from £129. Vans and commercial vehicles are quoted per vehicle, because the work involved varies far more between them. Ring with the make, model, year and engine and you will get the real figure for your car rather than a range to squint at. If we think the job is not worth doing on your vehicle, you will hear that on the phone rather than after we have arrived.

Budget an hour to ninety minutes. That covers reading and storing the original file, a road drive to log how the engine is behaving, writing and loading the new map, then a second drive to confirm it has done what it was meant to. Some control units read and write more slowly than others, and if yours is one of the slow ones we will mention it when you book rather than on the day.

Great Bowden, Little Bowden, Lubenham, Foxton, Marston Trussell, East Farndon, Theddingworth, Husbands Bosworth, Great Oxendon, Clipston, Sibbertoft, Sulby, Thorpe Langton and Dingley, along with Market Harborough itself. Kibworth Harcourt and Ashley sit around four or five miles out, Desborough and Harrington about five, and each of those has a page of its own if you happen to be closer to one of them.

Yes. The untouched original is read out of the ECU and stored before a single line of the new map goes anywhere near it, so the car can be returned exactly as it arrived whenever you want. People usually ask before selling, at the end of a lease, or before a main dealer looks at something unrelated. Putting it back takes very little time and does not need another long appointment.

That depends almost entirely on your right foot. Drive the way you drive now and a lot of cars use the same or a touch less, because the engine is doing the same work with less effort behind it. Drive the way the extra response tempts you to and it will cost you more. On the longer runs out of Market Harborough most people settle somewhere between the two without really thinking about it.

Yes, and fairly often. A slipping clutch, a turbo that already sounds unhappy, a fault code nobody has got to the bottom of, or a service history with a long gap in the middle of it. Extra torque does not create those problems but it will bring them to the surface sooner. We would rather say so on the phone, get the car sorted first, and do the map afterwards.
