Scania R420 ECU remapping
17 files available
About remapping
This Scania entry covers the 420 hp rating of the R cab, with 17 files in our catalogue, spread across the 11.7 and 12 litre blocks including an HPI six-cylinder variant, with a 580 reference also present. It is a common long-distance haulage configuration.
Stage 1 makes up 14 files, with 4 AdBlue-related files. The ECUs are EMS S6, EMS7 and MS6.2. On heavy vehicles we always work to conservative criteria, because the engine spends its life under load.

How does this differ from the P-R-T 420 entry?
This group covers units recorded specifically with the R cab. If your vehicle carries a different cab, it is worth checking that entry too.
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.
