And agree if you think it is shit, WHY??? Please state your reason fo the comment, cuz theres alot of people thinking its good and so you could prove us wrong, soooooooo..........



I think his statement is shit. how the fuck would he know if 1.6 octane points would remove the pinking. dumb ass mutha.

pinking is when your air/fuel mix pre-ignites. makes a tinkling noise. try optimax instead of the SUL your using. also when was it last serviced. when did you change your fuel filter last?

cause if the car is not getting the correct amount of fuel then that could lead to pinking.

like vibs said.. the timing can be a1 perfect but if your fuel pump or filter aint doing its job right then it can cause many prodlems, pinking for one, flatspots, idle prodlems... lots a stuff.

Wayne and anyone else the gsi wayne as was fully serviced(at vauxhal) as wayne said at 36k miles then had a full flush and engine oil change at 40k or just before.

Wayne have you put that superchip on yet? if not this may sort abit of the pinking out cos the lad at well-lane said it was running perfect as you can see with the graphs i gave you.

Darren

G/f misses that gsi ALOT

Pinking is when fuel detonates instead of burning smoothly.It generally happens when there's too much compression or heat. This can be excessive boost from a turbo or because the ignition timing is too advanced (ie the fuel air mix is ignited when the piston is too near the top of the bore, which effectively increases compression). If that's the case, you either need to retard the timing or use a higher octane fuel (which is more resistant to detonation under high compression/heat). On my 1.6 engine (which makes 214bhp), I've raised the compression to 12.2 : 1 and manged to keep the keep the timing quite well advanced to get as much power as poss. But it's mapped for Optimax. Anything less will cause pinking.
