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 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.
