I would assume it would be load and commanded load/throttle position..

in determing when to change over. ECT would most likely play a small part as well.

Ever log block 054? It shows you in what mode you are in.

Over-run, Idle, Part Throttle, or Enrich.

I assume that Enrich is open look and all others are closed. Log that along with a block that shows injector on-time/load and you might be able to conclude something.

Gotta leave the desk, but I'll return to this. maybe post up a log of 054

Logged, nope. I really haven't played with this car too much.

But are you saying that the LTFT numbers change at WOT? Or they chnage from what they were previously?

I would go test this later but seeing on how I haven't driven my car for two months now it would be difficult (should hopefully have it back this week).

LTFT 032 "on" position values still remain the same as part throttle logged values....

but when going WOT, you see totally different #s for that short period of time. Once you go back to closed loop, the part throttle #s return to where they were previously. At least this is how I remember it from when I wasn't quite as smart and would literally log 032. Hold on while I check my logs, but I bet those old school logs were lost when my last hard drive took a crap.
