How can I make an adjustable rev limiter for a MSD CD ignition?
I have a MSD HVC cd box and coil. The MSD box uses pills to cut off the ignition if I exceed X amount of RPM's. To change it, I have to pop the hood and change pills. I think the pills are resistors. How can I make this where I can set the rev limiter from inside the car like I do the shift light?
