Need help analyzing my vag-com log

B6/7 S4/RS4
#1

I did a log of 003, 020, 021 per some advice from this forum to troubleshoot my car.

Can someone look at this log and tell me if anything is not as it should be?

It’s a link to a public google doc.

Car has JHM tune and piggies/exhaust. MAF reading peaks out at 267.8, and timing pull is generally between 6-8.3 across all cylinders. Is this within spec, normal?

This is why I’m troubleshooting if you’re curious:

Based on that log, everything looks pretty good. Your RPM/sec are pretty strong, MAF seems in check, and timing is good (pretty in par for piggies). Kinda not what you wanted to hear, but it does seem it’s a strong running car under WOT.

For bad gas mileage, I’d be leaning towards an issue during cruise and part throttle. If it was bad though, I would think you’d have a cel or some underlying codes.

Go to:
Select
Engine
Fault codes

(quick way to see any engine codes without doing a full scan)
Sometimes there’s some codes that are there but not enough to throw CEL.

Another thing to check is to just take a snapshot of block 032 after 15min of driving or so. Just grab those numbers a few times while at idle, and it’s important that you’ve been driving for a while and that you keep the car on when you grab the codes. That’s your long term fuel trims for both banks.

what fuel and how was the weather?

try logging 003 with the car idling (may be in that same log)

#5

Weather was about 50 degrees, on 91 octane.

I’ll try grabbing fuel trim with the car on, last time I tried the car was off and it read:
Adaptation (Idle) Bank 1 Sensor 1: 1.1
Adaptation (Partial) Bank 1 Sensor 1: 3.9
Adaptation (Idle) Bank 2 Sensor 1: 1.5
Adaptation (Partial) Bank 2 Sensor 1: 2.5

I’ll log 003 at idle and partial throttle next
