(Wasn't sure if I should post here or to cleanmpg.com.) Ok, so I posted about being new to ScanGauge http://priuschat.com/forums/gen-ii-...uld-i-have-up-if-trying-optimize-mileage.html and tried reading thru the cleanmpg SHM thread listed at http://priuschat.com/forums/gen-ii-...angauge-best-threads-mileage-improvement.html and FE Ref Aid.pdf. I've been trying to experiment w/SHM and have a bunch of questions. Part of the prob is that I'm overwhelmed by all the info and discussions (coupled w/my limited free time) and I think SHM isn't suitable for the speeds I'm driving at. I think I'm able to use SHM fine above 45 mph and <60 mph. Holding IGN 13-15 is ok. Problems/questions: - At above lower speeds (~46 to 59 ), how hard should I accelerate? - What can I do about speeds between 65-76 mph, leaning more towards 68-75? If I use IGN 13 to 15, I lose too much speed. - At 65-75 mph, IGN 18 totally will not allow for acceleration. I can't even maintain speed at IGN 18. - Is it useless to attempt SHM while maintaing speeds of 68-75? If no, how hard should I accelerate? It seems like I'm well above 2000 rpm (I remember reading staying <2000 rpm in some post) and well above IGN 18 when trying to pulse. Perhaps I'm too lead footed? - If it's useless, is there another alternative method at those speeds? - I don't think know I how to properly get into "warp stealth". Not sure if I should care. Much of my commute is on a highway where the speed limit is 65 mph and driving 65 means you're going somewhat slow and will have to keep closer to the right. That means I run into all sorts of obstacles (cars merging, slowing to exit, and slow cars). That by itself would cause me to brake (wasting energy), not be able to stay in IGN 13-15, having to pulse, etc.
