What this service is
What it is
Truck remapping is custom ECU calibration for commercial vehicles — HGV tractor units, rigids and large LCVs. Files are written for torque delivery under load, fuel efficiency at cruise, smoother gear changes on AMTs (I-Shift, OptiCruise, TraXon, AS Tronic, ZF AS) and reduced driver fatigue.
Who it's for
Owner-drivers, small fleets, agri-contractors, plant haulage, refrigerated transport, tipper operators and any business running diesel commercials in South Wales. We tune both modern Euro 6 units and older Euro 5/4 vehicles.
When you need it
When the truck feels lazy on hills, fuel returns are slipping, an AMT is shifting too often, or you simply want to claw back the operating margin a soft factory map is costing you.
Why professional matters
Factory truck calibrations are written for a global market and a worst-case duty cycle. A bespoke file for UK diesel, South Wales topography and your actual loads delivers measurable fuel and driver-comfort gains.
What it costs to ignore it
Truck operating margins are tight. Bad calibration burns money every shift — in fuel, in driver hours, in maintenance and in lost loads.
Our process
Every truck remapping job follows the same disciplined sequence — so the result is predictable, repeatable and guaranteed.
Loads, routes, average speed, fuel data, AMT or manual, driver feedback — we listen before we plug in.
Engine, gearbox, ABS, EBS, DPF and AdBlue systems all scanned. Faults flagged before any flash.
Read out and stored — locally and off-site.
Torque, fuelling, boost control, AMT shift maps and limiters all calibrated for your real-world duty cycle.
We hand over with notes, then check in once you've got real telematics data on the new file.
What you actually get
Verified through your own telematics — not theoretical.
Drivers spend less time in low gears on South Wales valleys and Heads of the Valleys runs.
Reduced shift hunting on I-Shift, OptiCruise, TraXon, AS Tronic and ZF AS gearboxes.
A torquier, calmer engine is a less tiring shift.
ECU swaps, dealer reflashes — we re-apply your file at no extra charge.
Yard visits early morning, late evening or weekends to minimise downtime.
The detail
Truck tuning is a different discipline to car tuning. Here's what's specific and what to demand from anyone working on your commercial vehicles.
Scania (DC09, DC13, DC16), DAF (MX-11, MX-13, PACCAR), Volvo (D11, D13, D16), MAN (D26, D38), Mercedes Actros (OM471, OM473), Iveco Cursor 9/11/13, plus large LCVs (Mercedes Sprinter, Iveco Daily, Ford Transit, VW Crafter). Both Euro 5 and Euro 6 supported.
Torque map by gear and load, fuel rail pressure, injection timing and duration, boost target, AdBlue dosing strategy, EGR control where present, AMT shift point and pressure maps, idle speed under PTO, and cruise control responsiveness. Emissions strategy stays intact.
Modern HGV gearboxes are deeply ECU-coordinated. Raise engine torque without refining the gearbox map and you'll get harsh, frequent shifts. We calibrate both sides — engine and gearbox — so the truck feels factory-smooth at the higher output.
It's illegal under the Construction & Use regulations, it's an MOT failure, it carries fleet operator liability, and it generates O-licence risk. Any tuner offering 'AdBlue delete' on a road-going UK truck is exposing your operation to serious legal trouble.
Yard visits across the South Wales valleys and M4 corridor. We'll travel further for fleet jobs — call to discuss your operation.
