FX45 Emissions

Discussion in 'FX (03-08) - Engine & Drivetrain' started by TurboMack, Aug 13, 2007.

  1. I have seen all the additions on the guys cars in there signatures. As far as adding exhaust, CAI, +2, and re-flashing, do any of these upgrades hurt or help when it comes to emissions testing? The reason I ask, I race a Buick Grand National with several upgrades and when its time for emissions testing every two years I have to change a few things on the car. Whats up with emissions on these cars with some upgrades????

    Unless you remove the CATS or change out to test pipes I don't think you will need to worry about the after market exhausts. A CAI, +2 and TS reflash will not fail emissions testing. I have not heard of anyone with emissions problems with any of these mods. As far as turbos, sc'rs, CATS and test pipes, as you are probably aware there are avenues to get around this ;).

    You will not pass with test pipes, messing with the cat is a no-no. Swap them and put them back on after.

    You can do as some people(^^^^^) :pdo "pay to pass" ;), if you can find one in your area, which I don't think it should be hard.

    You wont pass with the test pipes - for sure. You wont pass with the CAI either (if you have one) Cuz of the visual inspection.

    Heard about this - but finally got more details about it tonight. Not sure if this is worse or not. I went this morning, but the place I goto was closed.

    AB 2289 - OBDII testing only - No more tail pipe sniffer starting 1/1/2013 in CA

    Chaptered Bill text link :
    AB 2289 Assembly Bill - CHAPTERED

    Set to begin January 01, 2013; Model year 2000 and newer vehicles will no longer require the tailpipe emissions test portion of the smog check process. AB 2289 will require late model vehicles be administered the smog check's visual and functional tests only.

    The implementation of AB 2289 is expected to reduce the time and cost of the smog check. The program will now take better advantage of a vehicle's OBD II technology by eliminating tailpipe testing and instead using the vehicle's own OBD II emissions monitoring system.

    This new smog test system is already in place in 22 other states. "This new and improved program will have the same result as taking 800,000 old cars off the road, also resulting in a more cost effective program for California motorists." said ARB Chairman,
    Mary D. Nichols.

    Currently California's smog check procedure requires all vehicles undergo a tailpipe emissions inspection to measure harmful pollutant output from the tailpipe, a visual inspection for present and properly installed emissions components, a functional test to insure the proper operation of various emission components; and as part of the functional test, an OBD II computer diagnostic check.

    Under AB 2289, the tailpipe emissions portion of the smog inspection will be eliminated for 2000 model and newer cars, trucks, vans, and SUVs.
    Background on the OBD II system - All vehicles imported into the United States as of 1996 have had to be equipped with an On Board Diagnostics system referred to as OBD II. The OBD II diagnostic system is designed to monitor all aspects of your engine's emission conditions and report this information to a central database within it's computer. This information is processed and checked against the computers pre-determined values for various input levels and performance patterns.

    If any problems are found, the computer will determine whether to alert the driver or not. If a decision has been made to alert the driver of an emissions problem, the "Check Engine" or "Engine Malfunction" light will illuminate on the vehicle's dashboard. In more serious emission conditions the computer may even begin to rapidly flash the "Check Engine/Malfunction" light indicating to the driver, that the vehicle needs immediate diagnosis/repair attention.
    AB 2289 now requires the smog test inspection to rely on data from a vehicle's own on board emissions computer to determine the vehicle's harmful emissions production as opposed to using a smog machine to sample the vehicle's emissions output from the tailpipe. This design is expected to reduce the cost of equipment at the smog station, reduce the amount of time it takes to smog check a vehicle, and reduce the cost of the smog inspection to the consumer.
