Kill switch how-to

My 1999 Honda CRV coasts right into 'Fuel Cutoff' when I take my foot off the gas on a good hill (while in 4th or 5th gear).
The Scangauge2 starts displaying 9999.9 MPG.

If I'm coasting down a smaller hill and engine braking is just too much,
Or, I feel the need for speed!! Just shifting into neutral and
letting the engine idle nets me around 50 to 70 MPG while coasting at 30-40 MPH..

Coasting while in Fuel-cutoff is super simple and can be done without doing any wiring..


That SC2 is a great little device for showing how much gas you are wasting going up hills too fast.
I've been using it with the Cruise Control for highway driving.
When I see the display dropping down around 20 MPG going up a hill,
I back off with the CC down button. On the down hill part, I use the
CC up button to apply more speed until I see the MPG hit a peak,
or until I hit the safe speed limit.

I love good long hills where I can hit 65 MPH while getting 40 to 70 MPG..

Thanks for the info, bbjsw10, I'm following the thread closely. Impulse, as an installer, have you run across the sockets for those Bosch style relays? I have used those to make some of my installations a little cleaner.

Your welcome.

I was lucky enough to find a very slick control knob at the junk-yard today.

It is a joystick from a forklift - cast aluminum with TWO momentary one switches built it.

Perfect for both a kill switch AND a push-button start. Plus, it gives the feel of a jet-fighter!

Sorry no photo. My camera batteries like to die at exactly the wrong time.
Will post one later.


Edit: Hey, just remembered I have a web cam!




Cheaper than THIS and at a much better price.

I gotta see this, sounds pretty bad-a$$. What ride you putting it in?

Planning on using this stick for a kill-switch setup in my 4-banger Chevy S10 pickup truck.

Just saw the picture, I WANT ONE TOO!!! My car is starting to look like a shuttle might as well have a flight stick..

I should do a writeup of my ignition coil kill switch method. It would be interesting to compare the two methods to see if there's any difference in the way the car stops/restarts.

Would the fuel system keep pumping in fuel if the car is moving in gear with the ignition killed?
