The VSS is the same across all the D-series, B-Series and H series transmissions.

How did you get your engine to run in lean burn mode given it's an HX not a VX lump? I don't recall the HX having EGR or vtec-e that made the VX engine so efficient. I've left the honda world a while ago but I always wanted to machine a VX head to accept GDI injectors then see if I couldn't rig up lean burn with stratified running mode. Hard to say if the power loss from running the HP pump would offset the gains in efficiency.
