How to utlilize a WB O2
How to utlilize a WB O2
As we all know, performance/HP is the bottom line. A reading on a gauge does not equate to max performance. I would like to hear from those that use a WB O2.
How does the WB O2 enhance the tuning process?
Its very clear that we should start rich in our calibrations and tune towards max mph/hp. Where does the WB come into play in this senario? In my mind its clear that as you descend from a very rich condition you will approach a point where the engine makes max power. Any leaner and performance drops off. Where in this tuning process do I use the WB O2?
Assume we have observed the plugs and are not in detonation.

I then have a section of road that I can use for testing. With my VSS display I can tell if my *trap speeds* are going up or down per a given pass.
So make a pass and try richer.
The neat part part was that in just a few passes I could:
a) tell where I was to start.
b) how much of change was needed to make a noticeable change.
c) was able to actually comfirm my correction was rich or lean, and how much so.
In four short passes, the other day I was able to do what normally would take a whole evening at the drags, and found out what my engine liked. Now, I can go thru and map out more of the calibration, since it's a WB I can set say lean cruise to 16.1:1 or 16.7:1 with out a bunch of plug readings.
