Hi guys,
I've brought this up previously but still couldn't figure it out. no matter what i do to my maf curve i cannot tune out this repetitive lean area. Below is just one example throughout the log that this happens. I noticed that it seems like the 02 sensors aren't switching fast enough..every time this lean condition happens there is a large gap from when the o2 voltages switch. I've tried messing with the 02 sensor settings (proportional/integral delay) with limited amounts of success. Is there any other 02 sensor setting that i could try and adjust to get rid of that large delay that i'm seeing. In this log i actually cut the delay down by 30% and you can see right after that lean area the o2s start switching really fast (almost too fast). i'm leaning towards 02 sensor settings, but i just can't figure out what i need to adjust to correct the problem. I don't have headers so i didn't think i needed to adjust the 02 sensor settings at all. Any other input on this would be appreciated.
