2 logs need to lower abit at 5500 i think to around 15 PSI.

logs have been sent to george to fine tune this a bit more.

I'm going to try this tomorrow,
1500 12
2000 13
2500 14
3000 15
3500 16
4000 18
4500 18
5000 17
5500 15
6000 15
6500 14
7000 13

or whatever george sends me to fix lol

Looks really good. Still stock downpipe? Right? What fuel are you using? The IS12 doesn't like as much boost from 4,500 up. Especially on the stock pipe. You can probably make your 3,500 18 and then lower the 4,500 to 17.5 see if you get any more advance in ign1. If you gain 2 or more degrees, it's worth it

I have a better example here. It is happening consistently for me.

The lean spikes toward the bottom of the pull are what I'm referring to.

Random spikes are fine. They are glitches in the logging. The Ecu can't react, change and then read that quickly. The only time you need to worry about a lean condition is if you see it go 15 or higher for more than a few hundred rpms which would be like 4+ cells in a row. When you see it spike up, but it's good right before and right after, it's ok

Here's an interesting log to me. Something weird is happening? I'll let it speak for itself..

What twindad says has been right for him, and I would probably agree with him for most of what you've shown except in your first log in 2nd gear at 4800-4950rpm where the ignition suddenly drops and your trims shoot up exactly in line with the AFR jump. To me that says that something is up as if I understand it correctly those values are measured independently. Do you have the AFR wire tapped or are you using the extrapolated values? If you don't have the AFR wire tapped considering how consistently this is happening to you I would connect that so you have more information related to the problem.

It depends if you're tuned or not. On a stock tune mostly anything above 15 is considered lean, and you will rarely see values below mid 13's. If you are tuned then at least APR tends to run very rich, hovering around high 11's, and because of this AFR is not really a concern.

My AFR wire is tapped, but I'm going to check the circuit with a meter to verify it. Is there any way to verify it in the software?
