The easier and more reliable way to test the VAFM (Vane Air Flow Meter) is to test the output voltage at the Vs input on the ECU harness. With the ignition "ON" but the engine off you should see a scale from ~.5v to ~4.8v as the vane is slowly opened from full closed to full open (or the other way around... :P ). Then test the temp sensor's resistance as specified in the manual.

The VAFM is a wear component unlike the GTE's KVAFM. There's a rheostat inside and the wiper and pad wear out over time as they're constantly moving. Watch for significant "flat spots" where the voltage changes less with the movement of the vane than it does elsewhere... These generally occur where the vane is less than 40% open as this is where the vane spends most of its time during normal operation.

Have you checked the ignition timing yet? Running great doesn't mean it's running optimally for peak performance or emissions compliance. Increasing the base timing a few degrees will have more effect than adding an octane booster (complete waste of money and if overdone can make your test results worse). Just don't go too far with the timing... As you increase the spark advance the NOx will increase while the others drop a bit. If you go too far though you may cause a significant amount of ping which will cause the ECU to retard timing and add a lot more fuel.

oh wow, thank you cre. i had no idea.

well i finally checked the ignition timing, i borrowed a gun from my neighbor. i was at 7!!!! i moved it to 11, seeings how the cyngus manual said i should be at 10. the car is running so amazing. i think im ready for a retest

this might be a off topic question but since we are on smog tests. here in florida there are no emmisions test, i know cali is anal about them. i heard from some where that if your car is 20 years or older you dont have to obay emmisions or safety standars since its a classic ( i belive the gov said " if your willing to drive a 20 year old death trap be our gusests" not that a mk3 is a death trap) is this the case for the entire US or just in florida?

Actually, there is no federal limit on TESTING for emissions. You may not under any circumstances circumvent or remove any original Fed or Cali required emissions equipment. States may offer an exemption from TESTING based on their own criteria; HOWEVER, most states froze the year before which a vehicle must have been made a very long time ago. In Colorado, for example, the year was frozen at 1974 or 1975 well after the fact and NO, you are not grandfathered into it. I actually have yet to find a state where they're still letting the counter run for "classic" vehicle status (formerly a designation for any vehicle once it's reached 20 or 25 years of age). For 99% of the US this is complete bullshit... and I don't know where the 1% is. Is your state doesn't require active emissions testing you are still accountable for obeying federal regulations and making sure the entire, original or newer emissions control system(s) is present and in tact... You can still get pulled over and ticketed. A "classic" status is not the blanket legal exemption so many people wish it to be.

And before someone brings it up, no, there is no 25 year law about importing cars either.

I know Nevada still is

Joefishizzle · 04-02-2012, 04:10 AM

anyways though. im gonna go for a retest tomorrow guys. im gonna make sure the car is nice and warm by the time its time for my test. wish me luck!

YUP... BUT, you can't drive the car more than 5,000 miles in a year (and yes, they check... well, not always but you never know).

Thanks for clearing that up. I was always curiouse to see if that was true and now I know it's not. I always assumed that if you had the blue classic plate you where exempt because here in my state at the Edison home all there classics don't have cats or any emissions control And there driving around. Well at least I can travle around the states knowing I would have to put my cats back, ( or my fake out cat ) to avoid a ticket. Thanks Cre

Joefishizzle · 04-06-2012, 05:02 PM

okay so i leaned the car to about 11 as mentioned. took the car back, failed again, however i passed 15mph test and barelly failed the 25mph. so i leaned out to about 13 since my NOx was still low. smogged it this morning and the check engine light came on, and my CO and HC jumped back up to were they were. i got check engine 21 and 51.

i think the O2 is an old code cause the new sensor was just put on, so 51....now i measured resistance and my values are way off according to cyngus manual. any help?
