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 …
