About remapping
The Valtra N123 is an agricultural tractor and accounts for 11 files in our catalogue, dominated by the 4.4 litre engine block with a 4.9 litre reference also present. It is a versatile mid-power machine from the Nordic manufacturer.
Stage 1 makes up 9 files, with 3 AdBlue-related files. The ECU is a single reference across the whole catalogue: EDC17CV44. In agriculture we always work to conservative criteria, because the engine spends many hours under constant load.

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.
Can I disable the AdBlue system?
Not on public roads: regulations require emissions systems to be operational. These files exist for specific applications; ask us before ordering anything.
How does this differ from the N163?
The N163 is the higher-power model with the 4.9 litre block. Each has its own entry in our catalogue.
