Description
Real-time knock detection and automatic ignition timing adjustment transforms how your engine performs under load—eliminating detonation while simultaneously optimizing power output and fuel economy. The S&S MAP sensor integrates with the Intelligent Spark Technology system to deliver precision engine management that carbureted performance builds demand. This is essential hardware for serious racers and builders who refuse to leave performance gains on the table.
The MAP sensor works in concert with crank position, cam position, cylinder head temperature, and an exclusive knock sensor to give your ECU complete combustion data. This multi-sensor approach allows the ignition module to make real-time adjustments that prevent knock and maximize efficiency—critical for high-compression, forced induction, or heavily modified engines where timing margins are razor-thin.
