About remapping
The Fiat Ducato accounts for 1,323 files in our catalogue, with the 2.3 JTD and 2.8 JTD diesels as the core engines, alongside the 3.0 D of the heavier variants. It is one of the most widely used large vans in Europe, and the dominant base for motorhome conversions.
Stage 1 makes up 1,224 files — a strikingly pure performance profile for a commercial vehicle — followed by 158 EGR off. The ECUs range from EDC15 and EDC15C7 on earlier units to EDC16C39, EDC17CP52 and the Magneti Marelli MJ8F3H and MJ9DFH on later ones.

Log in as a professionalFrequently asked questions
Is a remap worthwhile on a motorhome?
Very much so. Motorhomes carry substantial permanent weight, and the extra mid-range torque makes a real difference on gradients and when fully loaded.
Which engine is best covered?
The 2.3 JTD and the 2.8 JTD account for most of the catalogue, with the 3.0 D also present for the heavier variants.
Does it affect reliability?
A well-judged map respects the thermal and pressure margins of the engine. On working vehicles we apply more conservative criteria than on cars.
