ECU Remapping in Blaby

Not at all, but it changes what you should be asking for. Short cold journeys mean the top of the rev range is irrelevant to you, so the map gets biased towards low and mid range pull instead. What short runs do not do is fix a fuel consumption figure, because a cold engine is always going to be thirsty for the first few miles regardless of what the software says.

No, and we would be wary of anybody who says it will. A blocked filter has a cause, and until that cause is found you are just resetting the clock. Diagnostics, a proper clean and a forced regeneration are the actual job. Once that is sorted, a well written map can help by reducing how much soot the engine makes in the first place. That is a second step, not the fix.

No. Removing a particulate filter is an MOT failure and makes the vehicle unlawful to use on the road, and we will not write software that pretends a missing filter is still there. EGR and AdBlue faults get diagnosed and repaired. Plenty of AdBlue problems turn out to be a sensor, a heater or crystallisation rather than the whole system, and they are worth looking at properly.

Yes, and it is one of the easier journeys we make at around eight and a half miles from the Lutterworth workshop. Driveway, street, yard or a work car park all work, provided the car can sit with the engine able to run and there is room to open a door. If you would rather bring it to us, the workshop is on Rugby Road in Lutterworth.

Countesthorpe, Glen Parva, Eyres Monsell and Peatling Magna are all covered by this page. Whetstone, Narborough, Enderby and Wigston are all within a couple of miles and have pages of their own. Honestly, the page boundaries matter less than you would think. Ring, say roughly where the car sits, and we will tell you whether it is an easy visit.

Usually about an hour to ninety minutes. That covers reading and saving the original calibration, logging the engine on the road, writing and loading the map, and logging again to check the result. Some control units take longer to read and write than others, and if yours is one of them we will tell you when you book rather than on the day.

Yes. The original calibration is read and stored before anything is written to the ECU, so the car can go back to precisely the state it was in when we arrived. People ask for that when selling, when handing a lease back, or when a dealer wants the vehicle standard for a warranty conversation. It takes very little time and there is no awkwardness about asking.

Yes. A remap is a modification in the same way a set of wheels or a suspension change is, and it should be declared. Most insurers deal with it without any fuss at all once they have been told. The only time it becomes a real problem is when it was never declared and then comes up during a claim, which is the worst possible moment to find out.

Both. Turbocharged petrols usually respond well and make up a fair share of the work. Naturally aspirated petrols have far less margin in the software, and on some of them the honest answer is that the gain would not justify the money, particularly on the short local driving that Blaby produces. Tell us the exact engine and we will say which category yours falls into.

Make, model, year and engine size, roughly where in Blaby the car is parked, and what you actually want out of it. Mention any warning lights, any recent work and anything odd about how it has been running. That conversation usually decides whether a map is worth doing for you at all, and it costs you nothing to have it.
