Monitor Vacuum for Throttle Range in LB
Per Willie's recommendation the other day, I began to monitor Vacuum on my Bluetooth OBD II Torque app (free version) instead of just the Throttle position to see how much Throttle range is left before ICE kicks out of Lean Burn to maximize MPG. It took me a bit to get used to it, but it made a huge difference! I even managed to get up a 1.5 miles long hill on the freeway in 4th with LB and 60 MPH w/o Assist instead of downshifting to 3rd and 65 MPH w/o Assist as he had suggested. ICE comes out of LB when Vac gets below 3.5 - 5.0
Thank you Willie.

1st Photo; ~10 miles avg at 30 MPH on secondary 2 lanes. 2nd Photo; Continuing the next 40 miles on two lane state highway at 55-60 MPH. My best results yet. Normally averaging 70 MPG in AM and 80 MPG over~ 50 miles one way commute gaining 500 ft elevation in AM and losing it on the drive back. I try to keep Assist to minimum.
