I will look at that. I will put loop in the scangauge before the trip so I can watch it. Any other gauge that might be helpful?

Also, to make sure I have this right, I want to see closed loop rather than open loop? Closed loop uses the O2 sensor and the air flow to calculate fuel delivery and Open loop uses a pre-determined algorithm and is much less precise. Correct?

Since I have a 5-spd, I try to avoid WOT by down shifting before that is needed (I don't have cruise control). Especially climbing that grade, I down-shift into 4th to keep rpms in the power band (~2500RPM), I know this isn't the best for fuel economy, but i figure it is better than being WOT in 5th.
