Hi every body …

My spark rate is 14° @Wot what is the mainly problem I have? As I know that it must be 24°-26°

Note: I have knock rate of 3 - 4@WOT but I don’t think that is the problem of (14°) correct me.


Thanks

let me guess, you put in a huge cam, maybe heads, but you're on stock tune. so you moved your wot range like 0.20+g/cyl and car bogs badly, runs better at 3/4s throttle than wot, right?
you need to adjust your spark tables big time, watch which cell range you hit when you go WOT, and adjust it to your prefered values. how right that's gonna be is another story...

Yep

I'm willing to be he's also on the low octane table in addition of some nasty stock torque management kicking in if its an a4.
