THis seems to work! I have hated the way the thing sometimes shuts off in when I cut the injectors... for three years or so it has been a frustration I just live with... I changed the value from 3 to 15 and it is better. I'll test for a while and maybe raise it further. Thanks!

results from kill switch

I'm using plastic wall switch kill switch on the shifter. My previous 2.7 mile route was 45 mpg cold and 62.7 warm. Now I got 63.3 cold and 81.8 warm with the kill switch.

The kill switch sometimes shows err instead of mpg. Changing compatibility > force mpg sensor to MAP didn't help. I will try adjusting compatibility > KWP/9141 optimize.

It would be neat to have a momentary switch that has an adjustable 2 second delay.

Using the kill switch throws off the run time, apparently because the ultragauge doesn't count engine off coasting time. Therefore distance / time results in the average mph being too high. The distance and mpg readings appear to be accurate.

Update: the ultragauge doesn't count distance when the switch is off. Therefore the mpg readings ( miles / gallons ) are too conservative when doing engine off coasting. This is a good reason to keep the switch off as briefly as possible.

I may be late but can't you just use a front fog light button? It would look 100% OEM, factory quality.

Right on! Thanks that helps me out. I was just putting up with the display going dead multiple times a trip. Adjusted and tested. Happy dance!

Do you mean the rear window defogger? I like the kill switch on the shifter,
but the defogger button would be convenient to use as a starter button instead.

No, I meant the area to the left of the steering wheel. Most cars will have at least one blank that can be replaced with a repurposed OEM button, for a nice factory look.

If you repurpose the defogger switch you'd loose that functionality. Better to use a blank space.

edit: not as accessible as the gear lever mount though, that much is true.

I wonder if it is possible to make a kill-switch for a '94 Celica

I would be shocked if it was not. Yours is a manual transmission? Those 90s cars are so much simpler in electronic engine controls and security that it is probably fairly easy. Find the grounding wire for the injectors make sure that cutting it will not cut anything else critical, then wire the ground through your switch. Done.
