PLEX KNOCK MONITOR® V3

The World’s Best Knock Detection Tool. Coming Soon.
full re-envisioned | hi-fidelity | build to last

Announcing the new, fully re-envisioned PLEX KNOCK MONITOR® V3, a professional hi-fidelity knock detection tool for the data-driven tuner. The new version comes with fully re-designed electronics, hardware and UI and brings a whole new level to the process of identifying and analyzing detonation on any IC engine. A set of new features and algorithms powered by a multi-core main processor with dedicated audio DSP allows one to pinpoint knocking on a cylinder level like never before.
