Any SG peeps here that can confirm or debunk?

Thanks, after some google it does look like the civic shuts the injectors off completely (and the 2007 apparently has quirk, delay engaging them again?).
I have experience mapping bikes / "high performance" engines, and we'd definitely never completely remove fuel, but with tighter emissions standards it makes sense I guess. Would be interesting to know exactly how the engines can get away with it.
