So, you are saying that the way to kill the injectors is to open the actual current path of the injector and that the easiest way to do it is to open the 12V side? My cigarette lighter idea would fly in that case.

Does anyone know if there is a way to shut off the injection signal so that the ECU never tries to fire them? Does the ECU fire them directly? I would expect that it did not. I would think that it would have a very low current signal that told something else to actually fire them.

thought I'd give this a bump.

Tried asking the same question on a Ford Ranger board and all I got was the typical responses.

Hypermiling is stupid and dangerous.

It's a truck, your mileage is supposed to suck. Buy a prius.

Gotta love it when somebody with a lifted bigfoot wannabe truck tells you that your hypermiling is dangerous.

Anyhoo, I think I did a pretty good job defending the honor of daredevil hypermilers. Always love a good interwebs throw down, even if I am greatly outnumbered.
