ECU Remapping in Staverton

Nobody should lose a morning to this

The standard version of this job involves booking the car in somewhere, dropping it off, arranging a lift home or sitting about, then going back for it later. For a village where the nearest town is a couple of miles away and everything else is nine or more, that is most of a day gone for work that takes well under two hours.

We run a mobile service, so the equipment comes to the vehicle. A driveway is perfect, a farm yard or a bit of hard standing works fine, and a quiet lane is usually acceptable. What we need is somewhere the vehicle can sit with the engine able to run, the doors able to open, and a decent stretch of road nearby to drive it on properly. Out here that is the easy part.

The job itself is about an hour, a little longer on some vehicles. That is short enough to fit around whatever else your day is doing, and you get to watch it happen rather than hand the keys over and hope. There is more on how the mobile side works on our mobile ECU remapping in Rugby page.

What happens when we get there

First the original calibration is read off the ECU and stored. That is the safety net for everything afterwards, and it is why reverting is a small job rather than a drama. Then the engine is logged on the road, because a datasheet tells you what an engine of that type is supposed to do and logging tells you what yours is actually doing right now.

With that in front of us, fuelling, boost and timing get adjusted for how the vehicle is used rather than for an average of every owner in every market. Then it is driven and logged a second time. That final step is the one that separates a map from a gamble, because it is the only way to confirm the change did what it was intended to and that nothing is sitting outside sensible limits.

Nothing about being on a driveway makes that a lesser job. The single genuine exception is a small number of control units that have to be opened and read on a bench, and if yours is one of those we will tell you at the enquiry stage rather than discovering it in front of you.

When the honest answer is do not bother

We turn work down fairly often. If a vehicle has a fault stored, a service long overdue, a clutch that is already slipping or an engine that has been quietly getting worse, adding torque brings the failure forward. It does not cause a new problem so much as find the existing one, and it never picks a helpful moment to do it.

The other honest no is the money. Car remaps from £129, with vans and commercial vehicles quoted per vehicle. If your mileage is low and the driving is mostly short local trips, an economy biased map will take a very long time to repay that, and we would rather say so on the phone than take a booking that was never going to work out for you.

And we will not put a percentage or a power figure on anything before we have seen the vehicle, because any number offered at that stage is invented and everybody involved knows it. What we will tell you is where in the rev range the difference should show up, how it ought to feel from the driver's seat and what sort of driving it suits. That is the answer that actually helps you decide whether to spend the money.

The villages this page covers

Staverton is around fourteen and a half miles south of the workshop in Lutterworth, and one trip down covers a good deal of ground. This page now serves Badby, Byfield, Charwelton and Church Charwelton, Hellidon, Preston Capes, Fawsley, Upper and Lower Catesby, Upper and Lower Boddington and Westhorp alongside the village itself.

If a nearby town is closer to you, it has a page of its own. Daventry is a little over two miles and Welton about four. Rugby sits at nearly nine miles and Northampton at thirteen, which is the sort of distance that makes the mobile service worth having in the first place.
