yong u noe where i can adjust back my a/f and check the O2

no ar...both dohc head also cost alomst same price onli wud...

go for dyno run at gt auto lah...rm 100 onli...then u'll know wether u r running rich o lean...

btw...wat injector ar u using..?
the stock 1.6 injector or the 1.8 injector?
if 1.8 injector then my guess its running a little too rich
if use 4g92p injector then not enuf power pulak...erm...y not try 4g91 injector...the injector is bigger size than 4g92p

 

[softmuffin]

GT auto Rm100 with adjust back the a/f or just checking only.
Using 1.8 injector now(240cc). already install the afr but i think i need to adjust
the a/f setting.

oh..u using 1.8 injector now then reduce the pressure a little lah...
might be running too rich edi...
too bad i dunno wats my bro ori 4g92 dohc injector size...if not can help u...
rm 100 is for dyno run n check air fuel ratio also...erm...mayb he can help u tune a bit loh...last time he also help me tune a bit...

 

[softmuffin]

yeah, i hav try reduce the pressure still same. the fc still will be full tank 300max
no matter how low i adjust the pressure.

i think the 2pid a/f ratio is all mix out already.

[Yong_5290]

do u smell lots of petrol out from ur xhaust?
i think u r running too rich wit ur injector...y not try swappingg back ur 4g92p...
if not u need SAFC to tune...

 

[boyzone]

4G92p is 187cc and 4G93 injector is 240cc , sure u will run rich .. :D

ecu just follow mapping to supply fuel, but it dun know how how big injector u r using :D

 

[Yong_5290]

yea..i think 4g91 injector should be just nice for ur setup...since the 4g91 injector size is a big bigger than 4g92p...
or is u r good enuf then can find for 4g92 dohc

 

[kher]

No need dyno run 1 also can check 1....
Go to GT Auto n ask Thomas the friendly do the lambda test for u. Then from there can c ur A/F ratio in the monitor. Then he will tune it to the correct amount for u.

I did mine tat time less than rm100 i think (total add up with changing spark plugs, compression test)...
