Can someone please take a quick look at my tune, I made very slight changes to B6215, B6220 & B6221 in an effort to encourage the computer to move towards the high octane table since I always run Chevron 93 premium. I noticed in my log that it is using the high table 100%, but when it hit KR of 1.8 degrees, it did not move at all in the direction of the low table (stayed 100%). Would like to make sure I did not hinder the ability to effectively move in the direction needed to avoid repeated knock and retard. Or is a few isolated 2 degree retard too little for me and the pcm to be concerned with? Thanks, tune attached.
