Hey chaps,

been searching but can't fid a definative, can I road tune the spark table without a knock sensor? Is it just a matter to push the advance see when it knocks a bit then back it off or what??

Cheers
Rich

What you want to do is keep increasing timing till HP reaches a plateau...then back timing off till HP starts to decrease. This sets the timing as far away from knock, while providing peak HP. I assume you are gonna do this on a dyno?

I was hoping there was a way to road tune it...
