In short (TL;DR)
- What it is: adapting the engine control unit (ECU) software of a truck or tractor unit for higher torque and better response.
- What we do: the software work only. We do not do mechanical work and do not touch the tachograph or the mandatory speed limiter.
- Price: from €300. The final price depends on the engine and the ECU.
- For what: trucks, tractor units and other freight vehicles with a programmable ECU. Not every model is supported – we check before the work.
- Limits: the clutch, gearbox, turbocharger and cooling must withstand the higher load.
- Legal position: a power increase may not match the type approval and may affect insurance, warranty or leasing terms. Before the work we recommend informing your insurer and, if applicable, the leasing company.
Truck and tractor unit power increase means adapting the engine control software at ECU level. Fuel delivery, boost pressure and other parameters are changed so that the engine makes better use of its potential.
What changes and what does not
| Changed | Not changed |
|---|---|
| The engine control software (fuel delivery, boost pressure, torque curve) | The tachograph and its data |
| Throttle response | The mandatory speed limiter |
| Torque distribution across engine speed | Mechanical parts (turbocharger, clutch, gearbox) – we do not change them |
What must be assessed before the work
- Clutch and gearbox. Higher torque loads the transmission. Trucks usually work under heavy loads, so we discuss the limits in advance.
- Turbocharger and cooling. A higher load means a higher exhaust gas temperature and a greater cooling demand.
- Technical condition. Software does not remove mechanical defects – if the engine or fuel system is worn, the result will be poor and the risk higher.
- Use. Different driving (full load, mountains or city) needs different software emphasis.
What we do not promise
We do not promise a specific power or torque gain in advance: it depends on the engine and the conditions. We do not promise lower fuel consumption either. Before the work we tell you what result can reasonably be expected.
Price
Truck and tractor unit power increase costs from €300. We give the exact price after checking the model, engine and ECU. You will find similar services for other machinery on the pages about agricultural machinery and quad and motorcycle power increase.
Frequently asked questions
Does it suit my truck?
It depends on the model, the engine and the ECU type. Before the work we check whether the software can be read and changed. If the model is not supported, we do not start.
How much power will you add?
We do not promise a specific number – it depends on the engine and the conditions. Before the work we tell you what gain can reasonably be expected in your engine.
Will the tachograph or the speed limiter be affected?
No. We do not touch the tachograph or the mandatory speed limiter.
Can the factory software be restored?
Yes. Before the work we save the original ECU software.
Do I need to inform my insurer or leasing company?
Yes, we recommend it. A power increase is a modification of the vehicle that can affect insurance, warranty and leasing terms.
Do you do EGR, DPF or AdBlue work for trucks?
Such work for trucks is assessed individually. Contact us and describe the model and the problem – we will tell you whether we can help.
