WHP Wideband Knock Sensor Kit - M12 Apex'i as compared to the smallWHP wideband knock sensor kits are designed to take advantage of the sophisticated knock detection circuits in many modern ECUs, such as the ECUMaster EMU. The knock processing chip in the EMU is designed to take advantage of wideband, or flat response, knock sensors. Until recent years, most knock sensors were designed to generate an output voltage only around a preset frequency based on engine characteristics, limiting the need for signal
