Pawtuckett, I have a 94 EX 5 speed I just picked up. I installed a kill switch relay in the injector power lead(s). I hope to have a mpguino installed soon and will let you know if it behaves differently than the pgm-fi kill. With ground to the pgm-fi unit disabled, the guino injector signal might be sort-of floating, so there is a chance a different kill switch will fix it.

It might need a pulldown resistor too for more accuracy if it isn't pulled low by default, or otherwise a couple bias resistors so it reads correctly when the fi is hooked up or not.
