waah...so powerfull!!! I tot japanense only reserve good thing for themself...maybe they purposely drop 4G91 power for japan spec for environment friendly

Hmm, its hard to believe as even reaching to 180 also my RPM already at almost 6k RPM oledi.. however still possible provided the road is long enough, and the gear ratio is longer ler.. but still susah wanna input into my head ler..

 

[badguy]

party how ur extractor perform??
feel 100%???
hahaha
long time didn't post liao!

still don't dare to try 180 lah

badguy, your car got problem or what? my car auto easily hit 160km on 3rd gear @6300rpm, if I wanna go faster I just release throttle let 4rd gear and hold on about 70% throttle to let it reach 180km/h, and it is reasonable fast to reach that cause my car is auto.

Maybe you need send you car for tuning

partyJOE, I forgot tell you you need to unplug the battery to reset the ECU, something to share how to reset, first unplug -ve, then go inside your car, press brake about 1 minute to fully decharge the electric stored inside ecu capacitor, then plug back, drive your car like mad man about 10 minutes in various speed, then your ecu will reset back back on the new signal from MAF sensor, did you get what I means?

MAF better than MAP because it is able to detect air flow changes due to exhaust upgrade....hehe

No la, we are friend ma., sure have to make sure they do it nicely

bro.. i reset aredy... but the method alil different...
i unplug the battery overnite... then morning plug it back...
start engine n let it run for like 15 min(not driving)...
during this time, i c man idling go hai wire for like 3 mins...
then it slowly stablize by itself...
it resets at that time....

 

[badguy]

i think my engine should be no problem gua!!??

only i didn't tarik kau kau the engine before change gear

if i tarik every gear to 6.5k i think to 180 should not be problem
4th gear not yet 100km/h i already change to 5th gear already
kekekekek

i just dare not to do that (engine sound like to boom)
also scare kena saman the kena go to court somemore!
