As a professional tuner, effective knock detection is the single most critical aspect of tuning any motor - particularly in highly stressed, high boost applications. I have tried most of the knock detection products on the market over the last 8 years, and have found the KnockBlock to exceed the performance of the competition, while offering more features and a lower price.

For knock detection using the audio headphones, I found the KnockBlock allowed me to clearly isolate knock even on noisy engines. When used in conjunction with a G4 ECU, the KnockBlock can also provide active individual-cylinder knock control. We tested this function and found it to be easy to configure and highly effective, giving added peace of mind when tuning an engine on the edge.

In my professional opinion the KnockBlock offers a cost effective approach to knock detection, and since initially testing the unit I would not be without it. I have personally used the KnockBlock on everything from 100 kw road cars through to world-record holding 1200+ kw drag cars, and anything in between.
