Dear,

I have a bmw 530E 2019 and bought MG Flasher. Now i just dont know how it runs… Im not that professional and hope if someone can see if its good or not. Let me know please!!

Stage 1 normal Ron95

i always tank RON 98 at good quality gas stations. My sparkplugs are new and oil changed 1000km ago. So everything should be good.

For now i have a map on RON95 Because a friend om mine told me that it just safer on RON95.

Got 2 links for the logs.

Can you trim the logs and just post a 3-4th gear pull or just a 4th gear pull?

Start the logs from 2.5k rpm to just under redline to capture the most data.

In my experience logging my custom tunes, Cylinder 4 seems to be pulling more timing than the other 3 on one of your logs, anything to -3 is usually ok, if higher than that on all cylinders it would be down to low fuel quality and if its just higher on 1 cylinder then you would need to look at sparkplug/coilpack issues maybe . My experience is on the B58 engine though so maybe the B48 behaves differently . Maybe check all sparkplug gaps are even and no damage to any of the coilpacks

you should log again on the 98ron map with 98 ron fuel to compare the logs.

You want to see 0 for knock detection during the pull and timing corrections less than -3 in my experience

I have a 2018 530e and have a stg 2 tune from MG Flasher. We have poor quality fuel so I am running a lower quality fuel map. It's a 91ACN map. It's just like the 95RON maps but dialed back a bit.

I agree you should re-log in 3rd from 2-2.5k ease into full throttle and let the car run to redline in 4th. Your timing corrections look ok ish, but ideally you want none. I think the 98RON map might be a bit aggressive if you are already seeing timing corrections with 98RON fuel on a 95RON map.

Here is a recent log from my car. If anyone else wants to chime in let me know.

Hope this helps.
