Bac issues

Trying to figure out issues with my t2 swapped s5 vert. It's running a Pfc and bonzai adapter harness. Bas is currently unhooked, and it's idling so so. I'd like to get it back hooked up and running proper. When connected it revs up to 3k+ and surges. Have tried resetting the pfc and learning the idle, but no such luck. Anybody have any idea of what to look for next? (I'm running around in circles on the forums trying to search for things, hopefully somebody knows something.)

If you have the JDM BAC it will not have the adjustment screw, regardless of which one you have you need to readjust all your previous throttle body settings. Being able to adjust the BAC makes things easier

You will also need to adjust the fuel corrections for the idle area of the map.

So the BAC has been adjusted when Unplugged to the point of the car idling relatively fine, but when plugged in, the BAC opens 100% and the engine revs to the moon. Just trying to figure out why the BAC is going full open and not trying to modulate air at all.

Take is off and clean it. Adjust it when it is plugged in not when it is unplugged. When it is unplugged it is just an unregulated vacuum leak
