You can modify the o2 signal with the FIC but it still does it with the signal bypassed. During cruise there is a pulsing. I can hold the throttle steady in the driveway and it will pulse with the afr wb gauage. Gains rpm as it gets rich, drops as it goes lean. Up and down 100rpm or so with afr's going from ~14 to 16. At idle it's ~13.

AFR's are very steady at start-up until the ecu starts looking at the o2 sensor and while in open loop mode.

.....unless you use a different model.
We sometimes subsitute the 1520 for the 1500. For the most part, we try and stick to the 1500. However, if you wanted to go find one, I think the RU-1500 is a more universal #. They both work the same though.

Is it normal for the afr's to cycle up and down like this? Does this all time when in closed loop mode.

Looks like I need to get the o2 clamp working better. For some reason, the afr's are logged ~0.7 leaner than what's shown on the wb gauge. So hopefully I'm not as lean as what's shown. No pinging heard and no timing retard.
