Default b48 125i jb4 issues - 01-19-2022, 08:59 AM

Hello guys

I have a f20 125i with b48b20b engine. I installed jb4 and i have some problems;

I used to own turbocharged hondas and we used to kept our afr under boost like 11.5 12. But in this car in the wot runs i always see values close to 14.7 till redline. I know this engine is a direct injected engine and designed to run a little lean but i am not feeling comfortable what do you think ?

My second problem, in the map2 when making wot runs, when i pushed the accelerator, it feels like there is a bump in the acceleration, it is not smooth.

I took some datalogs ( map 0 map1 and map2 ), would you please have a look to them ?
