I'm trying to tune my first MAF on a Gen 3. This is how I have the graph setup but it doesn't populate anything when logging. I searched and found several threads about it and they all appear to be set up similarly to how mine is. Can anyone help?

Hm, that's frustrating. I'm glad you noticed that. I know with 100% certainty that both Commanded AFR and EQ were in the channels when I started. (They're in the config file I posted in my OP.) I don't know why they're not in the log. I don't recall deleting them before the log. But I will go back and log again with them there, see what happens. Thanks for noticing it.
The channel list in your log is very different from your screenshot. I have had a seemingly random channel list load up without noticing it before. I honestly have no idea if I just forgot I was working on something else, or if some glitch was to blame. It happens.
I noticed that as well. Weird.
I loaded the above channel list again today and it worked. Thank you.
Actually, I just read the log again. AFR Err was working, but EQ still wasn't.
Don't use AFR, use EQ. Pretend you never heard of AFR.
Equivalence Ratio Commanded is working just fine when I open that log and scroll through.
If you want 'EQ Ratio Error', then BOTH the commanded EQ and the wideband have to be giving the same type of number. You can't have Commanded EQ vs WB AFR.
