Volkswagen T4 ECU remapping

About remapping
The Volkswagen T4 Transporter accounts for 31 files in our catalogue, dominated by the 2.5 TDI five-cylinder, with the VR6 petrol also present. It is the generation that established the Transporter as a camper base across Europe.
Stage 1 makes up 19 files, with 8 Stage 2 and 4 Stage 3 — an unusually high showing at the upper levels, reflecting how much this generation is modified by enthusiasts. The ECUs include EDC15, EDC15+ and EDC15VM on the diesels, plus ME7.1 on the VR6.

Why so much Stage 2 and Stage 3 work?
The T4 has a strong camper and enthusiast following, so many vans arrive with turbo, intercooler or injection modifications already fitted.
Is a remap worthwhile on a camper of this age?
It depends on engine condition. On a well-maintained 2.5 TDI the extra torque makes a real difference on gradients with a loaded camper.
Do you work with EDC15 ECUs?
Yes, they are standard on this generation and fully covered in our catalogue.
