If I set it to 1000rpm with scanner controls it all works normally but left to its own devices it tries to make it idle at 0 rpm even though thats not whats in the tables.
I think I remember someone having issue with a Max Idle RPM table set to 0 but that was in manual OS I think, this is a 4L80e segment swap, with the PN Only switch set to indicate when in/out of gear.
Pull it into gear and pretty sure desired idle goes to normal because it will usually calm down
