In short
We work on vehicles of any make: cars, vans, off-roaders, motorcycles, and commercial and agricultural vehicles. What determines how a remap is done isn't the badge but the engine, the ECU (Bosch, Continental, Delphi, Denso, Magneti Marelli…), its protection and the type of gearbox. We've put together guides for the groups where there are particular points to explain: Volkswagen and its brands, BMW and Mini, Mercedes-Benz, Ford, Stellantis, Toyota and Lexus, and Renault and Dacia. If your make isn't listed, we work on it just the same. ECU remapping from from €200 + VAT (€242 including VAT), in Alcalá de Henares or as a mobile service within the Community of Madrid.
Why some makes have a guide and others don't
When remapping a car, what changes the job isn't the make: it's the engine, the ECU that manages it, how that ECU is protected and which gearbox it has. A Bosch EDC17 is handled in a similar way whether it's in a Seat or a Ford, and the same diesel engine can carry three different badges.
Even so, some manufacturers have quirks that do change what we're going to tell you: modules only they use, their own key systems, gearboxes with the control unit tucked away inside, or engines that aren't worth touching. We've written guides for those. Not for the rest, because a guide that only changed the name of the make wouldn't give you anything.
What sets each group apart
| Group | What's specific to it in its guide |
|---|---|
| VAG Group | Engines and DSG gearboxes shared by five makes, and features that are activated by coding |
| BMW and Mini | Minis with BMW engines since 2014, ECUs that have to be opened and ISN pairing |
| Mercedes-Benz | Sprinter and Vito work vans, gearboxes with the electronics inside and starting system faults |
| Ford | Transit work vans and the AdBlue on EcoBlue engines, which can leave the van unable to start |
| Stellantis | The Peugeot and Citroën BSI, the additive-based particulate filter and the PureTech timing belt |
| Toyota and Lexus | Why remapping a hybrid is almost never worth it, and where it is |
| Renault and Dacia | The hands-free key card and dCi engines that other makes also use |
VAG Group
The same TDI or TSI across five brands, DSG gearboxes with their own control unit and features activated by coding.
BMW and MINI
Shared B-series engines, DME and DDE units that often have to be opened, eight-speed ZF gearboxes and BMW's own coding.
Mercedes-Benz
Sprinter, Vito and cars: CDI engines, 7G and 9G gearboxes with the control unit inside and starting faults specific to the make.
Ford
Working Transits, EcoBlue diesels with AdBlue, EcoBoost petrol engines and Ford's own module configuration.
Stellantis
Peugeot, Citroën, DS, Opel, Fiat and Jeep: the BSI, the additive DPF, the PureTech and the engines they share.
Toyota and Lexus
Why remapping a hybrid is almost never worth it, where it is (Hilux, D-4D) and smart keys.
Renault and Dacia
The hands-free key card, dCi and TCe engines shared with other makes, and the Kangoo, Trafic and Master vans.
The ECU manufacturer matters more than the car manufacturer
Engine ECUs are made by a handful of companies and fitted by almost every make. Knowing which one your vehicle has tells us how it's read, whether it's protected and how risky the job is:
- Bosch: the most widespread in Europe. The EDC17 and MED17 families can in many cases be read through the diagnostic port; the more recent ones, MD1 (diesel) and MG1 (petrol), are protected and often have to be removed or opened.
- Continental (formerly Siemens VDO): the SID families on diesel and Simos on petrol, in European makes and in shared engines.
- Delphi: common on some manufacturers' diesels, with their own reading methods.
- Denso: the usual one on Japanese makes; it generally requires removing the unit.
- Magneti Marelli: very common in the Fiat group and on motorcycles.
When you get in touch, you don't need to know which one it is: we identify it when we read it. But if you've been told your ECU "can't be touched", it's often because it's from a protected generation and needs opening, not because it's impossible. And sometimes it really is, and we'll tell you so.
If your make isn't here
We work on it just the same, whether it's Japanese, Korean, Swedish, British or from anywhere else, and we also do motorcycles and commercial and agricultural vehicles. Many makes without a guide share an engine or ECU with the groups above.
To assess it we need:
- Make, model and year.
- Engine: engine size, fuel and, if you have it, the engine code from the technical data sheet.
- Gearbox type: manual or automatic.
- What you want done: a remap, a fault fixed, a key, a module…
With that we'll tell you whether we can do it, how and the price. If you don't yet know which service you need, start with ECU remapping or ask us for a quote.
Send us the make, model, engine and year. We'll tell you what can be done on your vehicle and the price, before touching anything.
