2019 C43 JB4 performance
A few questions regarding installation; am I correct in understanding that the purple wire patch AND the green wire patch are not used? Also would it be easier to install the bluetooth connector prior to the rest of it?
Thanks
The BCM is needed in addition to the JB4 on my 2019 to give me the same power that a stand alone JB4 gave me on my 2018? So really a JB4 on my 2019 without the BCM isn't doing much for me then?

For 2019+ models the JB4 alone adds a lot more power vs. factory and most 2019+ customers still only add the JB4.
But to get up to 2018 max tuned levels (those running E85 mixtures, 11s 1/4 miles, etc) then the BCM is also required.

You have a 2020c43? How did the car responded to the jb4 and bcm? I am local in Socal and though I am not around BMS facility, I can get there within an hour. I have always considered their tuning module but with the lack of supporting data as to how the facelifted responds to it. Lastly, did you install the piece by yourself?

Do you have dyno graphs with and without the BCM ?
Before buying this over my jb4, it might be interesting to know what's the gain with the bcm on facelift model.
