G4 KnockBlock The G4+ KnockBlock is an essential tool for tuning and can aid in the early detection of incorrect ignition timing, lean air/fuel mixtures and mechanical issues. It is used it with ear buds, headphones or noise cancelling ear muffs and features special filtering to allow you to listen in and detect knock early. Listen to one or two knock sensors Special filtering design improves signal to noise ratio Can be used with ear-buds, headphones or noise cancelling ear muffs Long life lithium rechargeable battery Rugged CNC aluminium enclosure Flying lead headphones connector Can be used with all OEM knock sensors Can be used to interface directly to a laptop for recording of engine noise or knock sensor frequency analysis (using PCLink G4+) Please note headphones with their own noise filtering may be unsuitable for use with the knock block. Includes: G4+ KnockBlock 2 sensor looms (attached) 1 headphone loom (attached) Quick Start Guide 1 USB cable mini 2 Bosch type doughnut OEM knock sensors 2 small Link Engine Management stickers Operating Install the knock sensor/s in a suitable location on the engine (typically on a solid mounting point on the block near the cylinder head) If only using one sensor, leave the unused sensor cable disconnected Turn the volume control clockwise until it clicks. The LED indicator will turn blue when the KnockBlock is operating Turn the volume to the minimum setting (most anti-clockwise) Connect headphones to the 3.5mm audio jack Run the engine and carefully increase the volume (clockwise) until engine mechanical noise can be heard. Adjust to a comfortable listening volume Charging Turn off the KnockBlock by turning the volume control anti-clockwise until it clicks Connect the USB charging cable to the KnockBlock’s Mini USB connector. Can be charged from any standard USB charger PC, laptop, car or cell phone charger (2.1A at 5V max) The LED indicator will show red while charging. When the indicator turns off the battery is fully charged Charge the G4+ KnockBlock after use and before storage

G4 KnockLink KnockLink is a self-calibrating, visual knock warning tool. The KnockLink is designed for tuning, street and race use. Will require a knock sensor to function (sold separately) or you can purchase the KnockLink Kit that includes the Knock Sensor and Loom. The G4 KnockLink is the only detonation warning device on the market that requires no setup. Other systems require time consuming gain, frequency and noise settings to be adjusted. Without proper knock listening tools, this can prove difficult if not impossible. The KnockLink requires none of this, just wire in and start the engine. Even light detonation will damage an engine over time. The G4 KnockLink's microprocessor continuously scans the knock signal and warns for any knock occurring. The engine's RPM and load is automatically 3D profiled by the KnockLink, continuously storing and dynamically adjusting this noise profile map while looking for the particular knock frequency. Operation is simple. The colour of the LED represents four different modes: Dim Blue - KnockLink is powered, waiting for the engine to be started Flashing Blue - KnockLink has detected the engine has started and is now calibrating Dim Green - KnockLink is adapting to the engine's noise profile and listening for knock Flashing Red - KnockLink has detected knock.
