ECU Remapping in Ratby

Nothing that gets written has to stay

Before a single value is altered, the original file comes off the ECU and gets stored. That is the whole reason this work can be offered honestly. If you sell the car, hand a lease back, or want a dealer looking at something without any awkward conversation, the vehicle goes back to the calibration it was delivered with and there is very little time or fuss involved in doing it.

It also means you are allowed to change your mind for no particular reason. Some people want to drive both and decide for themselves which they prefer, and that is a perfectly sensible way to spend an afternoon. Anybody unwilling to store your original file, or unable to tell you plainly how the car gets put back, is asking you to take a risk you do not need to take.

The one thing that is not reversible by staying quiet is the paperwork. A remap is a modification and it needs declaring to your insurer, the same as any other change. Most treat it as routine. The problem only ever appears when it was never mentioned and then surfaces in the middle of a claim.

What you are actually paying for

Ratby sits under five miles from Leicester, so a lot of the driving here happens at moderate speed on ordinary roads, with the occasional longer run north or west. That is the use the file gets written around. The change lands low and mid range, which is where you spend nearly all of your time, and the description of it is about effort rather than numbers: the car doing what you asked without being worked hard for it.

You will not get a percentage over the phone, because a figure given before the car has been seen is a guess dressed up as expertise. Two vehicles wearing the same badge and the same engine code can be in very different states of health, and only one approach notices the difference. There is background on the engine side under performance remapping in Leicester if you want it first.

The work itself is a sequence rather than an upload. Read and store the original, log the engine on the road, adjust fuelling, boost and timing for how the vehicle is used, then log it again, because measuring the result is the only honest way to know the change did what it was meant to.

What will not be done, on any vehicle

Diesel particulate filters do not get removed here, and no software gets written that pretends a missing one is still fitted. It fails an MOT and it makes the vehicle unlawful to use on the road. The same applies to EGR and AdBlue: they get diagnosed, repaired and made to work as designed, never blanked, deleted or emulated. If a delete is what you are after, we are the wrong people and it is better said now than after you have waited in.

A map is also not a repair, which is the other half of the same honesty. A tired turbo, a leaking injector, a sticking valve or a part blocked filter will not be fixed by adding torque, they will simply be found sooner. Where the symptoms point that way the job becomes diagnostic, and there is more on that under DPF cleaning and diagnostics in Leicester.

Five villages, and thirteen miles of road to get here

This page covers Groby, Kirby Muxloe, Kirby Fields, Leicester Forest East and Bondman Hays as well as Ratby itself. All of them are close enough that the arrangements are identical, and if you are nearer somewhere else, Desford is under three miles, with Anstey, Markfield and Enderby all within four and a half and each with a page of their own.

The workshop is on Rugby Road in Lutterworth, about thirteen miles south of you. That is far enough to want a time agreed rather than a rough window, and far enough that the vehicle details are worth having in advance so the right kit travels. Once here it is an ordinary visit: a driveway is ideal, a quiet street usually works, and an hour to ninety minutes covers it.
