Hi All,

I have a 2017 M240ix 8ZF. JB4+DP+intake. Love the JB4; massive gains. That being said I have noticed that at WOT, there is a noticeable delay between shifts. When the JB4 is uninstalled (or map 0), this thing bangs through gears.

Has anyone else experienced this?

nope,

same car, also JB4 ( no DP ) running Map 1 , but no hesitation at all between shifts !!, wich map you are running 1 or 2

Occurs with All Maps 1,2,3 & 5

With any map it feels like it takes .4 seconds to shift. It almost feels like I'm driving standard (like neutral between gears).

I notice when I'm 3/4 throttle its instantaneous, and once again bangs through the gears.

How do the logs look?

The dme is going to try to protect the transmission by cutting power on shifts.

I haven't. What would I be looking for specifically?

[kriszty]

try map 0 , then maybe the jb4 is causing this

Saw your logs on n54 tech. Your boost is all over the place with throttle closures too. I think you need ewg wires to control your boost better but confirm this with the experts over there
