I think I got my plx wideband and datalogit working now. Feel free to suggestion changes.
I'm just looking to keep it safe, not max power.

I am only running the leading plugs. Ignore the split timing.

91 views and no comments? Not enough data? Everything looks ok?

If the AFR in your logs is correct, your AFR is borderline lean in the P15 and P16 rows (low 12's). The knock numbers aren't especially high here but you would have a better safety margin if you richened it up some. The easiest way to try and fix this right now would be to

1. turn off O2 feedback in settings 1
2. Perform a "recalc" in the tools menu. This will zero out your INJ map but it doesn't actually change your fueling really
3. Go to your INJ map and highlight the entire P15 and P16 rows
4. change the values in those two rows from 1.00 to some number like 1.05
5. take another log and use the map watch and chart windows to see your AFR in those areas

I disbaled my airpump to get better readings down low. At idle my afr is 12.0-12.1.

I also did a 3rd gear pull on the highway, attached is the log. The highlighted area is where I heard the tap tap or tick tick sound (https://www.rx7club.com/3rd-generation-specific-1993-2002-16/do-i-have-miss-knock-something-else-920302/) I've been trying to figure out.

I tried to record with my camera to capture the sound, but it decided to stop recording. I wonder if the suspension bouncing it around made it shut down? The sound seems to be comming from the driver's side of the engine.

the log looks ok to me. Did you richen up the map a little bit like I suggested?

As for the noise... you need to post a video. But even then there's a good chance that it's just a stupid rattle on a 17 year old car.

I did 2 things:
1) disabled the airpump. I know this doesn't affec higher rpm readings, but the lower range #'s did read better.
2)I changed the setting on my datalog to delta AN1&AN2. I don't think it was set correctly the first time around.

I'll try to get a video of the noise, just makes me nervous that it could be something bad and I just don't know about it.

Questions:
I don't need to be worried that I am running lean, correct?
If the above is true (my afr's are good), do cars produce knock when AFR's are good? I thought knock only occurs in lean situations.
Is it possible for 1 rotor to run really lean (knock) and the other to run normally, and see a good AFR?
If the sound I am hearing was knock and I hear it so clearly, I should see a much higher knock # on my pfc, correct?

captured the sound on video:

Listen for the sound around 6000 rpm.

Sounds like a relay kicking from the video....

Might be more of a electrical problem than engine.

Are there any relays that are supposed to do anything g around 6000 rpm?

This morning I did the idle learn (because my car will surge at stoplights). So here's a new map & log. Map should'nt be much different from the previous, but I wanted to include it.

For the log, I went 1st & 2nd gear WOT.

relay could be AC cutting off or something? Especiialy if you have the power fc relay fix? Not sure what RPM the powerfc cuts the ac off? Was not knock though... knock sounds more like making popcorn in a metal tin pan... lots of faint tinging sounds...

ksu-chewie

iTrader: (14)

it's not the AC relay, that one is much quieter than this sound

how do my AFR's look on my last log?

borderline lean just like the last one

I'll add 5% to 15 & 16 rows like you suggesterd earlier and get another log. thanks!

Added some fuel. How does it look now?

any ideas on the random 110 knock when I'm decelerating?
