[s-cars] High CO

[Mtgadbois at aol.com]

Craig,
 
I'm near Chicago and have a similar setup, 95.5 S6, and at testing 107K  
miles, RS2 turbo and exhaust with Minhea recommended injectors and his generic  
RS2 software.  My last pollution test was;" HC Limit 220 - my reading 8, CO  
limit 1.2% - my reading 0.0%, CO2 Limit n/a - mine 14.6%."  I did not do  
anything special.  I think I changed the plugs and air filter at 101K miles  and I 
did not drive the car on high speeds before the testing.  I do not  know how 
this information helps you but I would rule out Mihnea's tuning as  being a 
problem.  BTW, I get about 19 mpg in all around driving.  I  get 30+ in my Boxster 
at >75mph (only did this once in 9 years and 62K  miles).
 
Hey Baloney when do you want to do lower Wacker at Hap scaring  speeds?
 
Regards,

Now with 127K miles and I don't care what my car is worth - It's not  perfect 
and it's not for sale.
 
BTW 2001 Grginch Zinfandel, Napa Valley - Dominicks $32. is great.   ENJOY.

Gentlemen,

Been meaning to throw this one  out to the list brains for awhile, 
thought I'd better before half of our  collective brainpower gets 
mired in //S-fest.......

My car has  flunked the sniff test at our clean air police in WA state 
twice now. Nearly  5% on the CO (1% max allowed), and just barely 
passing HC (180/220). These  are cruise (2500rpm) results. Idle 
passes. A little history: MRC chip, RS2  Turbo/Mani, Lucas 37# 
injectors. After tuning (1.5 tears ago), my car always  ran rich, so 
much that I would get soot on the bumper after two tanks of  gas. MRC 
provided a leaner chip - still had soot, and poor MPG (16  combined).

A new 1.8T coil pack cured a high boost miss, and alot of the  soot. I 
can still get the motor to ping during WOT however, and performance  
is noticeably variable depending on outside temps. MPG unchanged.

I  also now have a 1.5 year old Wahler thermostat going, as my temp 
gage barely  ekes out of the cold zone. However, sitting in wait for 
the sniff monkeys,  the temp did elevate to slightly hot, and I did 
flog the car mightily just  prior to the second test. Also, for the 
second test, fresh Mobil 1 was in  the sump.

Thoughts? Think the kittys are clogged from running rich? And  what is 
it with Audi thermostats??? That is one thing the 'Murcans can do  
right...and A/C.....

Any input appreciated - soon - as the next  couple weeks of bandwidth 
will be //S-fest oriented, and rightfully so. I  would love to go, and 
look forward to reading about this years  tomfoolery.

Regards,
