Wayne,
Graham did a great job on the scanner. It can display 4 items at once. I used the %load, % throttle, RPM, and current flow. I believe he has 30-50 items that it can read. The downside is that it doesn't work on the 04 Prius or the Insight. As a result I havn't tried driving any distance in the Prius but have had some short trips around time that were in the mid 60's. The 01 doesn't have cruise control so I took my turnbuckle and rope from the Insight to hold a steady throttle load. Just got my 4th 1000 mile tank this year in the Insight. The Lmpg moved up to 89.7 so the next stop is at the 90 lmpg mark. I figure I will be there before I hit 100K miles. Have fun, Rick
