Recently put another O2 sensor bung in the exhaust pipe after the system mods to get the new muffler in last winter. I want to put the O2 sensor in there before the next track day, but I'm seeing some confusing things on the display. I looked at the Innovate website, but didn't see anything helpful, so I thought I'd post my questions here first before registering on their site.
I followed the directions in the quick start guide for initial calibration (I've used the unit before, but thought I'd do another calibration before this installation), but the display numbers look off. The O2 display says 19.1% (isn't atmospheric oxygen around 21% by weight?), and the lambda readout says 11.7 while the sensor is sitting in open air. Obviously I don't have a rich mixture in free air (so it can't be 11.7:1 A/F), so does this 11.7 number mean 11.7 times leaner than "normal" combustion byproducts at the usual 14.7 A/F ratio? Just trying to make sense of stuff so I can trust the readout when I'm on the track.
If someone can help me out I'd certainly appreciate it.
Thanks,
Mike
