actually for those running external fuel pumps for the carburettors, they do have fuel regulators which are meant for use just for carbs, but uncommon...dunneed lah....better put the money elsewhere

hmmm not too sure if its suppose to be that high, even b18c set at 40 on idle..now that you're on 44psi...does the car feel sluggish? or is the any popping sound upon deceleration ?

at 44psi ok already but what worries me that the wot press not enough..
while deceleration also ok..
now running bigger injector.. 275..
will tweak around to find best setting..
if too rich then will try standard injector again..
really tiring to find the best setting for the engine..

Bro, i wanna ask something

i've set my AFPR to 3bar, but then i not moving(idling) and play with throttle. i see the meter is going down merely to 0bar normally when the engine rev going above 5k rpms(revving when idling lah..) never check when when i blast the engine....as meter in the engine bay... :hmmmm:

so far i had not pinging/detonation sound from engine... plug are abit black/brownish.

i think ur fuel pump is weak bro or ur injector is to big for fuel pump to applied adequate pressure.
i'm might be wrong.try n ask other sifu n see.:biggrin:

i think ur plugs might be foul or ur running rich.

i think your timing is advance which means when your valves are overlap a bit of your combustion happen when exhaust valve is slightly open this is called backfire..

I've changed plugs & the prob is still there.. and if im running rich.. my FC will suffer rite ?? but i dont seem to notice any change in my FC reading :hmmmm:

i think your timing is advance which means when your valves are overlap a bit of your combustion happen when exhaust valve is slightly open this is called backfire..
how can i resolve this ?? in the long run.. would it have any negative impact on my engine if i buat tak tau & ignore it ??

THANKS ALL BROS FOR THE HELP !! :adore:

You are using e-manage,maybe you can ask to tune a timing a bit retard,if that can't,try to adjust it mechanically by using coil distributor.

But i think most injection now are electronically,u go tuned for fast of coz they will put advance,more pickup,more power,more fuel and more money..:biggrin:

hahhah...

good one snail...

if you're using emanage and its already tuned and set for performance..i think its fine..in most cases cars need to run a lil rich to produce more power....i think i read somewhere that evenif you're using a bigger size in diameter exhaust you will experience the popping sound..(sifus pls correct me if i read wrongly)

some ppl do feel the different after installing fpr.they say their fc is improve.it's because
the pressure make the fuel spray by the injector finer and wider thus making the burn
more complete.

Gt i need to ask you something.

I felt my car FC was pretty good when i left it at around 29 at idle...but it did feel abit sluggish compared when i set it at 39 at idle.At 39,the car feels nice and smooth,easy to accelarate.but FC quite bad.

The question is....if i were to keep it at 29psi...is it possible that will cause my mixture to be lean?

Or will the ecu auto correct the fuel mix ratio ? If this is so,does that mean my FPR only serves the purpose of making sure the injectors spray are finer and wider?
