[COLOR=Navy]So I have had my 2004 SE3P (RX8) for about 2 years and I'm going to upgrade the car. I think the mazsport turbo 2 kit would be right for me, as I would be happy with 300+ at the tire.

 

1. code reader/diagnostics tool/scanner
2. yes, the CEL does illuminate even with a cat in (car's running richer than it thinks it should)

 

I know there are a few running the new turbo's out there, what are they doing to get around these perils?

 

I don't have a CEL from the missing cat (Running the greddy turbo + interceptor-x)

The mazsport kits all come with the int-x, and you will get two CELs from your car detecting the system running rich. There is no work around at this point in time, but Scott has said he's working on a fix.

Just buy something like the scangauge2 and use it to read the CEL and reset them. That way you can at least keep an eye on the CELs being displayed (in case one of them turns out to be a REAL problem)

 

Wait a minute, this is really confusing me... how come you arent getting a CEL with both the Turbo and No cat? Is there something that you are doing that I cant copy? I dont see the difference from a CEL point of view if you are running the Greddy Kit or the Mazsport Kit. If I bought the scangauge2 and used that wouldnt the CEL's come back on once they went off because the "problems" still exist (no cat, and turbo installed) Have you had your car tested for emissions? If so, how did it go?

 

He is getting the check engine light. Everyone does, unless they are using the magic dongle.

 

And he lives in FL,
Here we just don't give a ****

 

Yes, no emissions testing here in FL.

The CEL would come back, but the scangauge2 would allow you to keep resetting them and or viewing what CELs are popping up, allowing you to know if there is a serious CEL or just the random "Your system is too rich" ones.

 

Ok, back to my original question though... So I can temporarily solve the problem of "not having a cat" during the emission test simply by reinstalling the cat for the duration of the test, now - what about the Turbo? (Besides take it off for the test) - If I really had to live with driviing around town with a CEL, I could live with it (even know I dont want too have to). Taking the turbo kit out for the test would be a real P.I.T.A though, dont you all agree?

 

Emissions is a major PITA with a turbo. My solution was to put the stock injectors back in, take out the IntX, tie open the wastegate, and put in enough drive cycles in this 'stock' configuration so that the PCM was happy. The car drives like **** with that gigantic exhaust restriction, but you don't have to take the turbo kit off. Then, get the sticker and put the car back into ***-kicking mode. The EPA regs will not allow a chassis that was built with ODB-II get a sniffer test. It HAS to pass the plug-in test - meaning no codes and enough drive cycles so that all systems checks are available.

Also, for all you 20b lovers, the EPA also states that it is illegal to put an engine in a chassis that is older that the chassis - regardless of engine type. So, if you are contemplating an engine swap of any kind, you should keep that in mind. Your car will be illegal after the swap - even if there are no CELs and you have a cat. The only legal engine for an RX-8 is a Renesis. (techincally, only one produced in your chassis's year of production, or newer) What really bugs me is that you can't get a sniffer test either. Despite the goal of the regs being to reduce hydrocarbons, you can't ever pass the test by measuring hydrocarbons if your chassis came with OBD-II from the factory. Its total bullshit.

 

Maddog, thanks for the information: I found it useful. Any reason why you have to take out the int-x? Cant you just use a different program/map? My guess was if I somehow opened the wastegate fully it would work, but I didnt want to post this and sound stupid if I was wrong. Please lets keep this thread alive and see if others have useful answers to this question.

 

The short answer is that the PCM will always throw a code with the INT-X installed. you must take it out until someone comes-up with a fix.

 

"Magic Dongle"?

 

the EMU that ships with the upgraded greddy kit and the upgrade kits has a dongle that prevented CELs from appearing for system too rich.

 

So, should I be able to get this "magic dongle" and use this with the INTX/MAZSPORT kit it will work too? Putting the CAT back on in combination with this should get me to pass emissions with no CEL. The thing that makes me wonder is what physically is different about that "magic dongle". Thanks mysql101 for your feedback!

 

Okay already. Enough spoon feeding. You can find all the information you need by searching the other threads these topics.

 

I don't know if the magic dongle has been proven to work yet.

 

I used it for 2 months without getting a CEL regarding system too rich.

Well, I did get a CEL about twice about the intake manifold, but it had a plate blocking it... so that was expected to some degree.

The greddy dongle doesn't work on the int-x, or we'd all have it on our cars. Scott said he's working on a fix.

 

Yes: I agree it looks like your CELs came from unrelated changes, why were you blocking it with a plate? So you have had the kit for 2 months?...or you took it off? Please elaborate.

 

i had the emanage ultimate. no cels. removed it and went with the int-x. two cels.

ultimate upgrade kit ships with an blocking plate. so it doesn't have to deal with the 6 ports opening up.

 

I wonder what kind of fix Scott from mazsport can come up with. My guess is that if this fix removes the CEL from coming on with the new injectors (too rich) all I will need to do is put on a CAT to pass emissions. This would be the perfect scenario.

 

Indeed it would, which is exactly what Scott's been talking about doing. More specifically, one of our club members is working on adapting the Greddy dongle to work with the Int-x

 

Sounds exciting, Maybe I wont have to sell the 8 and buy a 7, it depends on how long it takes for them to come out with the fix. If I can find a buyer for the 8, then I'll buy a 7. If not then Ill boost it.

 

this is promising news for myself - I'm looking to go with a Type 3 kit within 6 months however my inspection is coming up in 9/07 of this year. With all the money I would be spending in parts and labor to make a 400HP RX8 - I must be able to slink by emissions somehow, if scott is working on a fix to get no CEL's with his Kits+IntX then all will be good in the world

 

Same thing here. 47 bux in NYC to do emission test, CEL = instant Fail.

So its good news, way to go scott !
