I have to watch my scangauge very closely in my B2300/Ranger truck to keep out of open loop. At low rpms like under about 1800 I can nearly floor it and stay in closed loop. LOD can be at like 98. But as rpms rise the open loop comes in at lower and lower LOD readings. At 2300rpm on the freeway open loop occurs at about 65 LOD. I usually run about 45-55 LOD on level ground so it doesn't take much to go to open loop full rich and kill mileage. No WAI on this engine.
