Torque-focused remapping
Heavy vehicles need usable torque in the real operating range, especially loaded or towing. Calibrations target in-gear pull, not headline figures.
Commercial vehicles
HGV and truck tuning for torque, economy and uptime
HGV and truck tuning for torque delivery, fuel economy and reliability, with DPF and AdBlue diagnostics and a disciplined tuning file workflow for working vehicles.
Commercial vehicles
Calibrated for the way the truck actually works
A working truck earns nothing standing still. HGV tuning here is about practical gains: stronger torque delivery where the engine actually operates, calmer loaded driving and fuel economy that shows up at the end of the month — with diagnostics handled before any file decision is made.
Fleet fuel economy files
Economy calibrations aim at measurable running-cost reduction while keeping every unit inside safe operating limits.
DPF and AdBlue diagnostics
Emissions-system faults get a proper diagnostic route first. Tuning is never used to paper over a mechanical problem.
Scheduled around the work
File reads, calibration and write-back are planned around the vehicle's schedule, and the original file is archived for every unit in the fleet.
How it works
From quote to road in four steps
Read the ECU file
The original file is read from the vehicle and archived before any modified file is written.
Build the calibration
The tuning file is prepared for the exact engine, hardware and requested route — performance, economy or diagnostics-led.
Check against stock
The modified calibration is compared with the original file before it goes anywhere near the vehicle.
Write and road check
The file is written back, the vehicle is checked under real conditions and handed over with a clear record of what changed.
Tuning files are managed through the TuningBay portal — the same professional workflow used by dedicated file services.
