Whats your timing?

Ok I'm having some trouble with pinging (I think). I have my base timing set at 10* and I'm hearing some thing I fear is pinging at only 7psi boost. I have a wideband and AFR's are rich if any thing even if I tune it to 10.5:1 can still hear this ping. This with 94oct! I'm using the maf-pro by the way. Timing under boost is between 24*-27* dose that sound normal? Will the ecu see knock in open loop?

Or what other thing could I be hearing under hi load full boost that makes a kinda hi tick tick tick tick tick sound?

Any thoughts would be appreciated!

Open loop and closed loop do not change timing. It is for fuel control and the cat.

You can get a tank of gas every now and then that isnt real good. Check for codes. The newer ones, don't know when the switch was, have a code for no knock control. Seems like it is a 53. Then you will know if you are pinging.

the knock sensor is working I don't have any codes. I still don't know if it is indeed pinging when I get on it but if some one could tell me how much timing the ecu pulls when it sees knock then I could tell by my logs. If the ecu only pulls 3*-5* then it is proly ping that I'm hearing. But if the ecu pulls 10* timing then is not ping that I'm hearing.
