How does it differ from the Axion?
The Arion sits below the Axion in power. Each range has its own entry in our catalogue.
What do you aim for when remapping a tractor?
Sustained pulling capacity and contained fuel consumption per hour of work, which is what matters on a farm.
Does it affect the machine's warranty?
It may affect the manufacturer's cover. We keep the original file so the work can be reversed if needed.
