228i BM3 Stage1
Hi all. I know there are very few dyno charts for N20 so I would like to contribute mine.
I have done a stock test and a BM3 stage 1 OTS 91 Octane test to see actual gains. The relevant mods on the car are are: - Mishimoto intercooler - Masata Aluminium turbo to intercooler pipe - Masata Aluminium charge pipe - GFB DV+ - K&N drop in filter Both tests were done on RON95 gas ( 91 octane ). Problem is, when I have done some pulls, I get knock detected and timing looks a bit weird to me ( compared to other logs I've seen from other cars ). I attached screenshots of the knock events. Full logs: http://www.bootmod3.net/log?id=5ded59eeae729b43107e09d1 http://www.bootmod3.net/log?id=5deeba4bc090c64ca2e5d683 Any feedback would be appreciated, as the only answer I got from BM3 support was "Overall looks very clean, nice timing curve.", which does not clarifies my knock issues. I think the problem is bad gas in my country, but I have very little experience reading logs, so please pitch in.

I suggest you send the logs to PTF direct

Done a few more logs last night to check if I could use this tune on the track with better gas.
The map I used is ACN91, should target lower octane gas and I filled with RON100 gas. This was my third fill-up with RON100 so leftovers from the previous RON95 should be minimal to non-existing. RON100 should be about 93 Octane. I did 5 pulls, got Knock events on 3 out of 5. This are the logs with knock: http://www.bootmod3.net/log?id=5e617163d10b434580197285 http://www.bootmod3.net/log?id=5e61704ad10b434580197258 http://www.bootmod3.net/log?id=5e61702dd10b434580197257 Any feedback would be appreciated.

My support ticket was updated with the following answer:

I also don't understand Halim's conclusion, when I look at the logs I see timing being retarded on different cylinders, on last 3 logs there is a different cylinder every time ( 2, 4 then 3 ). But maybe I'm reading it wrong, an wiki on how to interpret logs would go a long way.
