I’ve been tracking down what it looks like to me a false knock, I’m pretty familiar with knock sensors and what and how they do but in this case I’m stuck.
Usually when the engine hears a knock event it’ll pull timing gradually until the knock is gone, therefore you see the “step ladder” graph. In this case, when I go wot tight after 3700rpm the sensor goes to +6 and stays there, no step ladder. It just jumps straight to 6 and it’s always around 3700 rpm
I got good gas, 93 plus a gallon of e85 and still the same
Also I should add the the car has 30k miles. Only upgrades are airaid race cai, occ, act tuner with strategy 93 tune passenger side
