Part of our R&D for building out a MoTeC solution for this platform involves mapping & characterizing the D/I injectors (relatively easy) and the D/I fuel pump (much more complex). Here's a little sneak peak at the D/I pumps (yes plural).
Pictured is the non-Si D/I pump. It is a little different externally and internally vs the Si pump.
Next is the intake cam, that also drives the D/I pump via 4 lobes. This is also the non-Si cam.
The Si cam & pump are on order so I can take the pumps apart and compare them internally -- but so far what we believe is the Si pump will deliver a higher volume of fuel over the non-Si pump. The intake cam has a higher lobe profile for the D/I pump and should deliver more fuel.
No you cannot just swap the Si cam & D/I pump into a non-Si. There are software changes in how the pump is run (something we've already been digging into with @KTuner).
