Why would you use deadtime to tune ethanol percent? Deadtime is to tune to your specific injector, not fuel type or blend; that's what injector size compensation is for (besides for actual injector size and base fuel pressure). If ethanol % really is messing up your tune, it will change it at WOT too, not just idle. Deadtime has the largest effect at the lowest IPW's.
If you use closed loop like stock (I don't, I run open loop all the time), then it shouldn't even matter anyways as the ECU will correct it.
