MFG. Part #:
GTIN Code:


Second Strike is the only ignition system to providea powerful second spark throughout the entire RPMrange. Other multiple spark discharge systems typicallyrevert to one spark at about 3,000 RPM. The SecondStrike is a microcontroller based ignition supplement thatworks with most inductive type systems (points, GM HEI,Chrysler electronic ignition, Ford TFI and Duraspark, Ignitorand Ignitor II). Following the primary spark the Second Strikedelivers a powerful capacitive discharge second spark resulting inmore complete combustion. At very high RPMs the increased burn time canreduce misfires, resulting in more peak horsepower and torque.Second Strikes unique crank angle offset (CAO) feature gives you tunabilitythat no other box has. Simply turn the dial and change the time, in crankangle degrees, that the second spark occurs. A wide range of adjustmentgives you the flexibility to find which CAO works best for your engine.The integrated digital rev limiter features easy to use rotary switches, thatadjust the RPM limit to an ultra fine resolution of 100 RPMs, eliminatingthe need for old resistor style pills or chips. Proprietary algorithms providesuperior control of rev limit and a rapid response time to over rev events,preventing engine failure.Easy installation with a simple five wire hookup and detailed instructions. Nospecial distributor or ignition coil are required.
