If it's not really about tuning or wiring. Then it belongs in here.

This is something I'd thought about in the past but never got around to digging too much into - I figured that there would be too many electronic nannies to wrangle to make it work. But now that I've seen it done I want to think about it again.

From the video(s), it sounds like he's using a Syvecs ECU, stock TCM/TCU with an EcuTek flash, and I assume some form of the AWD controller, likely one of the modified/upgradable ones.

Does anyone here have more information about how this is all made to play nice? I'm going to spend some time combing through wiring diagrams to see what I can figure out on my own, as my internet sleuthing has turned up basically nil.
