Question for experienced fast users

[turbobitt]

Can someone tell me what a typical WB O2 gain should be ?? I ran at the track and the WB O2 looked "lazy" and never yeally swinged between rich and lean(always stayed rich). I'm running the gain @ 20% and have 96# injectors . I will also admit that my fuel map is not perfect but would expect the o2 sensor to chase the a/f faster.

Well a wb O2 can just use a linear control scheme, not a ramp/jumpback approach like a NB sensor system would. So you wouldn't expect it to be switching back and forth across rich/lean, especially at the track Ideally the a/f ratio would just go to the target number and stay there with a wb O2. In reality it will have variance around the target number.

O2 never reached desired reading and/or over corrected . Just thought it was lazy and would like input on turning up the gain.

sounds more like it is probably to rich, can you send me a log you saved?
i will look at it

If it never seems to get to the target a/f ratio but isn't maxing out the correction limits, increase the gain. Continue to increase the gain until it seems to be overreacting and then back it off a click.

Just that simple.
