Ion knock detection

WebWithout a doubt, knock is easily the biggest killer of any performance engine yet it’s still largely ignored or misunderstood by a large percentage of tuners. I’ve been a strong advocate for using quality audio knock detection on any tuning project for as long as Ive been tuning, but there are a number of tuners who disagree, stating that all you need to … Web2 dec. 2024 · Knock-sensing is a valuable tool for tuning det-limited fuels, but ion sensing would allow tuning directly to best timing (any fuel), and detect det as a secondary function. The primary issue at this point is not technology, but the general public impression that knock sensing is a protective device, rather than a tuning tool.
