Boost issue

[h3nno]

Hi,

I have a Mitsubishi Galant with a 6A12TT motor.

When I increase the boost to around ~16 pound and the weather is cold the car will occasionally not fire and loose power then pick up and lose again, dumping big clouds of black smoke - unburnt fuel.

But when its a hot day it is silky smooth. Any ideas what is causing this?

Thanks.

Yep as i said get the car tuned. You increasing the air pressure. The ECU is like WTF. And its shitting its self.
Pretty sure this cars run like 8 PSI stock. Boost it max to 12 without a retune

Btw its actually a 6A13... 6A12 is the 2L V6 MIVEC in the FTO GPX/GPR...

Your ECU is going into limbo/safe mode. this has detected an increase amount of boost pressure. Meaning that there is a huge amount of A/F ratio required (probably running rich/lean too) and your knock sensor has also detected pinging. This is the reason why your getting black smoke everywhere and the engine cuts out ...

Long term Overall status = ENGINE WILL CEASE.

as from everyone said - get your ecu reflashed/or replace with after market.

oh and this is a Honda forum aswell. :)

good luck.

I am glad you can use google. 6a12tt comes with three different turbos stock ranging from 4, 6, 8 psi stock and 14, 16, 18 psi free spooling respectively.

Incorrect the 8th Galant and legnum comes with the 6a13tt. The 6a12tt is JDM only. tt meaning twin turbo.

What Galant you have then? E84A/E74A? Would help if you actually give us more information than playing Guess Who.

I only knew of the 6A12 V6 2L in the FTO... I don't know about the older Galant/Legnum, never bothered with then...

I know what the TT in 6A12TT is just like the 6G72TT, RB26DETT, VR38DETT, etc etc etc

[Rage King]

^^ u forgot the VG30DETT :D

[DreadAngel]

ROFL, VG30DETT is covered in the etc etc etc XD

Colder day means more dense air. Either tune or you could buy a boost cut defender or something like an eBoost to keep the boost below stock boost cut.
