I'll try to find that in the thread.

I'm pretty new at all this stuff, but, when you say "closed loop running", what feedback signals are you referring to when you use that term? There are throttle position sensors, O2 sensors, speed sensors, air temperature sensors, etc. I am assuming that most of these are used in the feedback loop for AFR output, but, if you disable the O2 sensors, is that still considered to be closed-loop since not all the required feedback is being received? Also, are there times when the system runs open-loop?

Maybe all this stuff is covered in the TuneECU thread? If so, I should probably get to that soon. Just need to find the time.
