Karman on a S-AFC??

[jyang8]

i know dsm are karman type, but what i don't know is how do you read what karman means on a S-AFC. someone once told me not to exceed 1800 hz, but everytime i pull my car it reads about 2300 - 2400 hz. does having such a high hz reading contribute to my car knocking? someone please tell me how to read the hz on karman and what it means. what is normal?

car mods: 660cc injectors, fp green, tmo stage3 (no fuel cut), lots others

I hope not, I've seen those numbers at WOT around 4-5k. I haven't made a redline pull since I put the afc in, but I'm guessing I'd be WELL over 2400hz.

can some get back at me about what and how to read Karman on a S-AFC?

Are you still on a 1g MAF?

Although hz reading is affect by alot of variables, 2400hz is out flowing the 1g maf.

Also to mybeatgsx if your seeing that many hz with those mods you have a boost leak.
