83SC CO Value w/o O2 Sensor
I'm getting ready to adjust the CO setting. The Bentley manual says to use .6-.8%. However, I'm not using the O2 sensor. Should it be more like 2.5-3.0%?

Is this a US or ROW SC? I ask because if you have the sensor unplugged, and you still have a frequency valve this is going to be an issue.

Just a suggestion, of course you can go 3% route and be just fine, however I have a nice dyno sheet showing better AFR's with the sensor hooked up and the CO around .8%. Just something to consider, other wise go with the 3% and leave it disconnected.

Ok. I set it at .8% and hooked the O2 sensor back up. Let's see how it does.
