About remapping
This entry covers the fourth generation of the Fiat Ducato, with 32 files in our catalogue. It is almost entirely the 2.3 diesel in its MultiJet form, the mainstay of the current van and the dominant motorhome base in Europe.
The split is unusual for a Ducato: 18 EGR off and 16 DPF off against 14 Stage 1, plus 7 AdBlue-related files. It reflects a recent generation with full aftertreatment systems. The ECUs are Magneti Marelli MJ9DFH and MJ8F3H.

Why does maintenance lead on this generation?
Being recent, these vans carry full aftertreatment systems that generate frequent consultations. Tampering with them is not permitted on public roads, however.
Do you have Stage 1 for this generation?
Yes, 14 files. Ask us with your vehicle details and we will confirm what is available for your specific unit.
Is a remap worthwhile on a motorhome base?
Very much so. Motorhomes carry substantial permanent weight, and the extra mid-range torque makes a real difference on gradients.
