[s-cars] Looking for emmissions outputs and some help

[Brian DeWyngaert Jr]

All I am curious to know what other UrS4s are getting on their emissions.
1.I am looking for in particular your amount of HC in ppm and your % of CO.
2.Please list which engine speed these numbers came from, idle or 2500.
3.If you could please advise if your ECU is stock or rechipped (and if
so who chipped it).

I ask because after a bit of frustration and 8 months now of replacing
parts that had gone south, I am still failing my emissions here in VA,
but only for the idle test. My results have been sitting at 186ppm for
about 4months now and they need to be below 125ppm @ idle.  When run @
2500rpm my ppm is ~ 68ppm and the legal limit is 125ppm.  My CO is
.10% for both tests.  I have run out of ideas on what could be wrong,
and the audi tech at HBL is still scratching his head.  So I am
turning to the collective brain of the list to see if some answer
might be scratched together.  The only real mods to the engine (that I
am aware of)  are ECS stage 1 ECU flash, a Forge DV valve, and the
adjustable wastegate mod (although I have never played with its
settings, this was done by the previous owner).  One other thing to
note the dilutions determined by a 4 gas analyzer were as follows: @
idle. 14.1 @ 2500rpm 14.7
I am open to all thoughts on this, I am in the process of delving
through the archives on this list to see if something similar has come
up before.
The 2 thoughts I have,
1. did the previous owner do something to the precats or cat itself?
2. is it possible that this is a by-product of the ECS tune?
