I’ll let you both know when I’m gonna be that way. Cape Canaveral will on the list as well, maybe the keys? No time soon, but sometime in the next year.
May be something Dan can check out then.

After reading these last few pages, I'm tempted to box this MPVI2 back up and post it in the classifieds.

Well my changes aren't seeming to work. There must be another table I'm missing that controls fueling below 1200rpm. I can't see it needing the same fuel at 1,200 rpm no throttle as it does at nearly 6,000 and WOT.

why is your engine running at 400 rpm?
check for exhaust leaks

I don't believe there's any major leak, certainly don't hear or smell one but I suppose a looksie wouldn't hurt. The dip below 800s is from startup and when I engage the clutch and the rpm dips down, this is dramatized by the lean condition making it want to stall and jerk violently. I'm fairly certain anything under 800 registers as 400. Let me see how many counts those cells hit tho.

you have cleared the fuel trims since disabling them right?

Yep LTFT has been disabled basically forever, and I recleared them this morning thinking it was an issue but I saw no change. Would a vacuum leak cause this? I don't think I have one but just another thing to check.
