Yes i understand. It's only because most standalones don't have provisions for the heater as its a waste of a pinout. When I asked about running off the wideband I was asking if he was running closed loop all the time or the same setting all the time. Sorry.. was a fast post from my phone.

I know that for my ecu there's an rpm dependent gain for closed loop. I'd assume the vipec would have a similar setting.

Yeah a front o2 would make tuning tip in a bit and decel a lot faster and more accurate too.
