I actually schedule an appointment with a tuner , famous for unichip located in jb - permas jaya.

I was pinning the hope that the reading, would actually tells what is wrong.
But for such an old engine, is it that advance?

If O2 sensor CEL should light up.....

 

[vr2turbo]

hey hey, checked.
with another air flow sensor, also the same.

with air flow.. 0.5
no air flow, 1.0

Why I mention air flow sensor, is because you remove can boost.....hmmmmmm?:hmmmm:

 

[mojo1ne]

Yes sensor issues shd light up cel but who knows.. Better to get it checked

CEL stand for check engine light?

Nope, I don't have this problem with the air flow sensor.

If I remove the air flow sensor, I will then have the CEL.

Formally the car already comes with CEL, the previous owner don't use air flow sensor at all..
but he has a SAFC 2 which I already sold it away.

Hmm... Is ur airflow sensor compatible? Previous owner changed anything inside?

He using back evo 3 air flow....previous safc2, so afraid some tuning or adjustment needed.
I thought he contacted you already....

Nope. . Safc already sold and use the money for other maintenance.

I was told safc don't serve much of a purpose in turbo cars..
