If the BCV has a plug, it will be much easier. Here is how:

Unplug the BCV. ignition on, one of the wire will be 12v and the other near nothing. The pulse wire will be the "0v" one. Do not use the DR1 until yuou have sorted thje wiring out first.

What is the standard boost?

But the BCV is unplugged, you should run wastegate pressure. Let me know what the boost is when you unplug the BCV.
