erm, SOCH or DOCH?

its a soch.

SOHC ler (single overhead camshaft)

If cam pulley is retard 4 degree, how bout d distributor? Issit also have to retard a bit? Have to set back using d timing light?

Btw, how's d FC if normal driving? Issit improve compare to stock?

distributor set at default lor... slowly do trial n error see which setting suits ur driving style... thats why i said this tuning requires vr delicate fine tuning.... not experienced person vr hard to see any difference....

my fc improved because my previous setting was wrong... (bcoz hand itchy diy tune till all wrong).... compare to stock of coz mine cannot win la... weber + highcam how good fc u can expect leh....

FINALLY! Admit also! Not stock anymore...

Yeah, I do my tuning myself as it always starts pinging when I get my mech to tune it. Even with the proper wide-band (my mech is also a Proton Service centre), the setting isn't always satisfying. A good trial & error run spanned over several days should give you the best result

weber + highcam also can be stock...

its called kiasu stock

technically, its useless in msia unless your tuner is really really good or u are doing a race with it cos i believe most mechanics here wouldnt take hours of adjusting it to maximize your car performance accordingly.
in msia everything is easy done easy go. ever wondered why those fuel saving gadgets/ voltage stabilizer can increase so many hp in overseas? answer is commitment and dedication

Malaysia? Kerja senang dan mudah

partially true... but their tuning experience aint fake as well... somehow they tune according to their feel, not through calculations and computers.... it is based on years of experience to achieve that....

as for fuel saving gadgets and so on, they are created by businessmen who knows mere tiny bit about cars and sell them to total noobs about car.....

they did? by how many Hps?

well they have dynos and stuff, which i believe shouldnt be fake... or else whats the point of selling it? sooner they will be bankrupt wat...

malaysia dun have dyno and stuff meh??...

got la dyno and all other stuff...but i dont believe all the fuel saving thinggy...better put my money on apexi s-afc or neo...

vr true...

Bro's, if any of you whom have done the adjustable cam pulley mod, could you share with us which cam pulley is the best value for money and which workshop that has the right tools & expertise in helping to adjust the power band correctly? Regards.

arospeed adjustable campulley....

workshop ah??.. dunno leh...

Bro catacombs,

thank you again for coming to my aid in ZTH forum where i've reappended below your earlier advise in order for the benefit of other members....

"yeap.. listen to sifoo tofu... start advancing 1 mark (2 degree) on the campulley.... then try listen for knocking noise (by revving when idle or test drive).... minor knocking is acceptable as high revving is not what u looking for... but major knocking is a big no no... soon it will damage ur valve seal, piston ring, or worse, create a crater in ur piston..."

hence, on the piston knocking issue, would it go away once i manage to get the optimum advance timing value/ degree or would it be a permanent feature even when the engine is idling or cruising?...

i now have second thoughts about this cam pulley mod as i was not aware earlier it would result in this piston knocking side effect...

await for your invaluable reply...

it will be a permanent feature... u can try using colder heat range plugs or higher octane fuel to minimize knocking....
minimal knocking is somehow still acceptable if u not a high revvy person (not everyday rev till redline) to maintain driveability....

thanks Bro for pointing out to us on this shortcoming cam pulley mod if one were to shift the engine powerband to lower rpm...i was about to purchase a Works Engineering Cam Pulley worth RM230 but upon giving further thougths, maybe it is not a good idea after all considering this knocking side effect...like they say - you can't have the cake and eat it also...better spent my money on the Boron Nitride thing...thanks Sifu...
