Stage 1 accounts for all 11 files — a completely clean profile with no maintenance work at all. The ECUs are John Deere's own references: L4, L9/L11/L12, L11, LX and LXX. In agriculture we always work to conservative criteria.

How does this differ from the 6420?
They belong to the same 6020 series but use larger engine blocks at higher output. Each 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.
