Next time, do a full throttle run on a single gear from 2500rpm until redline. And several of them using the same part of the road. Partial throttle logs don't tell much as the only diagnostic device.

I might have been unclear. In order for any of us to give you proper tips we need a rather specific log:

Car already moving, on 3rd gear, rpms 2000-2500 -> open throttle fully (pedal all the way down, if you have AT, don't activate kickdown) and go from ~2000rpm on 3rd until you need to change to 4th at full throttle and give it few more seconds of full throttle on 4th gear.

Be sure that you have safe surroundings, level and dry road with no traffic. For comparable data, use the same stretch of road for all of your logs if at all possible.

Remember to fully deactivate ESP by holding down the DTC button for 5+ seconds so that it will not interfere and skew the log.

Check one of my logs as a reference: Datazap

Still not a perfect run. As the previous poster stated: Go to around 2500rpm in 3rd gear and keep the throttle steady, then smoothly increase throttle (1-2 seconds from 2500rpm to your pedal is all the way down) to full throttle without triggering kickdown, then if you have space, shift to 4th and go as far as you can there as well.

Timing seems low, but perhaps that's how it intentionally is on the ACN map? I can't see any knock.

Why are you running 91 ACN if you have 98 octane fuel? I assume this is a 320i?

I don't think you need to worry about knock events at low rpm and with low throttle. What you want to avoid is knock events during acceleration.

Timing is a bit low but seems reasonably stable during WOT. Again I'm no expert. You should submit your log to PTF.

It's been sent but they say it's safe and healthy but I think the ignition is low and the PTF tells me that the oil here is of poor quality

Then they're probably right. That the ignition is low isn't a problem in itself as long as it's stable, it's just your car correcting for the fuel quality. Have you tried logging stock to compare?

Yes. But also lower power, so.. You won't get that high timing on a tune. Depends on ambient temps too.

For comparison here's a couple of mine (also B48) on 91 stage 2 beta tune, running 98 octane fuel.

June (high ambient temperature):
