So I was trying out SHM the other day, (after 5 years lol) and trying to get a hang of it. I had to use the car's standard gauges as I don't own a Scangauge. I followed the suggestion on cleanmpg about pulsing to about 90km/h and then SHM-ing to 80km/h using the Energy Monitor as a guide (arrow from engine to wheel only. If there are arrows to the battery, it should flicker from battery to wheels from time to time). On the 2010, the red arrow for power from the engine is pretty hard to read at a glance so I was playing around with the HSI and seeing if I can find a suitable substitute. It appears that if you want to push SHM, 1/4-1/2 of the Hybrid ECO area (That would be the dark green bar on the left side of the HSI) is filled. You can go all the way to the midway point (thus filling up the Hybrid ECO area) if you want to maximise distance on SHM but use a little more fuel. Now I have nothing to confirm this other than guessing that I am in SHM and then looking at the HSI and corresponding what I'm seeing on the MID with what I'm feeling and seeing on the instant FE gauge (usually reads about 2.0-2.5L/100km or 94-117mpg US). Can anyone with a Scangauge confirm? it might be useful to Gen 3 owners that don't have a Scangauge to achieve SHM. TIA!
