What does an FH12 gain from a remap?
Fuller torque at low revs and, in many fleets, a more contained average fuel consumption over high annual mileage.
How does it differ from the FH13?
The FH12 is the previous generation with a 12-litre block; the FH13 uses a 13-litre unit. Both are covered in our catalogue.
Does it affect engine life?
On commercial vehicles we work to more conservative criteria precisely because the engine accumulates far more hours than a car engine.
