320i b48 with bm3 logs

haibebei · 08-09-2019, 06:38 AM

Hey guys,

I just flashed my car to bm3 stage 1 octane 91
My car is 2018 320 b48 stock
The logs:

http://www.bootmod3.net/log?id=5d4d4fc9ae729b1bf7ba2b05

http://www.bootmod3.net/log?id=5d4d50bcae729b1bf7ba2b08

WOT in 3rd gear, any thoughts?

I run with RON98 fuel in China.

The car felt much stronger than before. The butt felt like it's a 330

Just wondering whether it's safe to run or not

took 3 more logs

they looked good except for the first one there is 2 knock...
and the throttle angle seem always not 100 which is a bit strange, should i worry about that?

Looks like it's running a little bit lean, which could explain your throttle closures. That said, I'm much more familiar with the 328i than the 320i, and haven't looked at many other 320i logs. However, I doubt an average AFR of ~13 is a good thing. I would reach out to PTF about it...

I already sent it to PFT and see what they'll say.
I think 320 b48 run lean is very typical thing?

Doesn't look that lean to me. It goes below 13 when approaching max rpm. AFR looks about right.

Found a stock 20i map0 log which is running lean so bm3 actually tunes better and made it around 12 near redline

Perhaps the B46 runs leaner than the N20. I wouldn't be comfortable with anything consistently close to 13 for my N20.

stock B4x/B5x runs low/mid 14's, barely dipping into high 13's at high rpms.
