Can someone please take a look at some logs?

Having trouble figuring out an issue with my car... Im getting no CEL, but there is a "fuel pump plausibility" code with no light... it come sup stock and stage 1+ cobb tune. Can anyone check out these logs to see if its something obvious?

Wont let me attach them , I can email or dropbox them

I'm confused - what's the issue?

The log you posted has very active boost oscillations so either you let off the gas a bit, or the throttle plate was trimming. Without seeing those channels logged it's just speculation as to why.

2AAF on it's own is acceptable and doesn't actively interfere with anything. Fuel pressure looks stable to me on the low and high pressure sides. This is a pump gas scalar anyways so the strain isn't quite as bad on the HPFP.

The car feels odd in boost at higher rpm..

I dont think I was letting off the throttle.. What channels should i do in the log? I have never done this before.



Im starting to think its the cobb stage1+ otc tune. I never ran it before, my old 135I went straight to their highest tune FBO.

Copy my logging channels, though if it's pump gas you don't need to follow some of the fuel channels as closely. But make sure you log load, boost, and throttle channels so we can see if there is overshoot induced trimming, or if you just accidentally let off the throttle a touch.
