About remapping
This Scania entry covers the 420 hp rating across the P, R and T cabs, with 25 files in our catalogue. It spans three versions of the 12 litre six-cylinder diesel: pump-duse, HPI and HPI-TC. It is a haulage tractor unit configuration widely used on national and international routes.
Stage 1 accounts for all 25 files, with 2 Stage 2 alongside — a completely clean profile with no maintenance work at all. The ECU is a single reference across the whole group: EMS S6.

What is the difference between pump-duse and HPI?
They are two different injection systems Scania used in this era. Both appear in our catalogue for this rating, and each is worked on its own terms.
Is it worthwhile at 420 hp?
Yes. What is gained is not headline power but sustained torque, which on gradients with a full load means fewer changes down.
Does it affect fuel consumption?
Worked properly, it tends to reduce consumption per hundred kilometres on the same route, because the engine works less hard for the same job.
