Good numbers.
SickFinga I suggest you get a custom tune. Your AFRs aren't that bad, but they could use some fine tuning.
As for the other car, it's running a bit lean if it's a forced induction car. Some bad gas on a hot summer day and he can say goodbye to his rings/pistons. I hope the timing is somewhat conservative
BTW what's Furious' setup? I remember SickFinga had a supercharged 328(?)

Furious has 325i with 3.0l swap and AA Supercharger (8.5psi)
I got M3(3.2l) with RMS Stage II SC (11psi)

Oh ok. Is there any place locally that can dyno tune your ECU? If so you should invest in some good tuning. If my AFRs looked like that I wouldn't rest till they were perfect. I guess that's why I have standalone and a wideband hooked up 24/7

Emailed RMS with dyno graphs, I'll see what they'll say
Standalone is way over my head

Hopefully they can burn you another chip, I know a few VW companies burn/re-burn chips based on Dyno charts/AFRs.
Standalone is fun to play with but it's $$$$ and can be a bitch on a car that is driven on a daily basis

Nah, car still runs the same, sputtering at 4k rpms and check engine is on.

We did it at Dyno Power Services

Did you measure the a/f ratio at the tailpipe or the bung that was installed last year? If it the tailpipe, the cat has an effect plus there is a delay in the reading. Also, what type of O2 sensor was used? Was it a wideband sensor like I use or the type used by emisions testing places where the exhuast is sampled by a hose?

I finally have time to look at the tuning I read from your car, I'll have a look to see if I can lean it out.

Mark, it was at the tailpipe, I dont think I have that bung anymore since I installed longer headers and my cats were cut.
I'm sure it was wideband, since that place only does dyno tuning.

My O2 sensor is a zirconia O2 sensor which is placed in the tailpipe.

The other type of ( electrochemical sensor ) is also a wideband sensor but a sampling tube sucks up some exhaust and then brings it into contact with the sensor about 15 feet from the tailpipe, introducing a delay. I assume they have the zirconia type then but wanted to be sure.

Here is some info on the two types:

Vlad,

I am going to make a new file for you car based on these graphs. Is the CEL always on or only in certain rpm ranges?

Give me a call today if you can.

Thanks Rocco.
Headers? Rocco I didnt feel any difference between 200rwhp and 340rwhp, do you really think I noticed any difference with the header?
