The Peugeot Boxer shares its platform, engine and drivetrain with the Fiat Ducato, making it equally responsive to professional ECU remapping. At Bob's Mechanical Repairs in Birnam, Perthshire, we remap Boxer campervans and motorhomes for owners across Scotland who want better hill climbing, improved fuel economy and a more enjoyable touring experience. The Boxer's 2.2 BlueHDi diesel engine is fundamentally the same unit as the Ducato's 2.3 Multijet — both are products of the Stellantis (formerly PSA-Fiat) commercial vehicle partnership. This means the tuning potential, safety margins and expected results are identical. Motorhome manufacturers like Auto-Sleepers, Elddis, Bailey and Swift commonly use the Boxer as their base vehicle, and we've remapped examples from all major converters. A fully loaded Boxer motorhome or campervan can weigh 3,500 kg or more. The standard engine calibration, designed for a lightweight panel van, simply isn't optimised for this level of loading. Our motorhome-specific remaps address this directly, calibrating the engine for the real-world weight it carries. The improvements are dramatic, particularly for the lower-powered 120 and 140 bhp variants. Scottish hills that previously required second or third gear can be climbed in a higher gear. Motorway cruising becomes relaxed rather than strained. And fuel economy improves because the engine is working more efficiently rather than constantly at maximum effort.
