BMS JB4 R specific thread

Langer said:

I've done a search and couldn't seem to find the answer.
How the heck does the data cable fit inside the plastic JB4 enclosure? Noob here with a new 2018 golf r, coming from a 2007 gti (unitronic 2+). I didn't want to flash tune the r since I last my warranty early due to TD1 flag by VW.

Is it safe to use map 1 on jb4 and not plug in the OBD connector or tap afr wire?

Don't you have to at least connect the obd cable?

Thanks Diggs. I found myself a cable and decided to tap the afr wire and set to map2.
Here is my log. What do you think?

Any map 6 suggestions? My only mod is an ebay intercooler running 94 Octane

Is the goal to have as much boost as possible while keeping timing adaptation <2?

And also, why taper down the boost at the very end?
