BMW AIR diagrams show the injectors get power from a similar orange wire from in the electronics box. Both injectors and coils run off 12 volts, so why would this not work? And furthermore, would it prevent the CEL/limp mode issue?

DME will be even more sensitive to seeing an injector not fire I think.
N2MB wants you to cut spark. I can't find any clear answers as to one over the other but some opinions swayed me toward sticking with spark cut. That excess fuel explodes in the exhaust for the anti-lag effect. IF you cut fuel then your car is just misfiring at a set rpm... and could potentially fire with inadequate AFR since spark is still there. blowby gasses/oil or EGR could ignite.
