air-fuel and knock

[Hoffman Anthony J A1C 552 CMS/MXMVC]

We just installed one on a 1993 VW Fox, and it was VERY helpful in setting
the mixture after installing a big cam. We already did the 4-wire F150 O2
sensor, and installing it was easy. Without it, we had the car running way
too rich, and couldn't get it to idle below 1300 RPM. It also pointed out a
problem with the car we wouldn't have found without it. The car goes full
lean in the middle of throttle, then back to where it belongs at full. Bad
throttle pos. sensor. In short, they are helpful to a certain extent. When
you get serious and shell out the $$$ for EFI on a 10VT, I'd also go with
the wideband. Until then, the gauges work pretty well. As for just hooking
up a meter, I have a $250 Fluke meter, and it doesn't read fast enough.
Trust me, I've tried it.

Intended vehicle is 5cyl Audi, either NA or turbo.

Does anyone have any experience with add on air-fuel ratio gauges, such as
autometer, edelbrock, s-w? Are they accurate enough to be safe?

Is there any way to monitor knock sensor activity? Besides waiting for a
stored code.
