I'm all for oddball things, but somethings you just need to step back and look at and realize that they just aren't worth the hassle.

I'm sure you get the engine to run, but I see it being severely limited in the way it performs. It'll be a nightmare to tune, dual emulators would help there, which I know works for Nissan applications, but not sure if there's anything special in the XDFs to allow for that, or if you just need to enable the setting in Tuner Pro. I'm still not sure why you wouldn't just try using a single ECM on your engine and see how it runs before complicating things. The magic of oddfire happens in the ICM, not the ECM.
