KnockBlock G4+ (KNB)

The Link ECU KnockBlock G4+ is a dedicated knock detection module that extends G4+ ECU capabilities with professional-grade engine knock sensing. Supporting up to eight individual knock sensors, the KNB processes audio frequency signals in real time and communicates directly with your G4+ ECU via CAN. This allows sophisticated knock detection strategies across multi-cylinder engines, with per-cylinder monitoring and programmable response parameters. Ideal for high-performance builds where engine protection and tuning accuracy are critical, the KnockBlock integrates seamlessly into Link's G4+ ecosystem without consuming analogue inputs.
