Actually, you can drive around half decently.
It's not hard to forget that last step of plugging the connector onto the
AFM of course, which is how I found out.
They run quite well, though unevenly, especially with a lot of pedal
applied.
I doubt that it hurts anything. The ECU is just temporarily confused about
how long to hold open the injectors. I imagine it overcorrects a bit.
Also...........WOT is a mode that bypasses some inputs I believe.  It'll run
that way fairly well.
