ECMlink Need tuning criticism and knock troubles

[HooKnBooK]

I think this is my problem. I forgot that I had custom downpipe made to accommodate my vband hot side. Then just put the wide band in. Meaning I have nothing else monitoring. So hopefully if I put an o2 sensor near the wide band it should fix things?

I see...that is useful information. That would explain why the front o2 mimics the raw wb voltage, in terms of frequency.

So hopefully if I put an o2 sensor near the wide band it should fix things?

You can run nb sim off of the wb alone, but as calan said - it is improperly configured.

your WB is not logging properly; it looks like it's switching between two hard values, instead of outputting an analog representation of the AFR.

This.

That is what confuses me. I set the switch point to 2.34 and it didn't change anything. Do I need to adjust STFT rates? I can't remember if I adjusted the o2 feedback yet

 

[Calan]

Since he is running a wb in the rear o2, shouldn't he just leave the closed loop work to the front o2 (NB) and ditch the narrowband sim all together?

That's what I would do.

I'm still chasing my tail. I saw that my simulation drop down bar was set to rear instead of front. I switched it to front and this is what's happening? I'm thinking about just taking the downpipe off and just adding an o2 sensor back to it. I don't understand what I'm doing wrong. I haven't messed with the o2feedbackadj yet

Prosport wideband in front o2
No rear o2

Your wideband is still acting weird.

Just hook a factory front O2 sensor back up so you can get started. Put the WB back in the rear O2 location, and work on getting it to log correctly as time permits.

Could you clarify what you mean by "acting weird"? My log is matching my wideband. I just can't get the simulation to work. But I'm just going to put the o2 sensor near the wideband

It doesn't look like a typical WB signal, and it varies by only .03 (16.57 to 16.61) over a 14 second period while idling. That's not possible, as far as I know.

Why not just put a factory O2 sensor back in the factory location?

Hmm. I guess I'll have to look into it after I put the o2 sensor in.
I would if I could, but I had a custom exhaust made for the vband on my turbo so I don't have an o2 housing.
