About remapping
The JCB Fastrac is a high-speed agricultural tractor and accounts for 14 files in our catalogue, spread across the 6.0, 6.6, 6.7, 7.4, 8.4 and 8.5 litre engine blocks. It is unusual in being designed for genuine road speed as well as field work.
Stage 1 makes up 13 files — a very clean profile — with 3 AdBlue-related files. The ECUs include EDC17CV41, EDC17CV44 and Cummins CM850 and CM554 references. In agriculture we always work to conservative criteria.

What do you aim for on a Fastrac?
Sustained pulling capacity in the field and contained fuel consumption on the road, since this machine does both jobs.
What are the Cummins CM ECUs?
They are Cummins engine control units, used where the machine carries that engine family. They appear identified in our catalogue.
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.
