The Knock Analyser Pro (KS-Pro) is a high quality knock detection kit that allows the user to listen for knock whilst tuning an engine. The KS-Pro has been developed with the assistance of the UK’s premier tuning companies and as such contains many features lacking from alternatives on the market. The kit contains everything necessary to listen for engine knock. The KS-Pro can also be plugged directly into the Phormula KS-4 when purchased with the KS-4 Interface Kit to provide a combined audio and digital knock detection system.
