Didn't know there is code for the ecu. Where did you went to change the code number? They should have some idea even before start changing it

hi frens,

i m just planted 4g93 came with 7377 ecu into my wira
Also having a same problem. turbo indicator doesnt work. my frens car with 5663 ecu turbo indicator is working.
i m now currently also facing another big problem, i sent my for for dyno test, when car standstill fuel is enough, when full trottle fuel is not enough at all. anyone here can advice, to change fuel pump or to install fuel regulator????

 

[AndyDemarco]

did u change the fuel tank or use back ur wira tank? ur wira original how many cc.
maybe the fuel pump on the stock wira tank have a low rate (l/ph)... try to change it.

 

[waikong_loh]

using gsr 4wd tank c/w fuel pump. any suggestion

 

[AndyDemarco]

theres a lot of possibility of running lean..
some are not enough fuel supply due to fuel pump failure, fuel line clogged or maybe injectors clogged.
try to put injectors cleaner additive or get them blueprinted if ure sure ur fuel pump is ok.

before investing on a fuel pressure regulator, try check the fuel pressure 1st by getting a fp meter, around rm50 sumthing. ur stock regulator (4g93t) should supply enough fuel unless the fuel pump is broken. (35-38psi idle, 38-45 psi throttled)

theres many other possibility also, regarding engine internal but this case have to be elaborated in more details. ;p
