2020 BMW 330i xDrive (G20) - JB4 on map 6

2020 G20 330iX running a JB4 on a custom map 6 and a splash of E85 (roughly between E20-25; this run was done with a lower ethanol content compared to usual runs).

Dragy numbers:

0-60mph - 4.88s
0-100kmph - 5.10s
0-100mph - 11.24s
100-200kmph - 13.11s
0-200kmph - 18.21s

This was not my fastest run. I have done sub-13s quarter miles (three runs at 12.95, 12.97 and 12.99s at 107-107.2MPH) with the same set up but no videos (only dragy timeslips) unfortunately since those were spur-of-the-moment runs.

Nice video man, question, how much gallon of E85 you were putting on in a full tank?

Hi brother, are you able to show me the value/numbers for the Map6? I never used the Map 6 functions. Thank you!

Hey man, I have some questions about the JB4

1. How’s the reliability? Any issues with the car since installing it?
2. What do you mean my “custom map?” Can you make custom tuning maps for JB4? Is it for all of the maps?
3. I looked on BMS and the EWG cable seems to only be for the N20/B58/ and another engine (but it’s not the B46/B48). Does the B58 cable work on the B46/B48 as well?
4. Is the JB4 consistent? Also why do you lower boost in the summers? Does that help protect the car?

Thanks and have a good day
