Timing
#1
Just wondering how accurate the timing pointer is on the front cover of a S5 n/a. The reason I ask is that when I time my car correctly, I get bucking under light acceleration and a wierd sounding idle. If I advance the timing about a eighth to a quarter of an inch, this problem goes away and my car behaves much better, but I am worried about pinging the engine. Just wondering if there is any way to check this.
Thanks!
Thanks!

good luck getting your car to ping with an all stock fuel system , i can run mine almost full lean on the rich lean adjustment and my timing almost all the way advanced, i can get it to hesitate top end but not to ping.

Ok, so this might be a dumb question, but if I advance it until it pings, won't I break an apex?? The TPS was off a little, but by advancing the timing over stock, lets say about 1/4" (3-5 degrees??) the hesitation goes away and the car doesnt buck at all. Something else that is wierd, I am getting about 28-30 mpg on a large SP with headers and an intake on a 91 engine. AND it is fast.. go figure
