John Deere S660 ECU remapping
27 files available
About remapping
The John Deere S660 is a combine harvester and accounts for 27 files in our catalogue, entirely the 9.0 litre diesel block. It is a high-capacity machine for large-scale grain harvesting.
Stage 1 makes up 26 files — a very clean profile — with 3 EGR off and 2 Stage 2. The ECUs are John Deere's own references: L14/L15, L15, L23, L14, L15/L16 and LXX. In agriculture we always work to conservative criteria, because the engine spends many hours under constant load.

What do you aim for on a combine harvester?
Sustained capacity under load during the harvest window, when the machine works long hours without margin for stoppages.
Is it different from remapping a tractor?
The criteria are similar but the working profile differs: a combine runs at near-constant load for extended sessions, so we are especially conservative.
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.
