Mercedes Sprinter ECU Remap South Wales

The Mercedes Sprinter is the workhorse of South Wales — and an economy remap is one of the best investments a Sprinter operator can make. More torque when loaded, better MPG on the motorway, and a smoother drive every day.

Mercedes Sprinter Remap Results

The OM654 2.0D diesel is Mercedes' latest generation unit, fitted across Sprinter variants from 114hp to 190hp. The 143hp version shares hardware with higher-output variants — a remap safely realigns the output to match.

A Stage 1 remap requires no hardware modifications. Our specialist software recalibrates boost, fuelling and ignition timing within the engine’s safe limits, delivering instant, driveable gains.

What a Remap Actually Does

Boost, fuelling and injection timing are recalibrated on the OM654. The torque increase is most valuable when the Sprinter is fully loaded — it pulls out of junctions and up motorway sliproads with noticeably less effort.

01

Boost Pressure

Factory boost is set conservatively. We raise it to the level the turbo and internals can comfortably sustain, unlocking power that was always there.

02

Fuelling Map

Fuel delivery is recalibrated to match new boost levels precisely — giving a cleaner burn, better response and improved efficiency under light loads.

03

Ignition Timing

Timing is advanced where the engine can safely benefit, improving combustion efficiency and delivering more torque across the full rev range.

04

Throttle Response

The factory throttle map is deliberately muted. We sharpen it so the car responds the moment you press the pedal — no lag, no hesitation.
