Is there an adjustment for the point at which the assist kicks in? The best I've gotten on a tank for my 2000 Insight was 67.7 I usually get 57-61mpg.

Lately, I've noticed that when using assist in 5th wide open, the gas mileage drops to about 40. It used to never frop below 49 in 5th gear. Anyone hear of an adjustment for this? I do onsite computer repair and just hit 90,000 miles today but running great otherwise.

Any idea where I can get skinny rims that'll fit under thoughs covers?

Thanks guys and gals!

AFAIK there is no adjustment for the electric assist except to raise your right foot. :)

67.7mpg is very respectable, but you can do better if you try. It requires slowing down a bit and driving by the instant MPG indicator, letting speed vary by traffic and terrain.

My experience with my best MPG is to use little or no assist on acceleration and let speed vary by no more that +-10mph. If I choose a route that allows speeds in the 55mph range I've held 80+MPG even in these hills of east Tennessee.

The Insight's rims are full size 14" rims that are 5.5" wide (that's common). Good luck finding rims that are anywhere near as light weight and aerodymic as the OEM Insight rims.

Actually, I'm getting a crazy stupid voide the warranty idea here. From what I know the assist works off of manifold pressure. It falls, ie you give it more throttle, it kicks in. I rememeber a few years back I got to play with putting those supre chips in some F-350 diesel trucks, and boy did those things make a difference. Along with the chip though it came with a small metal fitting that you put inline with a vaccum hose for the turbo and it actually created a vaccum leak which made the turbo kick in much earlier. So shouldn't there be a way to create a vaccum leak that would cause you a much more aggressive IMA? I could be wrong on this, but my mind is thinking this way today.

Well, I'm not going to try it here. The ECU in the 2002 is already way more aggressive that I would like it to be for the summer and I don't really want to kill the batteries that quickly by having full assist at every light. Can we say recalibrations? But this is only a theory of mine, you'd have to look and see how it operated before you could even say it could work. Have fun, standard disclaimers apply.

Electrical adjustment

I think you are probably on the right track Ricky. According to my many many miles of testing with and without the Turbocharger I have used a vacuum gauge on monitoring the engine and associated parts. It appears that "most" of the time the IMA kicks in at "0" in. of vacuum, especially in the higher gears. (3.4.5.) Have fun........Keep working on the "task".

Yeah so a little tiny pin hole might just do it. Actually some sort of variable valve would be about right as you could adjust how much vaccum leak to create. Again, I wouldn't do this as if anything I would be looking to decrease assist where I live. Getting a recalibration while climbing a relatively steep hill with the AC on today like I experienced was not exactly what I call fun. But, just be careful you don't create too much of a vaccum leak because imagine it if you were to have assist trying to be on all the time, what a mess that would make.
