EGOR Output Signal Survey

[Kooser, Jacob]

It is a heated 02 sensor, so I don't know what difference, if any, that
would make.  The VW carb wasn't a "proper" Weber, but one of the Holley /
Weber "progressive" 32/36 millimeter throat carbs.  Think of a baby 4-barrel
sawed in half, and they're known for being a bitch to tune correctly.  The
quadrajet is just a plain ol' q-jet.  No ccc for me me me.

To big issues here:
First most carbs have maybe 4 different circuits,  so often the AFR is
really wondering around alot.
The oem O2 sensor is basically a switching type sensor so it will swing alot
as a matter of just some AFR change.

A proper;ly done Weber will move around alot less then a feedback CCC Q-Jet
