Howdy. With my supercharged LN3 setup, since I am using the LN3'* wiring harness and ECM, my BCA (the boost or bypass control solenoid, I can't seem to ever remember which it is), goes unused. I still have it connected as it normally would be, minus the electrical connections.

Can I remove it? If I do, would I use caps or a "jumper" hose in place of it? Thank you.

Just cap it off...but...what do you do if your engine needs to dump boost? I guess it doesn't matter since the ECM has no idea there is a supercharger there anyway...

Thank you. I'll pick up some vacuum caps.

Well, if my engine needs to dump boost, I would have always wished it could have

Don't cap the bottom port of the BCA (cylinder). You can just remove the BCS (electrical little box) all together.
