Hi, I installed my JB4 with v16 firmware a few months ago but never made it to do a few 0-100 km/h (LAUNCH CONTROL) runs till last weekend. All runs were done on the same road from a same starting point. And I have four 19'' Rays G025 forged rims with Michelin PS4S tires, a BMC air filter and a full tank of 98RON fuel.

statistics:
1. Map 0 (stock map)- LC - 7.4s
2. Map 2 (around 4psi over stock) - LC - 6.73s
3. Map 3 (around 6psi over stock) - LC - 6.45s

I have to say I'm quite surprised and excited with these numbers for a 184HP version engine.

PS: I also have a B48B20B engine and BMW etk shows that the part number of my engine is totally the same as the one on 330i. It seems like that in early 2019 all 320i models were also manufactured with B48B20B engines and in later 2019, they were replaced with B48B20A or B48B20D engines.
