If you're worried, then 20 mph... but 40 is way to high to be useful. I think the Yaris/Corolla cut off is a lot lower than 40 to, which is why they have better fuel economy.

That is different. You are turning the engine completely off, as opposed to stopping the injectors from firing.

I could take me weeks to get a few mpg reads before I can do the cutting and see if I get better results. I get almost 2 weeks out of a tank.

Yes and no I guess... You *are* stopping the injectors by turning the engine off... but I take your point as I guess it might lug at 10 due to the power requirements of the alternator/electronic/power steering etc. But 40 is still too high for my liking.

If I'd have the duty cycle option on my digital multimeter, it would be very easy to find out when the injectors stop firing and when they start back up.

I was reading some GM document online that said 40... I'll try to find it.

So where do you get the "variable ohm 10 turn pot"?

Locally? RadioShack. Online I'd check out mouser.com or digikey.com.

Has anyone been able to increase their gas mileage, with this mod?

anyone else realizing the 6 year bump of this thread?
