Think about it folks. You are allowed to have a box with a computer inside of it that moniters RPM and TIME, and then controls the ignition timing, the shifter, the throttle stop, the trans brake solenoid, a 2-Step, and who knows what else. You don't have to be a brain surgeon or a rocket scientist to figure this out. NHRA and IHRA have to BAN these delay boxes and digital tachometers.
