I don't have a wide band...
Then... Ok, here is a pretty good one. You can see from the IAT reading, my dual/series sensor is currently in place; it reads 53.6 F. The system was initially stable, in a closed loop condition; look at the Short Term Fuel Subtraction ratio, it was bouncing between -10 and -13 percent with the fake IAT reading.
Then I jogged the throttle for a burst of momentary engine rpm; the loops status changed to Open Loop Driving mode, the ST Fuel Trim jumped up to KTM's patent OL behavior, the infamous zero line...
And even though I immediately released the throttle, and the system shifted back to CL mode, the fuel trim only gradually changed back to its previous condition [sub minus 10%].
20 seconds later [end of graph, sorry] and the fuel trim is still dropping/and the O2 still has not returned to active status [it's still stuck rich]... but you can kinda see where the ST fuel trim is still heading, right?
It's tied up in a series of videos I still hafta review [and screen capture], but it was actually going all the way to the -20 line [max enlean] and hanging there for a spell b4 going active again.
If it helps, as a general rule, 10% richer than stoich equals 13.36:1, 15% equals 12.78:1, 20% equals 12.25:1.
So it's basically like this: 14.7/1, or 14.7/1.1, or 14.7/1.15, or 14.7/1.2. Right?
I really gotta go, I'll check back later.
