Hi guys.
As some of you may remember I have a race kart chassis with a 94 F2 motor bundled into it. I have it running and ready to ride, but I am also designing a button shift kit for it. With this whole circuit, air cylinders will fire and complete a shift, but will also kill the ignition at the same time on the up shift.
To complete the timed ignition kill, I was wondering if I could power the side stand switch only for a moment and then let it go back to ground, or will this mess with the ECU and put out all kinds of errors?

Any other ideas on how I could temporarily ground/kill the ignition would help as well.

Thanks for the help,

Cal

 

Check out how quick shifters work on bikes. My guess is they use a function to kill the spark, but after the ECU to keep voltage surges from frying the unit. The side stand switch kills power to the ECU to prevent it from running at all.
