I'm thinking of registering my 914 in Colorado, cars been running better than I ever remember, but I failed my e-check today. Visual inspection was fine, needless to say they couldn't fine anything on the car, but that also means they didn't see I have no smog pump or catalytic converter. I even passed on CO2.
But my HCs were 1825 at 2500rpms and 1047 at idle, 600 is the limit.
And my COs were 11.7 at 2500rpms and 8.19 at idle, 3.5 is the limit.
About the car. It's a 2056 running D-jet. I turned up the fuel pressure to compensate for the extra displacement, but I think that's how I shot myself in the foot. I'm also using SirAndy's old MPS. It's a 1.7 that he tweeked to run his old 1.8. My car loves it though. My car ran like shit with the 2L MPS, and it held vacuum and everything.
I think that covers it. I'm thinking of turning down the Fuel pressure, leaning out the idle on the ECU and crossing my fingers. Any other ideas? Do those numbers seem way to far off to be cause by fuel pressure?
Thanks guys.

Colorado isn't quite as anal as CA... yet. They don't check timing here. They only check the CO and HC with a tail pipe sniff test (standing, no dyno). They don't even do as thorough an inspection for smog equipment as they do in CA. They're supposed to though, so beware.

And generally speaking, retarded a few degrees will help a little in an idle sniff test, but stock should be more than adequate.

It's not exactly *good* news, but Colorado has a cap on how much you are required to pay in attempting to meet emissions requirements. After that, you can get a waiver:

The limit is $75 for 1967 and older vehicles and $715 for 1968 and newer vehicles. Cost limits apply to all vehicles regardless of whether they failed the idle test or the I/M 240 test. However, these limits do not apply if the vehicle failed for visible smoke or missing emissions control equipment. You may be eligible for a waiver if you have reached the spending limit and your vehicle still won't pass the emissions test. Hardship waivers are also available. Call the Division of Motor Vehicles Emissions Office, 303-205-5603, to inquire about waivers.
