I have a Boosted Civic R18 that has been dyno tuned and the AFR is spot on at 11.5 However i noticed in the flashpro data logs that as soon as i turn the engine on the knock control is at 100%. From what ive read online about how the knock system works on these cars is that at 0 % knock control the ecu would assume 95 octane and 100% would be 85. I only run 93 octane in the tank, so if i have 93 octane why is the ECU off the bat jumping to 100% knock control and what can i adjust to bring it down? I dont believe the engine is actually knocking as i have not heard any pining nor have i seen the k retard go past 0. The car pulls and drives fine and everything is in the green on flashpro except the knock control.
Sure, Here is the tune and 2 datalogs from driving this morning. Thanks for the quick response
