I have done a good bit of research on this topic but found none that matches mine.

Well I have a 03 evo 8 fq300 with 330 piggyback ecu. It has 61000 miles and it also has a stock motor. The only upgrades I have is an apexi induction kit and evo 9 gt turbo.

About a year ago I had the head gasket replaced, and while the mechanic was doing it he replaced valve seals and cam seals. There was no problem with the head gasket since then that I can see.

I have also upgraded to the evo 9 turbo recently, about 900 miles ago. There was two main reasons I did this, I found the car was using a bit too much oil and thought of upgrading the turbo for reliability.

I though the old turbo might have had bad seals and thought the new turbo would have helped but it doesn't seem to have The car is still using a bit too much oil according to a mate of mine that deals with evos and I can see his point.

On start ups there is whitish kind of smoke but it normal, however if I rev the car especially when its not fully warmed up a lot of black smoke comes from the exhaust. I know you shouldn't rev a car when its cold but I give it a few mins. Also when I hit boost for the first few times after start driving it launches black smoke. It seems like oil is seeping down into the cylinders, would I be correct? I had a compression test carried out on the car and all cylinders have prefect compression.

Any help is appreciated guys

 

Too rich will cause bore wash which in turn causes oil consumption .

 

I was told that my ecu is locked on account of the factory upgrade, any info on this?

Cheers

 

I don't drive mine daily usually just in the weekend and mine is the same way. If I get on it While it has been sitting for a while i get black smoke, but once it clears out then it's fine. I figured it was normal lol.... Mine does not use oil though.

 

can be unlocked get rid of the piggy back and get it mapped, where are you located .

 

I pm'd you there
