Poor communications....you might need to slow down the canbus rate with the FUD bits. Nothing else in the OBDII port and no other accessories correct? Connect kit powered properly?

Ok, I will slow down the can bus rate; no, i have nothing in the OBDII, just the JB4, Connect kit well powered (Good ground and 12v connection).
The can bus rate is on the menu from the Ios App?
How can I slow down the bus rate by the IOS App or the pc ? BMW F25 does not have the Dash and control wheel active.

Check your JB4 mobile install guide...it should not be 12 volts.

Looks pretty normal, a little DB tuning may help hold a bit more boost up top.

Map 2 and map 5 look pretty similar.

Why is so similar, map2 = 12 psi and map5 = 15 psi right ?
It’s something wrong in the JB4 ?

Similar curve, with a slight difference in target boost. Map 2 will likely be more consistent with slightly higher boost target based on current map 5 learning. Map 2 was targeting 14psi at tip in and then tapering.
