S&S CYCLE Intelligent Spark Technology (IST) Ignition System Sensor — MAP sensor

Intelligent Spark Technology (IST) ignition system sensor enhances combustion control for improved performance and fuel economy. ⚡

• Uses crank position sensor, cam position sensor if present, MAP sensor, cylinder head temperature sensor and an exclusive knock sensor that detects detonation while the engine runs.
• Knock sensor allows the ECU to automatically adjust ignition timing to eliminate knock whenever it occurs.
• Optimizes power and fuel economy.
• The Intelligent Spark Technology ignition module requires an installation kit that must be purchased separately.
• Optional high-output coil available for variable fuel injection systems; the single-fire coil contains two separate coils in a single package, coil impedance 3 ohm per coil (sold separately).
• Made in the U.S.A.
• Not for fuel-injected models.
• Not recommended for kick start applications unless a cam position sensor is used; engines using crankshaft position sensors will be difficult to kick start.
• Modules manufactured after 10-1-03 (serial number begins with 'E' or a higher letter) include software to support the Guardian Diagnostic System; modules manufactured after 10-1-05 (serial number begins with 'G' or a higher letter) are compatible with 2004–05 models.
