Let’s investigate the situation a little deeper, but before we do that we need to revisit what knock is and what we are trying to do when we are optimising the ignition advance. It would be great if this was the case, as fitting a knock sensor to an engine prior to tuning can be fiddly and time consuming, particularly with a cramped modern engine bay. 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 tune the engine safely is a load bearing dyno with an accurate and sensitive torque reading.
Without 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.
