I JUST need the number of turns, not how to adjust the biss
I dont have ecm link
Thanks

Basically 1 1/2 - 2 turns out as just a starting point.

If you dont have ecmlink then its best guess really, it might be somewhere around 3/4 turn out or 1 3/4 depends how your cars acting, i would adjust it so your revs are decent when warmed up and leave it, ive done it this way and its been fine for years and i rebuilt my TB many many years ago

It can also depend on if your throttle stop has ever been moved or not if running a factory throttle body or aftermarket. I usually had mine around 2 and 1/2 turns to 3 turns out on all my throttle bodies. Your best bet is to get it a good idle when fully warmed up and leave it like previously mentioned since you can't log isc position. I would also make sure the oring on your biss screw is in good shape.
