Idealy you want 0 spark knock... so you want to tune to haveing spark knock and then back it off little by little till there is next to non... right? and to do that you add spark, which means you then have to add fuel to counter the extra spark or it will be stupid lean... I cranked my spark tables way up and my fuel to counter it and I still dont get spark knock in the normal rpm range of my tables, i get pleanty at high rpm side but no matter what I do ... no spark knock in the low rpm range of the table... as in up to 2400. Why no spark knock? I should be able to get some right?

 

I wouldnt get too carried away trying to get knock. On mine, it may or may not knock at certain speeds and loads. I usually end up just running rough at low speeds, loosing power , overheating, etc. if I have too much timing. Depending on where it is I may also see detonation as well. Try to pay attention to how the motor is running overall as you add timing in. Dont throw a whole bunch of timign and fuel in at once. Start in small increments and see how it does. G-tec helps with setting up WOT but P/T is almost all subjective, basically jsut setting it up the way you like. My preferences are no bogging while still running smooth and not overheating.
