Does changing the OE TB and injectors affect the emissions enough to make it fail? My State requires annual testing for registration.
Thanks.

It depends on the condition of the engine before hand. With that said I have had my Jeep SMOG'ed with the 4.0L TB as well as Design I and Design II #19 injectors and passed easily.

Good cat and a fairly new oxygen sensor does wonders for the emissions on a good running engine

MIne just went through with flying colors.

Built engine with cam still did fine...

Do they dyno test up there? Are you running a aftermarket computer?

Thanks for the input. I should be okay then.

up where? - did you mean Canada? if yes, here in British Columbia requires an "Air Care" test, which basically consists in an idle test and a run test - there is a dyno like device (not a HP dyno though EDIT: they do call it a dyno though, this is from their description on the site I listed below: "1992 and newer vehicles except diesels are tested using the most advanced dynamometer test currently in use anywhere") which basically simulates the city/highway driving - takes the vehicle from a full stop to 90kph (55mph), holds the speed at couple of levels i think and measures all emissions during the test. When completed you get a printout with your results, there is a max value for all readings which you have to be under or you cannot insure the vehicle. There is a spending limit though, so depending on year you can spend a certain amount at a certified shop and they will insure the vehicle based on that, the idea is that either spending the money will make the vehicle better or at some point is not worth it to do it again and will be ridden off. the testing is required every 2 years for newer vehicles (my 95 YJ falls in that category) or every year for older ones (my 86 Camaro is in that category) - also for the older cars like the 86 camaro the test is less extensive, i think it's just idle and from full stop to 30mph (takes about 3 to 4 min compared to the '95 Jeep which is about 10 min)
i passed "air care" twice with a cone filter, 4.0L t/b and helix spacer
Just looked at the site www.aircare.ca
here's the detailed info from there:
Inspection Info - Description of the TestsOn-Board Diagnostic (OBD) Test
Eligible 1998 and newer light-duty vehicles receive a scan of the vehicle's built-in OBD monitoring system to ensure there are no defects with any of the vehicle's emissions control systems.
Read more about the OBD test procedure.
Watch a video describing the OBD test procedure.
IM240
1992 and newer vehicles (except diesels) are tested using the most advanced dynamometer test currently in use anywhere. The test measures emission levels for HC, CO, and NOx while the vehicle is driven over a pre-defined series of accelerations, decelerations, and cruise conditions. The test may last up to 240 seconds depending on how "clean" the vehicle is in the early part of the test.

Watch a video describing the IM240 test procedure.
D147
Diesel vehicles (other than 1998 and newer light-duty vehicles) are tested using the D147 transient opacity test. This test measures smoke opacity levels while the vehicle is driven over a pre-defined series of accelerations, decelerations, and cruise conditions. The test may last up to 147 seconds depending on how "clean" the vehicle is in the early part of the test.

Watch a video describing the D147 test procedure.
ASM / Idle
1991 and older vehicles (except diesels) are tested using a steady-state dynamometer test, but still uses a dynamometer to facilitate emissions measurement while driving. The test measures emission levels for HC, CO, and NOx while the vehicle is driven at a steady speed of 40 kph and again while the engine idles. The driving test may last up to 90 seconds depending on how "clean" the vehicle is in the early part of the test.
Read more about the ASM/Idle test procedure.
Watch a video describing the ASM/Idle test procedure.
Gas Cap Pressure Test
Most vehicles also receive a functional inspection of the gas cap to ensure that it does not allow fuel vapours to escape to the atmosphere.
Tampering Inspections
Most vehicles are also visually inspected to ensure that the most important emission control devices have not been tampered with.

That's with my stock computer and all the engine mods intact.
Oregon removed all the dynomometers. We just have a idle speed sniff test again. :clap:
Or they plug into the OBDII port if you have it...
I'm still chasing gremlins with the stand alone, I need a dead ECU to
get a good connector off of, I want to be able to use the stock harness
and not have to swap the engine bay harness when I want to play with
the aftermarket ECU. I just sold my Haltec Tec 3 and am going to buy an SDS.
The Haltec was too over the top fiddly for my needs.
