Help with ID2000's

[a1320honda]

Having issues with gettin my teg to idle consistently with ID2000's on E85. On day it will idle just fine at 15.5 afr, then all the sudden it will just start idling up and down. I read your supposed to use the same offset settings as the ID1000's. Anyone have any insight? Fuel pressure with the line off is 43psi.

What are you voltage offsets? Idle is difficult to use for tuning as the intake temperatures change, so driving at very light throttle usually works better.
