I got a 2003 AP1 with basic bolt ons, intake, header, decat and exhaust.
Have been doing some fuel tuning with the Greddy Emanage Ultimate now and think it's starting to look ok.
But I was wondering about the knock sensor readings I am getting is safe?
It's the yellow line in the picture, it spikes to 43% but is kind of noisy so I not sure if there should be any concern.


If you got the greddy software and want to look at the log here is the file: https://dl.dropboxusercontent.com/u/.../fullgas14.lg2


Here is the same run in Virtual dyno with some smoothing, compared to an old no tuned run.
