Kill Switch - Try this
http://ecomodder.com/forum/showthrea...c-12075-3.html

wiring info is on page 1, PGM-FI location for your car is on page 3

This mod cuts off your fuel injectors/ignition/fuel pump instantaneously. It leaves the ECU on, therefore, the car's odometer/trip meter/scanguague will continue to log miles.

You use this essentially with pulse and gliding...except now, you glide with the engine OFF. Basically its.

1) get up to speed
2) shift to neutral, flip the switch to kill the engine.
3) then bump start in 5th gear to start the car up again.
4) yes, that means you have to bump start every single time. But technically, you dont HAVE to bump start it, however, bump starting saves wear on your key/ignition.

On my usual commute to work, normal driving i get about 28-30mpg. When using engine off coasting, i get 38-40mpg. So, this REALLY helps.
