Hi all, I have been tuning my 20det and have into a bit of confusion. When I log the knock sensor values, sensor 2 is has quite different values than sensor one, even at areas where there is little knock possibility. Is this because they could be wired in series? Although wouldn’t make much sense, I haven’t looked into it much. I will get large knock spikes at about 5500rpm -6000rpm, we have taken a lot of timing out down to about 11-13* and ran different types of fuel and have had no luck. I would think that the voltages of the two sensors would be more similar but I could be wrong. I’m not sure if this is false knock or not but I would like to bump the timing back up to 16* ish as the afr’s were spot on and it felt good or if anyone has any other suggestions that would be much appreciated. Unfortunately don’t have access to knock ears. Cheers Set up is a rb20det gt2860rs 440cc injectors platinum pro
