“H17 achieved close to a 10% saving on fuel consumption. H18 achieved almost 20%. I would definitely recommend this mapping to any transporter, especially with rising fuel costs.”

How eco tuning works
Eco tuning is not about chasing maximum power. It is about improving the working area of the engine so a loaded truck can maintain momentum with less throttle and fewer unnecessary gear changes.
One of our strongest truck services
Modern emissions systems can become a major operating liability when trucks work long distances, carry heavy loads and operate far from specialist support. A blocked DPF, failed NOx sensor or AdBlue dosing fault can place a truck into derate, limp mode or a no-start countdown—even when the engine itself is mechanically healthy.
DPF and AdBlue systems are not universally required across every truck in Namibia and South Africa in the same way as newer European markets. For suitable vehicles, professional removal can eliminate the recurring system faults, reduce repair exposure and prevent avoidable downtime caused by emissions components that are not essential to the truck's core mechanical operation.
Permanent software calibration for suitable trucks, coordinated with the required professional hardware work.
A complete software solution for suitable trucks suffering from unreliable SCR and AdBlue systems.
Every truck is assessed individually. Roadworthiness, excessive-smoke rules, warranty conditions and any cross-border or contractual requirements remain the owner's responsibility and should be considered before removal.
A measurable fleet process
Record comparable kilometres, payload, route, idle time and fuel use before tuning.
Scan the truck, discuss faults and confirm whether its mechanical condition is suitable.
Install a truck-specific economy map built around the engine, gearbox and duty cycle.
Log comparable post-tune data and calculate the result over a meaningful operating period.
Use the measured result to decide how and when to tune the remaining vehicles.
Truck tuning FAQ
Everything most fleet owners need to know before requesting an assessment.
Truck eco tuning is an ECU calibration focused on efficient torque delivery under real working load. The aim is easier pull-away, fewer unnecessary gear changes, better loaded drivability and lower fuel use where the route and driving style allow it.
There is no honest fixed percentage for every truck. Route, payload, driver behaviour, gearing, tyres, wind and mechanical condition all matter. We use 5% as a conservative planning example and recommend comparing properly logged before-and-after data under similar operating conditions.
No. A good economy calibration normally improves usable torque in the working RPM range so the truck can maintain momentum with less throttle and fewer shifts. It is not a speed-limiting or under-powering exercise.
Yes. The best approach is to establish a baseline, tune one or two representative vehicles, log comparable routes and loads, and then plan the wider fleet rollout from measured results.
Common causes include interrupted regeneration, soot loading, failed temperature or pressure sensors, NOx sensor faults, AdBlue crystallisation, dosing faults and poor-quality fluid. The result can be warning lights, derating, limp mode or a no-start countdown on some vehicles.
Yes. DPF removal and AdBlue/SCR removal are two of our strongest truck services. They can provide a permanent solution to recurring regeneration failures, sensor faults, crystallisation, dosing problems, derating and no-start countdowns. We diagnose the truck first, complete the required software calibration professionally and discuss the correct hardware work for the specific vehicle. The truck's intended use, roadworthiness and cross-border requirements must still be considered.
It should not produce excessive smoke. Economy tuning is about using fuel more efficiently, not adding uncontrolled fuel. Existing injector, turbo, intake, boost-leak or engine-condition problems must be corrected first.
