Hi,
This is my first post so I'll try to keep it brief. Sure.
Virginia has local, private service center Emissions testing. Although Va. prefers the 2 speed roller test, it does allow a 2 speed idle test if the local tester deems it appropriate. The roller test checks HC, CO & NO. The idle test checks only HC & CO. My local tech has always done the idle test as the car shifts really hard and wants to "jump" on the rollers. This last time we both forgot and did the roller test. As the Champion heads EGR passages are filled, the car failed the NO portion of the test miserably.
Heres my questions:
1. Are there any tuning tricks I can do in terms of Emissions chips, fuel pressure, etc, to try to get the car to pass on NO? The car does have an ATR cat. thats about 9 years old. According to the folk at ATR it should be a 3-way, but maybe its just worn out. No problem getting a new one if it might help.
2. Does anyone know how long failed emissions tests stay in the VA system. VA does allow a free retest within 2 weeks of the failed one, but if the info has since been purged, my tech could redo the test as a 2-speed idle test, hopefully passing with flying colors.
The failed test was back at the end of October. One day before the Tags died. Since then I've been warming the car up in the driveway at least once a week and occasionally sneaking the car out early Sunday mornings around the neighborhood just to keep everything up to snuff.
Heres the test results:
HC ppm: Limit 118, Me 29
CO: Limit 0.66, Me 0.00
NO ppm: Limit 905, Me 2312
15MPH
HCppm: Limit 114, Me 46
CO: Limit 0.70, Me 0.00
NO ppm: Limit 824, Me 2241
25mph
Sorry this post got so long. I don't do this very much..
Thanks for your time and hope to hear some advice soon. I miss my Baby very much!
