Hi-
I'm working on a small little project for my racing motorcycle. I am looking to make an adjustable momentary switch to interrupt the ignition circuit, to allow me to make full throttle upshifts while on the track.
A couple of examples-
Powershifter2
Techtronics Quick shifter
TECHTRONICS PQS3
I know that I can buy these, but why not make my own?
I have tried to use a carefully adjusted mechanical momentary switch on a bracket, directly inline with the ignition circuit, but I couldn't control the duration (or exact location) of the switch activation. So, my thoughts are that I just need to get a trigger to send a signal to a programmable/adjustable momentary, which would then interrupt the ignition for a predetermined length of time.
What parts would be needed to produce this in the smallest space possible? It needs to run off of 12v DC (+/- 1v).
Oh, the ignition circuit is normally closed, so I would need to open the circuit for 20ms to 120ms.
And, if this isn't feasible for a shade-tree mechanic, tell me. Or don't.
Thanks,
phil
