Used KNOCKLINK used from the TTP-Engineering shopcar MR 10.9 @ 129.94mph.

KnockLink is an LED bar graph display designed for monitoring engine noise, particularly engine knock (detonation / pre-ignition). KnockLink can be used with almost any type of factory knock sensor and has a built in sensitivity adjustment to allow the display to be tailored to any application and engine noise level.

Most modern engines will already have a knock sensor fitted as standard, but any type of knock sensor may be fitted as required. The sensor is normally screwed into a boss on the engine block although some manufacturers fit the sensor in the inlet manifold (especially Ford). In either case, the sensor must be in such a position that block vibrations are coupled to the sensor.

Assuming the engine is operating correctly, the LEDs will show only background noise which will rise in proportion to engine power output. Any abrupt rise in signal level at any time is an indication that detonation is occurring. Early detection of severe detonation can help prevent engine destruction.

Whether installed permanently or used as a temporary diagnostic tool, the KnockLink can help detect detonation / pre-ignition, optimise advance and prevent costly engine failure.

Specially modified for voltage output logging to zeitronix, logworks or any other logger with 0-5v inputs.

Just add knocksensor. Bosch sensor recommended.
