LOF, I posted a second excel file just before your post with more spirited acceleration, Open Loop seems to kick in at 75% throttle and above, though this should require some more testing

I'm not sure you can get injector info off the OBD bus?

But what do you think of that URF AF sensor device I posted earlier? By tweaking the response from the sensor it would have the ability to affect the short term fuel trim and thus richen it up a little as needed. I'm just not sure how the rear O2 sensor will react to that and cause trouble...
