A soft limiter in an Internal Combustion Engine (ICE) car is a type of engine management system designed to control the engine speed and prevent it from exceeding a certain RPM (Revolutions Per Minute). Unlike a hard limiter, which abruptly cuts off fuel supply or ignition to stop the engine from going beyond the maximum RPM, a soft limiter gradually reduces the power as the engine approaches the limit.
