Yes. Rather easily.

The easiest method is to just set the 'Squirt to stage and then connect the additional injectors to the second injector driver. Then set you stage point to bring them in as appropriate.

As Aaron says it should be fairly easy. Add coil input(rpm), a map sensor and a IAT to the MS and you have a ultra slick add. inj. controller that is temp. compensated. If you look at the MS official forum there is info on how to share sensors(map, IAT,etc.).You also need the correct firmware code loaded that has true "zero" pulse rate ,as some code varients will still inject a min. amount when unused fueling bins are set to zero IIRC.

If you plan to use it as a stand alone FI unit down the road, then you are better off with a V3.The V3 board has one VR circuit built in making it easier and neater to convert the ignition to work along with additional spare pins on the DB37(main connector) available.Otherwise there's nothing wrong with a V2.2.
