Ah ok, figured that's what you were talking about but just never heard it called that. I just blocked mine off with a plate (at brad's suggestion mind you), and the throttle its cracked maybe 2% and re calibrated. It'll idle a little rough at maybe 800 rpm cold and fine warm at about 1100. If its easy enough to setup on the megasquirt then why not give it a try. You still have it hanging off the manifold don't you?
