Oh okay.

Those instructions for Autotune I found were for Hondata Romeditor. Sounds like a more efficient way of using autotune, because it takes averages over multiple load conditions as opposed to tuning it in real time (and resulting in jagged fuel curves).

Know what I mean?

Tell me please if this method for autotune is correct or not:

1. Load calibration.
2. Set as base.
3. Drive around under different loads to get a good average lambda correction suggestion.
4. Ctrl+T (which then autotunes the lambda suggestions).
5. Set as base (so that the newly autotuned map is ...

Well, I tried driving around holding ctrl+T for a little bit...didn't seem to do much.

And seriously, how am I expected to drive around while holding down ctrl+T...

Never mind. I found it when I searched google (but not when I searched the forum?!).

Can someone please explain to me how to use autotune?

That's exactly what I meant, no longer need the weaker narrow band for closed loop.

Correct me if I'm wrong, but the entire point of running the car's closed loop off the wideband is so that the stock O2 is no longer needed, correct?

Of COURSE I asked too soon...

Didn't have a calibration loaded...how embarrassing...

I've recently removed the stock O2 and installed an NTK wideband.

I followed these instruction: https://www.hondata.com/techplxwiring.html

When I open s300 and go to parameters/closed loop it will not allow me to select or alter anything whatsoever.
The ELD reading shows 4.5v (as it should) seeing ...

A B20 does not have the correct location to mount the knock sensor so that could be part of the issue. Also aftermarket pistons can make a lot more noise than stock and be giving false knock readings. You really need a way of listening for knock with headphones to be able to ell if what you are ...

It's a P72.

I have a very short datalog to show, but I'm not sure how to upload it to the forum.

Didn't work out very well, I went back to the ls vtec map provided with the s300 v3 software.

Thanks for the map! I'm going to try it out on my new b20v as well; stay tuned for feedback!

To be more accurate, I'm running the latest version of s300 v3 (2.5) and the base map is the LS VTEC ITB's 440inj map.
