The issue is that even a high 11:1 air/fuel ratio wouldn't result in smoke. Your information suggested you performed an oil change 50 miles ago...oil does have a yellow color when new. It's only black once it's seen lots of use.

Are you sure that the turbo you installed is in good shape? If the turbo is leaking oil it would explain why it's making it to your tailpipe and why you're seeing smoke. If the smoke isn't from oil in the turbo there are still a few other options of which none can be fixed with a tune.

In regards to the tune, it would not cause your RX8 to smoke unless the OMP was cranked to it's highest position. Since it still smokes with the stock tune that eliminates the base map as the culprit. It also means that even with an updated calibration you will still have mechanical issues. I'd get that checked out and fixed before anything else is done.

If you had a shop perform the installation and they signed off that everything is fine I'd take it to them and let 'em have at it. There is nothing that can be done via a tune that will fix mechanical problems.

 

my guess would be that the excess fuel has disolved carbon from the exhaust walls ....

 

The turbo was rebuilt and I haven't even put 10 miles on it. As far as the oil being yellow I don't think so because I use Royal Purple and brand new it's a dark dark purple. I have spent too much tim dealing with a shop that it really is my last resort now because of my very busy schedule due to training etc. I want to see if I can save the headache of going to a shop and maybe pinpoint my problem because I have yet to find a reason for yellow substance at the end of a tailpipe... Could it be a fuel additive?

 

so much fail in this thread. only one or two posts have stated the simple, obvious first things to consider the culprit

 

What are your fuel trims, MAF readings at idle?

I think you may have an injector stuck open, wired the fuel injectors wrong or have a massive vacuum leak.

Definitely mechanical issue. THat sludge looks like an *** load of fuel. Pull your spark plugs out, that will tell the tale.

 

Semper fi bro---ex marine here.
agree with Kane-- pull the plugs and more will be revealed.
I have never seen a car run so rich that it made smoke/vapor. usually the ignition system cant hangle that much fluid? heck even with my water meth on there is still no smoke out the pipe. Plus your car is running ok --right--no misfires--no hard starts etc?
The only time i have seen white/gray smoke after the engine has warmed is when a coolant seal was bad. Doesnt take much coolant in the combustion chamber to produce it. Its the antifreeze part of the coolant that does this---not the water part.

after reconsidering I'm leaning towards this as most likely .

Wondering if others that have done this had the smoke issue as well ?

 

at least one person has, I remember reading about it

 

Well if you know then share your knowledge.

 

If I had a bad coolant seal wouldn't my oil be contaminated? It would show up as white/milky. Or somehow with a bad coolant seal the coolant gets to the exhaust but doesn't get to the engine at all to contaminate the oil?

 

Ok, I will start off by first checking if my fuel injectors are wired wrong, I'll look up a thread on how they should be unless someone wants to be so considerate to just tell explain it to me. If, that's ok, I'll check my spark plugs, I know the plugs are good because they really are brand new, what else will I be looking for? Excess fuel when I take out my plugs? I have not had any hard starts or any other problems like misfires.

 

Yes, look for fuel soaked plugs.

 

I have the four yellow injectors and two red. How could they possibly be hooked up wrong? The four yellow are on the passenger side of the engine and the two red on the right. Look at the pictures I posted of the crap building up in my exhaust, could it be nything besides fuel?

 

Points for spelling numbers below 10.
A semicolon after "exhaust" would have been nice. Typo is excused.

 

So, am I approved by the "Grammar ****," or will this be a never ending battle?

 

well if 3 of the most knowledgeable people on the forum could do it - I'm sure whoever fitted your engine could manage it as well .

And it's the plugs that get mixed up , not the actual injectors themselves .

 

Is there a diagram that I can look at too compare it to the way my injectors are wired? And if they are wrong how the hell do I get to them?

 

Google the Mazda RX8 Service Manual, might be able to download it ( I did)

I don't have it on this computer, so I can't help much...sorry. To get to them you are gonna have to take the UIM off...sorry, it sucks I know.

We are assuming that whoever put your engine in started with a bare block and fitted all the components to it - this is when the wireing can get fuxxed up . If the engine was complete (ie never been stripped down to a bare block). Then it is extremely unlikely that it would be wrong from the factory.

And yes you need to take the uim off which is a real PIA the first time you do it . There may be a DIY somewhere on that.....

Before doing that I would pm CRH and see if your symptoms closely match his experience .

 

The engine never went to just the short block, I swapped it with it's stock harness and everything. Who is CRH? He had an injector problem?

 

if you are sure the harness has never been removed then this wont be your problem ....

CRH had the issue , as did Teamrx8 (i think) MadaManiac and Shadycrew

 

Were the symptoms just like the ones I am experiencing?

 

/\ That is what you need to pm them about .
