Knock with 94 octane
I'm running the DS 91 octane tune with Cheveron 94 fuel. I'm getting 3 degrees st knock at rolling WOT. I've attached my data log and looking for advice thanks...

I've now also done some 0-100 WOT runs with 2 deg of LT and 6 deg of ST on the 91 tune with Cheveron 94 octane. Any advice??

Re: Knock with 94 octane
Unfortunately I can't view anything I log right now because I only have access to a Mac, my Pc is at work and I wont be working for awhile. I do have a catch can installed. Were you able to open the older log file I posted (cruise WOT)? I was having issues posting before but changed it to a zip file as per your recommendation.

Re: Knock with 94 octane
what vehicle is this?
May have excessive oil build up in the intake manifold, time to clean it out or wait for it to burn off and hope the catch can keeps more from building up.
