Here's my first attempt with preliminary data from seven runs. Details will be presented at HybridFest. Speed limit: 35-55 MPH 46.1 MPG 32 MPH Av P&G: 38-15 MPH 78.9 MPG 23 MPH Av CC: 23 MPH 67.1 MPG 20 MPH Av P&G: 40-25 MPH 66.2 MPG 27 MPH Av CC: 29 MPH 73.3 MPG 25 MPH Av P&G: 43-5 MPH 62.3 MPG 22 MPH Av CC: 25 MPH 76.6 MPG 22 MPH Av Summary: P&G in this range is more efficient only within a certain range (in my case determined by setting the pulse range by the IGN [ingition advance] readings on the ScanGuage. At the fifteen MPH and Max Pulses, cruise control is more efficient. This data is surprising to me, and I intend to make another set of runs.
