Item Details

  • Manufacturer Part No : 55-1221
  • The S&S Intelligent Spark Technology ECU module automatically adjusts ignition timing
  • When detonation is detected by the exclusive knock sensor, the ECU retards the ignition timing to prevent engine damage
  • When detonation is not present, ignition timing is advanced for maximum power and economy
  • The system ’remembers’ the conditions that cause the engine to knock and automatically adjusts ignition timing to prevent it when those conditions reoccurIf a different camshaft is installed or if cylinder head modificationsare made, the S&S Intelligent Spark Technology ignition system will automatically optimize the ignition timing for the new configuration
  • No timing adjustments-the system adjusts timing automatically
  • 7000 rpm rev limiter
  • Single fire operation-requires 2 coils or dual coil package
  • Short circuit and reverse polarity protected
  • If major engine modifications are made, such as the installation of a stroker or big bore kit, the system will adjust to the ignition requirement of the engine
