Can someone help with this knocking problem that only occurs when I go too full thoddle very quickly. If I ease into the throddle slowly, I can have full boost without any knock. Has anyone else had this type of problem before?

Thanks,

Brent W.
 
Thanks, that might be some of it but I also have too run 10:1 AFR most of the time when past 10-15 psi of boost to control knock. I'm also running 100 octane Av gas, so it seems like knock should be low no matter what I do. This however is not always the case.
 
I would sell your programmed chip and get dsmlink. Then you can use the timing sliders to take out a degree or 2 in certian places in your timing map. Problem is the 1g ecu already has really aggressive timing maps and since your running 9:1 compression over the stock ratio your problems are amplified. Stopping knock by riching up the mixture has limits.
 
I have a less aggressive timing chip that Jeff gave me along with the more aggressive one that I'm currently running. It's just that I really liked the low end responce this chip has. I will give the other chip a try it to see if it helps.

Thanks,
Brent W.
