I would make another pull when the car is fully warmed up also, but yes I would try adding some fuel in that area, as according to the AEM, you're getting up around 11.7:1

As a test, what happens if you yank the timing sliders from 4500-6500 down to -16°? If you STILL see no change in knock retard, then there's a problem. If you do see a change, then at least you know it's a tuning issue and you can simply pull timing until it stops. *Why* you have to pull so much may be a mystery, but at least you'll be moving forward.
Geeze man, that is really crummy timing. The ~2g timing worked well in my 1g with 8.5s up till probably 24psi. Did you try just dumping that in (maybe smoothed out a bit)? Im running this if you want to try:
1.5k -1 .......... 2k -2 ............ 2.5k -1 ............. 3, 3.5k -5 .............. 4, 4.5, 5k -8 ................ 5.5k-10............... 6k-11........... 6.5k -6 ........... 7k-4 ............ 7.5, 8k-3
I have the same problem with my UEGO. I cant log the gauge face numbers with any real trust; however, a/f estimate seems to be right on in my car, I occasionally just gauge watch during pulls to check correlation.
Tires got a lil loose, but moving back up in the world of timing.
The WB logging issue is a bit perplexing, though. Without accurate WB data, it's really hard to gauge "good" timing values. If you're really running 11:1 on pump gas, for example, I would fully expect to pull a lot of timing.
The WB logging is what kills me about the whole thing. I can assure folks all day that it drops off the gauge (11.1 is the last number seen IIRC) before Link sees it do so, but not everyone is inclined to trust my eyes.
BoostEst is about 2lb high at 6000rpm and I had to let off for traffic. Timing topped out in the 9* range. Feels pretty good, to be honest, but there's still a touch of knock.
Kris, maybe you posted this before, but how are you running 1000cc injectors at 11:1 with no fuel slider movement?
AEM wideband tomfoolery, sir.

MAF-T is v1.1 and settings are for 450s.

That, I can manage.

The global with these PTEs has always been a fun one. Trims look good, so I think you're right that it shouldn't be too big a deal...though I'm rarely certain about the odd things like this.

This is what gets me, too. Smells rich, some soot on the bumper, WB gauge reads rich...
I'll get the buffer tomm, and wire it in when it arrives.

Do you mean because he's running 37psi fuel pressure? If so, the V3 application lets you specify that in the AFRatioEst properties. No need to adjust the injector size. Just enter 1000 cc/min and 37psi if that's what you're running.
