There is nothing wrong with running the 0411 in an app like this. With the conversions we do, off road race rigs, jet boats, agg........ Its all the same. If you are wanting to simplify things more that's where the custom OS comes in.
Case in point.... Rig we just wired and tuned. No transmission but a hydraulic pump instead. Everything is air or hydro driven. This was with an E38 too. LOL
