Eliminate pinging and misfire in high compression and large displacement engines. Advance curves range from fairly steep for near stock to more gradual for high-horsepower engines. All ignition circuits are contained in the nose cone and there is an Accu-Ray static timing LED. Single or dual fire operation is switch-selected, and dual sensor circuits eliminate hard starts and give accurate spark timing even at high RPM. Eight advance curves, adjustable rev-limiter (6,000 to 7,500 rpm) and two VOES modes.
