The ignition has improved a lot?
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):

Recent (only +5c):

B48 engine should be 530 oil or 540 oil?

I let BMW handle that, and I would refer to your service manual, but I'm pretty sure its 5W-30.

why your 98 RON gas quality is so bad?

I'm also in China, here is my log which is logged in the summer (about 30 C degrees above)

会拖档的,在1000转左右。用换挡拨片降档或者切sport模式解决
ACN91的log看起来比普通91好一些,但是动力会差些
北京中石化的油品这么差的么。。。。

So, map 91 = 95 euro, map 93 = 98 euro.

So you'd typically use stage 1 93. The maps seem to be tuned quite aggressively in terms of timing assuming high quality fuel, while many seem to experience that their local gas station does not provide the required quality.

So for instance myself (and many others) have to run the 91 (95) map despite using 98 octane gas.

You should also post your logs here and/or send them to PTF to verify that your car is working properly with the tune.

I also run oct91 with ron98 gas. As weather gets cooler now, I'm considering of stage 2 for more power. Is stage 2 any big difference from stage 1?
The log seems better than in summer.

Hello I read your log
http://www.bootmod3.net/log?id=5d9b2951c090c61ab1d89b59

Is that stage 1? Why does it look so different from mine mainly in high rpm where your boost remain high at around 18 psi while mine is at 15 psi.

I'm also with Oct stage 1 91 map.
http://www.bootmod3.net/log?id=5dd8bc51c090c60ec88333f2

Maybe you had downpipe so you can keep high pressure through the high rpm?
