Agriculture · TractorsEngine remapping for tractors and agricultural machinery
A tractor does not drive to Nivelles. That is why we travel out: to the farm, the shed, the depot or the field edge, in Belgium and in the neighbouring border regions. Powerconcept has been developing engine maps since 1995 and measures its results on its own dyno.
What we do, and who for
We work for farmers, agricultural contractors, cooperatives and dealers. The job is to read the engine ECU, save the factory file, develop a map for that specific engine, then write it back and check how it behaves. We work on injection, boost pressure and torque management, never on the emission control systems.
Moving a tractor or a combine costs more than the work itself, and during the season it is simply not possible. So we come to you, on the farm, at the depot or on site, in Belgium and in the neighbouring border regions: reading and writing happen on the spot.
An agricultural machine does not fit on a roller dyno built for cars. Validation is done through electronic readings before and after, checks on pressures and temperatures, then a loaded test in real work. The Nivelles dyno remains central to the method for development work.

- Factory file saved and archived: the work stays reversible
- Aimed at torque and fuel use per task, not peak power
- Named invoice and intervention report
What an agricultural map actually changes
Our development database, the one our configurator queries, holds 1,695 agricultural engine variants across 18 brands. These are development values, not a promise for your machine.
In Stage 1, the median of our database is 24 % more power. Nine variants out of ten fall between 10 and 36 %. On torque, the median is 20 %, calculated on the 1,352 variants that actually gain any.
That precision is not a flourish. On 315 variants in our database, the stated torque does not change although power rises. The reason is mechanical: torque is often capped upstream by the transmission, the axle or the power take-off, and a serious map does not force that ceiling. The gain is then taken in the upper part of the working range, as revs held and power available for longer, rather than in peak torque. It looks less impressive on a spec sheet, and it is what keeps a gearbox alive.
In the field, what farmers describe is a machine that holds its revs as the load builds and fewer downshifts at the headland. On fuel, the lever exists provided the gain is not turned into forward speed: at the same load and speed, an engine working lower in the rev range uses less.
Our database holds no Stage 2 data for agricultural machinery. We therefore put no Stage 2 figures on this page.
How the work is carried out
It starts with a diagnostic: electronic reading of the machine, a check that no fault codes are stored, condition of the turbo, the injection system and the emission control line. A machine with a fault gets repaired before it gets remapped.
The software is read through the diagnostic socket when the ECU allows it. Otherwise it is read on the ECU, on the bench, which means removing it. That is what weighs most on downtime: we check your part number before fixing a slot, and the season is part of the conversation.
Then comes development: injection, boost pressure and permissible torque tables are changed in progressive steps, keeping the ECU protections active and respecting the transmission ceiling. The file is written back to the machine, then checked through electronic readings and a loaded test.
Every agricultural job is quoted individually: the brand, the generation, the reading method, the number of machines and the location all change the actual work.
The agricultural brands we work on
Eighteen manufacturers appear in our off-road database, with the original values and the values targeted in Stage 1.
- John Deere, Case IH and New Holland: the three best covered brands, tractors and combines.
- Claas and Fendt: tractors, foragers and harvesting machinery.
- Massey Ferguson, Valtra and Challenger.
- Deutz, Same, Lamborghini tractors, Steyr, Mc Cormick and Lindner.
- Krone: self-propelled harvesting machinery.
- Caterpillar, JCB and Hitachi belong rather to our construction machinery page.
Your machine is not listed? It is simply not in our database yet, which does not mean it is impossible. Describe your machinery to us and we will tell you what data we hold.
What we do not do, and why
At Powerconcept we neither remove nor disable any emission control system. No particulate filter, no EGR valve, no AdBlue, and the fact that a machine never uses a public road changes nothing. This is not a commercial stance, it is the law, and it is also what protects the resale value of your machinery.
We do not fit tuning boxes either. A box sits between the sensors and the ECU and feeds it falsified values: the engine then works outside its own tables and protections. On an engine running hundreds of hours at near constant load, that is what to avoid.
We do, on the other hand, diagnose and repair SCR faults, the leading cause of downtime on a recent machine in the middle of the season. Urea quality sensor, pump, injector, crystallised fluid, a fault logged by the ECU, then engine derating: that derating cuts available power and eventually prevents starting. Our job is to identify the failed part, replace it and bring the system back into working order with fluid that meets the standard. We are describing a repair method, not a guaranteed outcome: the real state of the system is established by the diagnostic.
Our rule fits in one sentence, and it has not changed since 1995: we work on engine calibration, never on what protects the air we breathe. DPF, EGR valve and AdBlue: where we stand
Frequently asked questions about tractor remapping
Does a remap void the agricultural manufacturer's warranty?
It does not void it automatically, but it can be held against you: a manufacturer may refuse to cover a part it considers to have failed because of the modification, usually engine and transmission. The rest remains. We keep your factory file, and the original map can be written back before a dealer visit.
Do you remove AdBlue, the DPF or the EGR valve on a tractor?
No, never. The fact that a machine works off the road changes nothing: we neither remove nor disable any emission control system. We do diagnose and repair SCR faults, which are the real reason the question gets asked.
My machine is derated by an AdBlue fault: can you help?
Yes, by repairing it. Derating is the ECU's normal reaction to an SCR fault: it cuts power, and eventually blocks starting. We read the fault codes to identify the part at fault, replace it and bring the system back into service with compliant fluid. What we will not do is silence the fault and leave the system out of action.
Wouldn't a tuning box be simpler on a tractor?
Simpler to fit, yes. Safer, no. The box falsifies the signals the ECU receives, so the engine works outside its tables and protections, precisely where an agricultural transmission is under most strain. Tuning box or remapping
Why does torque not rise on some machines?
Because it is already capped upstream. On 315 variants in our database, power rises without the stated torque changing: the transmission, the axle or the power take-off set a limit we do not force. The gain is then taken as revs held and power available for longer. We prefer to say so rather than dress it up as a percentage.
How much fuel can be saved?
We do not put a figure on it, because it depends on the work being done. The lever is known: torque available lower in the rev range lets a gear be held longer and keeps the engine in its efficient range. If the gain is turned into forward speed, hourly consumption does not move, but the job advances faster.
Do you travel to the farm?
Yes, and that is the normal case. A tractor does not drive to Nivelles: we work on the farm, at the depot or on site, in Belgium and in the neighbouring border regions. The location is part of the quote, and we take the season into account when planning.
Can you remap a machine more than ten years old?
Yes, if the mechanics are sound. Hours matter less than the real condition: stored fault codes, state of the turbo, the injectors and the transmission. An engine using oil gets dealt with first, and the preliminary diagnostic is there to say so.
