JB4 Default Boost per gear w/AWD

CheesecakeInjection · 06-12-2019, 10:27 PM

If I have an AWD 335i, can i use JB4 raise my boost per gear (above its default settings) as my traction can accommodate? And Will map5 be able to make this adjustment itself?

Did a google search to no avail...
thanks!!

JB4 has boost limits per gear that can be manually set each for 1, 2, and 3rd.
Map 5 will still adapt tuning to the best for your engine, not traction.
There is no ability for JB4 to adapt your boost limits based on a history of available traction.
With AWD, there's no reason to set a boost limit in 3rd and probably no reason for 2nd either. It's more of a RWD thing.
