Hi all Tonight on the way home the car and I were very close to one. I started seeing that with a very small input on TPS, that I was able to maintain 40-55 on state highway(non-interstate). I remember reading about the SAHM on both the Prius II and the HCHII. But I was never able to see anything like that until tonight. The idle TPS is 12 and if I was able to maintain a value of between 13(Near impossible) - 16 or 17 (very repeatable), I noticed that I was getting expected values of mid to high 30's. Now the real fun begins, I started to finesse the gas pedal as work on the IGN values. What I saw was really astonishing is that as IGN moved into the mid 30+ to approximately 40-42, I would see a really impressive gain in instant MPG. I would like to try to repeat it again but this is what I saw: TPS, IGN Instant MPG 13, 35 90+:banane58: 14-16+, 40 65+ The reallly cool thing about this technique or feeling, is that the car seems like it is willing to go into a high ign value from about 25mph. Now is this a technique or is it that I am starting to get it .... Please send some comments my way.... Now for the results: Segment 32.8mpg over 20 mi --- Imagine what it could be if I had paid attention to a few of the lights... Tank is up to 29.4 over 200miles not at the half mark yet.
