ya sure need re-setup.. semput2 mean too much air suck to ur engine breath..
for good setup ur idle rpm must be at 1k rpm... if u are using hi-cam or 93 cams ur idle should be 500-600rpm or below than that..

perghh.. damn drunk.. myb u need to used AFPR and built up grounding cable.. look like ur electornic system not taily/match with ur fuel injection.. too much waste of fuel not burn in yours engine...
wonder everybody idle rpm used??? mine is 800rpm..

hmmmm but if u were to set 500-600rpm or lower for hi-cam or 93 cams....wouldnt that be too low? the engine will die off during idling....normally for higher degree cams..they will set it at 1.5-1.6k rpm...correct me if i am wrong....

 

[!!4g91!!]

oic.. but myb its depand on tuning for drag or road driving.. i seem someone car (friend) going for dragging/sprint at pgudang track at oni 500rpm or low than that.. hehe.. confuse sumore..

What is AFPR stand for?Is it working the same SAFC?If can improve a lot on fuel consumption why shudn't try install it..

 

[skyline_maniac]

AFPR = Adjustable Fuel Pressure Regulator

it allows u to set the pressure of ur fueling by adjusting the AFPR which is normally installed at ur fuel rail....whether to run at rich or lean.....basic fuel adjustment tool

SAFC has more function and mapping for u to tune ur air and fuel ratio...

no doubt ....AFPR is a good device to start off with =)

Yup agree with smaniac... that will be basic.. so easy to install and adjust.. make sure u got meter..
why SAFC if ur engine still maintain stock.. dont waste ur money.. hehe.. just sharing.. :shades_smile: :shades_smile: :shades_smile: :shades_smile:

 

[4g91ajer]

So how much it will cost to install that fuel regulator??Actually my engine kinda rojak already, did some mode which also contribute to fuel rich but i believe slight mode to the engine won't cause so bad fuel consumption...maybe mine even worse than turbo car:Not_Impressed:

gabai...
ur FC good ler....

got a person wif 4g91 in satria dat i know....
