That's kind of the way it's done in other masks ... but differant code. Like $42 uses Open Loop RPM Threashold so there is a Idle on and Idle off RPM, has to go above Idle off to enter CL and below Idle on for OL. There are other settings for open loop idle as well like TPS% and MPH. But this mask was designed to have some cals run OL idle, like all BB engines.
