New 3rd gear pull @ 20psi

[VisionPaintball]

I was having some issues with knock before even after pulling timing, so I wanted try some Sunoco Cam2 gas (100oct). Seems to have gotten rid of most of the knock.
Can I just run this gas from now on?
I might look at a meth injection kit next as well as a larger fmic.
Anything jump out from the log?

Thanks, I am trying to learn as much as I can about link.

Looking at your WOT section of the log, compare your AFRatioEst to your wideband. It looks like you're airflow isn't dialed as well as it needs to be. The ECU is trying to hit AFRs in the 9s and the wideband is reading in the 11s.

your timing is awfully low for such a low boost pressure. I would be more near 18-20 degress everywhere, except when you peak at 21 psi for a breaf second at 4k.

I agre you need to dial in link and your WB to be accurate before anything.

Is it my airflow or my global settings which are off? If I lower my global setting wont that richen the afr's and get them more inline with the DA table?

You can't think in those kind of terms. The best solution is to get everything dialed in appropriately and tune from there, instead of making changes somewhere else to cancel out a mistake elsewhere. For FIC 850s, your global fuel looks just fine. What you'll want to do it make adjustments to airflow. This can be done pretty easy with some time/patience. There's a very useful tool called MAFCompAdjust. I would recommend watching the following videos over at ECMLink's website to give you a good idea on how to do this. Also, the Wiki has some great information on getting airflow dialed in properly.

From ECMLink's website:
WOT:

"Then I do a few pulls and look at BoostEst around 5500-6000 RPM to make sure it matches with what the gauge was reading. Some deviation is expected, especially as revs increase. But more than a psi or two and I feel like I want to tweak the airflow sliders some more. You can calculate the amount to move the sliders if you understand absolute pressure and how to calculate scale factors. Otherwise, just lower the MAFComp sliders if BoostEst is above measured boost or raise MAFComp is BoostEst is lower than measured boost.

Once that's done, I'm usually pretty happy with the setup and can start tuning."
