Hey guys, like the title says, I'm currently being etuned by one of our esteemed forum etuners and am at a critical juncture: no matter what is adjusted, knock registers at 2-3 counts randomly in every single wot log. Stock tune: knock. 11psi: knock. Retard mivec timing: knock. 11.3 afr the entire time, nothing is out of line which leads me to believe something is rattling in the engine bay. I'm left with essentially two options: throw the car on a dyno and have each cylinder listened to for actual detonation, or up the octane (93 here already in lovely GA). Problem with the first option is dyno time can't happen until 9/16, and no shops around here answers their phones on Saturdays. You guys got any solutions? Thanks!

 

What does your timing look like? Are you checking knock voltage?

 

Timing is maybe 10-12, can I watch knock voltage through evoscan on an Evo X? I don't see it as an option to log.

 

Bump your octane 4-5 points with this. That will tell you if its real or not..

I have my customers put a high octane fuel in then do pulls.
