Correct O2clamp voltage?
Hi Mturbo.netters,
I just am a bit confused about the correct O2clamp voltage. I have my clamp dialed at 0.38 V at the moment which I read in here should be fine. Over at the mx5nutz forum there is a discussion at the moment about the EMU and the AFRs where a clamping voltage of 0.50 v to 0.47 v (stoich) is proposed.
Could you please try to explain the correct setting for me?
Thanks

Thanks Zaphod for posing and Olderguy for answering this question. I was getting very frustrated with my recent BRP62 supercharger (sorry) installation. There was lots of stumbling at boost transition and/or from closed to open loop. Both felt like over rich but I'd been blinded by the lean ping at WOT caused by last winter's 91 octane gas into thinking it had to be a lean problem.
I fixed the ping with colder plugs and 94 octane. Setting the O2 clamp at 0.38v (from the, as received, 0.33v) fixed the stumble.
