PaleMelanesian drives an almost identical Civic. His is a 96 and mine is a 98. He wrote that his routine is a 35-45 P&G in which he seeks 75-80% load. Not more because the car seems to go into open loop. He drives mostly in fifth and on flat roads, I think. His discipline is tremendous. I have lots of hills, many quite steep. But I have been emulating him in every gear. I think it is a big help, but I can't reliably quantify it. The 612.5 mile tank was only 57.5 mpg, which is consistent with the last three tanks or so. BUT, I had a 48mpg average at about half a tank because of all the spoiler-testing and ignition timing fiddle I had done. I suppose I must have averaged 65/66mpg on the latter half of that tank. I don't think I can duplicate that because I am not willing to shut the car off at lights very often (starter wear). But I'm trying for 60+mpg and a 700+ tank this time. DWL is pretty damned cool if you get it down. But I have noticed pit-falls. First it can be easy to overshoot 80%. Second, every gear requires a different judgement as to RPM and %incline. But I monitor timing advance, rpm, throttle, and load on one screen. I never allow negative timing advance, and I try to never cross 20% throttle. I shift and drive in the 1500-1900 RPM range. I think it might be effective.
