My closed loop O2 readings are going from 14.0 to about 15.5...I would like to tighten them up a bit. BLM numbers are good, 128 +/- about 5. Prop gains? I'm not sure how to tighten these up. Running EBL Flash, Zeitronix ZT-2 WB simulating NB O2.

I don't know if this helps but I played around with the gains quite a bit. End result was that I gave up and went back to running the ECM off of the WBO2.

The problem I had was from NBO2 temperature changes. It varied so much that I was always changing the gains to correct for it.

How accurate is the NBO2 reading from the WBO2 sensor you are using? If I use the direct WBO2 reading for the closed loop (with code change) everything works great. The simulated NBO2 reading doesn't work that well.

 

my NB O2 was really weird...I even had a 3 wire and it still gave me issues. Since I bought the WB, I've been using it with consistent readings.

I just spliced the WB's output into the purple wire in the harness.

 

so, will reducing prop gains tighten up the AFR?
