I went to a shop yesterday and the guy saw that my fuel pressure regulator adjustment was loose, but to figure that out, he spun it, so maybe he changed my fuel pressure, which I could definitely see causing knock

You need to add some boost enrichment, as you are lean as the boost rises.

Your tracking is not enabling (correction factor does not move)

Not sure about your boost control, the solenoid is activating, but your boost is falling off. Recheck your wiring and plumbing.

It will probably not hold 16 psi to redline, but it should hold better than it is.

11.7 may be a little lean for pump gas, but with stock injectors, you won't be able to push it much richer at 16 psi. Are you running the stock fuel pump?

Any help bob?

Dashpot. Idle at 1K (850 on datalogger) helps too.

How do I enable the tracking mode? I moved the boost past 14 just to get it to spike a little higher before it drops off, but you think it should still hold higher than it does eh...hmm, wonder why it's not. The solenoid is on right, i'm 99% sure of that, and there was essentially no wiring that needed to be done, just plug everything in.

I have a hotwired walboro, so I should be getting plenty of flow for my current turbo setup.

Maybe the afr tracking is also responsible for my random days of knock (and maybe not) lets get that on and see what it does. How do I enable it?

Thanks Bob

What are the settings in your AFR tracking page?

I think I found my problem for why it wasn't enabled...in two places.

Originally my settings were:

Min TPS: 4.9
Min RPM: 2016
Min Load: 166.4
Lean Lim: 10%
Rich Lim: 10%
Gain: 4
AFR 2000: 11.9
AFR 3000: 11.6
AFR 4000: 11.7
AFR 5000: 11.9
AFR 6000: 11.9
AFR 7000: 11.9
AFR 8000: 12.1
Aux %: 0.0

My maximum TPS is 4.86, so I turned that down just now to 4.74. Also, I put my Min Load to 143. That should enable it. My wideband tends to read about .1 to .2 points richer than my maft pro, so 11.7 shoes up on the maft as 11.8 or 11.9 (I soldered the connections, but at least it's rich as opposed to lean). Let me know if anything else jumps out at you

Thanks Bob

you can set the TPS enable lower than that, but yes, that should enable it.

Yes the dashpot works. I am not running 02s, I am running with tracking. I do not have a log but can get one. I was hoping there was something I could change to compensate for this.
