Default at 0 throttle the o2s go lean and trims go WAY +

like the title says. no throttle sometimes the trims will go way way high about +50, stft. trying to figure this out but i dont know. maybe mess with dfco more? o2s go lean and trims dump in tons of fuel

Have you checked the VE table. I know someone with the same problem. VE table way off where we saw the trims go big.

Since you mentioned DFCO, are you talking about 0 throttle while coasting?

Why do you ask this? Is it normal if you're coasting? Mine does this.

yeah. everything pretty much zero's out while in DFCO, my trims either stop at 0 or read what they were showing before it entered dfco, ususally -1 -2.
