There are no problems with staging. However, since this is designed for a 2 port engine you would need to make the MS2 modifications needed to add the 2 additional injector channels. Staging uses channels 1+3 and 2+4.

No news about fuel consumption code?

if any help for you to check the code, I've now scoped more thoroughly the timings and pulse widths of injection & ignition signals. As you mentioned, the injection method is not "supported" on a V2-motor, but it seems there are only two things to adjust:

Cylinder#1: the injection timing degrees diagram image to follow is the "4.1.3 Sequential/Semi-sequential Timing" (and not the "Siamese-port Timing" despite the "Sequential Siamese" with "Dual Values" -method is selected).

Cylinder#2: same diagram image above, but the base point (0 deg) has to shifted amount of degrees defined on the "Oddfire First Angle" field

Otherwise all just perfect - engine idling better than ever before :)

Thanks Guys!

Isn't that what it is supposed to do? Is this a question or a comment?

It's a comment and I'm thinking here of V2-engine builders (willing to oddfire & sequential injection) and if it's possible to clarify, either instructions & code or perhaps only highlight on the documentation?

For myself it was quite challenging (I think without scope impossible) to understand the timing degrees and base point, especially on the Bank#2.
