Help with knock issue

[plasmid]

Whats your fueling look like? Possible something happened to that and its getting lean?

So I've had a look at the log again. I've attached a photo but it's not ideal or helpful.
Blue line is rpm (4400), speed around 56mph.

Right where I think my problem is, AFR1 0.84, AFR2 1.17, STFT1 1.03 and STFT2 1.25.....

There is a small amount of knock (0.25) just before or at it.

I don't know if those numbers are the cause or the result of a problem though..

So is the STFT2 trying to add fuel?
O2 sensor or fuel pump?

I've sent logs off to Lund and see if they can see anything. But I think they are pretty busy at the moment. I'm also booked into a mechanic next week.

So for those playing at home.

Changing the oil back to 5w-40 has not fixed my problem...

Ok so I decided to re-log. I didn't really want to as I am too scared the engine is gonna blow.

Link below to datazap.

My issue is captured at 4000rpm. It's the only peak that goes that high.
I have some idle, rpm holds and then a relatively slow build up in third up to 4000rpm.

Good luck!
Have you had a chance to check your exhaust for anything?

I am trying to remember how all those numbers work. It seems bank 2 is trying to add fuel and not getting enough. I'm sure Lund could tell you in 2 seconds when they look at it though.

I hope they can pinpoint it!

I had a look - but I’m not an expert by any means. There’s some really smart guys here that hopefully point to something.
I don’t see anything obvious. You said at 167 seconds - It looks like it’s happening at 4900 RPMs. BAP and voltage are fine. Can see fuel pump voltage goes from 49 back to 29 (double it for duty cycle) AFR looks good. Right at 167 seconds knock goes from -4.12 to 0 but I don’t see where it hit + anywhere except far later at 283 seconds where it’s +4.92. (- is good + is bad) The torque sources that show up 16 and 5 and 6 are deceleration, tip in and tip out. So just so I’m clear. You’re slowly accelerating and all of a sudden the car just stops accelerating and bogs down?
