Ping PIng ping Ping ... can happen if you advance it to far...especially how rpm high vacuum (mbar) tuning = correct timing and air fuel, a combination of both will revival greater benefits. But when you change / move the dizzy to advance your timing your putting advance everywhere, tuning puts it where its needed… ie Idle should be 16deg ;-) and low rpm high throttle should be negative / set ignition…… on a typical B engine.

Such a complicated answer. True that it advances throughout the entire rev range, but we're not comparing it to an aftermarket tunable ECU
I advanced my timing a coupe of degrees, ran PULP and got more KMs out of a full tank and there was also a slight improvement in power.
How do you advance timing without adjustable cam gears?
(other than the hanny's method)
start engine and wait til it is warm (or go for a quick strap!)
jump the service connector,
loosen the 3 dizzy bolts (leave the top one tightish)
grab a timing light, point it at the crank pulley, see what the timing is (you MUST look directly along the line on the timing belt cover) and adjsut the dizzy accordingly...
the middle mark is 16 degrees on my teg, the one furthest from the white TDC mark is 18 degrees,
which is what it is set at...
i can feel the difference
(oh - and dont forget to remove the service connector jumper!!!)
If you listen to tinkers instructions and run 98 octane you will be fine.
After all, its only 2 degees advancement, I sometimes apply more on the dyno, and anyone who has had any experience here will know just how timing effects the power curve.
i got a b18a da9 and the guy i bought it off said to only use 98octane is in, would this be because it has advance timing? and if not would advance timing give me much improvement??? my only mods are headers and catback....
