Should have posted this a week ago... I put this reply into another post and didn't get any responses, so I started looking at a different route. This is a repost from here:

I can't seem to get my o2 gauge to read anything at my calibration screen...

Soo, I don't want to change anything about my tooth wheel width, since the motor runs great, but that's a different thread.
Just trying to get you guys as much data as I can about this.
the O2 sensor IS heating up.
Initially upon wiring this up, I wired up pins 2 and 4 crossed (read: pin 2 should be disconnected, pin 4 goes to pin 18 on EC18... I had pin 4 disconnected and pin 2 going to pin EC18). This has been fixed.
I thought maybe this had fried my sensor, so I'm now running it with my friend's sensor installed, but i'm having the same issue.
Thanks for any advice you guys may have.
Also... There isn't by chance some output or input I have to enable in order to get my wideband to be recognised?
-----------------------------------------------------------------------------------------------------------------
I got it to recognize an 02 value once in a while... It'll come on after about 45 seconds of VEMS being on, is this just the delay from power on until when the heater is up to temp?
It doesn't show me the o2 value every time, either.
After calibrating it (value of 174 = 20.9), I started the motor, and didn't get a lambda value, or an AFR value. After about 8 seconds I shut the ignition off, and vems showed me a high value of about 1.75 Lambda and 17.0 for AFR... Is there some delay between starting and when it'll show me the values, and I just shut it off right as it gave a value? I'm having some strange issues w all this, lol
When the shadowed peak needles hit 1.75 and 17.0, I had already had vems running for a bit, and I was getting 20.9% on the wbo2 calibration screen, then I closed the calib screen, started the motor, and got nothing on the gauges until after I had shut the motor off in about 5-7 seconds.
Update:
If I run the motor, it'll eventually show me my AFR and Lambda. However, it cuts in and out, seemingly at random.
I'm checking my wiring (again), but aside from that, what could be causing it to cut out like this?
