WHP 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 processing. The drawbacks of such sensors were their inability to separate knock from noise. With modern signal processing, wideband sensors can be used, allowing the EMU to process the signal in its full range and look only for sounds that actually represent knock. The EMU is also able to filter the signal by crank degrees so that it only monitors the sensors at engine positions where knock is likely to occur. The use of WHP wideband knock sensors allows for greater sensitivity to knock and greater control of the engine, allowing the tuner to maximize power output with the confidence that the EMU will employ engine protection strategies when knock is detected.
Each kit includes a new genuine Bosch knock sensor with 12 month warranty, titanium mounting stud, retaining nut, and electrical connector with terminals and seals.
Flat response knock sensors can be used on virtually any engine, but please check thread diameter and pitch before ordering. The stud in this kit is M10 x 1.25.
