Emissions tests don’t work the way you think they work. That’s like step one of an emissions test is to make sure the bulbs comes on with the key forward and goes out after you start the engine...

This. Automatic fail, at least in California.

For a non-OBD 2 car like the FD, though, a clever person could whip up a small circuit timer that would send a 12v output for, say, 5 seconds when powered by the ignition and then turn off. Something like this wired up to the check engine light circuit would solve this kind of problem.

Or just get a 1995 Federal ECM.

Sure, if you're handy with a soldering iron you can build a simple 555 timer circuit, which consists of an inexpensive 8-pin IC (https://www.jameco.com/webapp/wcs/st...atalogId=10001), a resistor and a capacitor. Or you can buy a ready made timer circuit (
Amazon Amazon
).

I just got a federal 95 ecu . Didnt want to deal with anything extra
5minute swap easy peezy

thanks guys for all the suggestion. It have benefited me in the regards of emission testing and will most likely help others aswell

Thumbs up Emissions Testing Update for 2018

Here are my latest CA smog test results for our '94 FD. This is the first test with the new engine (1 K miles on engine, 114K on car). Compare with previous test(s) in my previous post #21.

^ have you replaced your O2 sensor recently? Your CO % is higher than average and your NOx is consistently lower than average between your two emission tests. This can indicate a degraded o2 sensor. On an OBD II car you would throw a code. Since it is biased toward higher CO%, that indicates you could be running richer than necessary in closed loop cruising, costing you highway gas mileage.

An astute observation, arghx. I'll look into that. Thanks!
