Default Weird knock / loss of power event (UTI logs)

This happened this morning on my way into the office. 6th gear, cruising along. I shift to 5th to pass someone and go WOT and this occurs:

I know I'm still running rich, its slow going when I remove fuel...very paranoid. Anyhow, it seems that my AFRs jumped from 10.5 to 12.7 while fuel, timing, and boost stayed within the map's specs. What's the deal?

Car literally lurched forward, it didn't feel like a normal knock event where timing is pulled. This felt like a complete fuel cut off, but only for a fraction of a second.

You have a rapid decrease in IDC from 92% to 76% in one line. The UTEC is scaling back as it gets away from the 90 column into the 80s, 70s. Check your fueling in the 70 and 80 column around 5krpm and see if it differs from the 90 column drasticly. Oh and what fuel pump do you have?

Could the italics above be the issue? AFRs seemed to rise to 12 before the load dropped into the 80s....

You are way, WAAAAAAAAAAAAAAAAAAYYYY lean

mid 12's under full boost on pump gas is a recipe for a new motor. You need to be adding fuel in there to get the a/f back into the mid/low 11s

Did you make those changes??? If so, dude, load the off the shelf maps back on and wait for me to help you before you blow the thing up.

mid 12's under full boost on pump gas is a recipe for a new motor. You need to be adding fuel in there to get the a/f back into the mid/low 11s

Did you make those changes??? If so, dude, load the off the shelf maps back on and wait for me to help you before you blow the thing up.
I didn't modify the fuel to put it there. If you look at the rest of the pull, the AFRs are normal (~10.5:1). The PROBLEM is that for somre reason, it jumped to 12.5 for those 4 lines (maybe 1/4 of a second). That's what I need answered.

I'm using the UTI logger now, it pulls data like 10 times a second...so what looks like a normal UTEC log at like 2 lines a second is actually taking 10 lines a second. The rise to 12.5 maybe took half a second at best. It was enough to scare the crap outta me though.

CN: I didn't make it run lean. All of my AF lines before are ~10.5:1. Included my current map as evidence.

Maybe you were seeing fuel starvation due to some unknown reason? Wouldn’t this cause the IDC to drop at the point where the lean AFR was observed? Also, 90% IDC is pretty high don’t you think? Especially when combined with the stock pump. So I guess the problem here is not so much the knock event (as it's not surprising) but instead the drop in IDC and lean condition experianced (which in turn caused the knock event)....

That could be the case. I'm being forced to revert back to the Stock Stage 2 map from TurboXS (which is pig rich) a bunch lately after my tunes fail.

The car running rich seems to be a terminal condition. Anytime I run anything leaner than about 10.6, it knocks horribly.

You have no room to be any richer. Look at the IDC's, they are well into the 90's pretty early. Tuning more fuel won't do anything, they are already basically at static spray. Considering that your car is holding low 10's AFRs all the way, I really can't imagine being *richer* than this (it would take a fuel system upgrade anyways). Granted, with extra boost in 5th and 6th gears, you will "gain" back some AFR towards lean, while injectors simply spray 100%...

Have you investigated false knock? 10.6:1 seems excessive for being neccesary to prevent knock. Being too rich can also contribute to knock events, so I'd probably look to more conversative timing as a way to deal with knock before adding even more fuel.

GL

EDIT: Anyone else notice the odd boost action in the bold range?

I'd say there was a problem reading a sensor, an electrical blip or whatnot. Some unusual electrical load might have caused it but it does seem like a fluke incident. The UTEC definitely scaled back the injectors but as to why I don't think we will ever know.

Change the cl to ol transition time to 0.5 sec. or less and the ol to cl to 2 sec. in the parameters menu.

I fail to see how that would help him. He is wide open the entire time...no crossover is happening here.

I did shift gears, but it was well over the default 2 seconds it takes for the crossover to occur (at least I think its 2 seconds)

Good idea nonetheless. I'm going to chalk this weirdness up to a grounding issue. Hell, why not?
