    Is it necessary to take out the dp fix and just leave it there?

    Why every year though? Emissions testing is once every 2 years here in Illinois. Is NY State different?

    If they pop the DME box with the JB4 in there you'll have some explaining to do.
    Dealer opened mine with just the USB cable serial end I left in there, and nobody asked any questions as to how that got there.
    They were wondering how I knew how to open the DME box though. Teech came with a screwdriver and started prying at the plastic brackets...
    I just jumped in and clicked 4x and voila, DME housing cover.
    There are two theories to arguing with women. Neither one works

    I really hope with this open source stuff, you can just have all your emissions monitors always set to "ready" and no catalyst codes. That would save alot of hassle.

    NY state inspections have to be renewed every 12 months.

    Man, I really don't think that's right. The post cat sensor is for O2 emissions purposes only. The engine uses the pre-cat sensor for all its calculations.

    At least that's what I've always been led to believe. I've had the dpfix on my car for over a year now. Would really like to know if this isn't advised.

    Terry?

    I've done logs in both banks with the dp fix in and my lambda afr would be only at most a couple tenths off from each other or spot on. I'm leaving mine in for now unless there is more proof that the dp fix screws with your afrs.

    We offically don't suggest it for long term use as it blends the two rear banks in to one, and that can cause trims to go out of whack over time. I know many have run them for 50k miles without issue. So your mileage may vary. But our official suggestion is to remove it when you leave the race track. Click here to enlarge

    i ran a dpfix for over a year, and when i took it out and re-set adaptations i did notice my a/f ratio's were slightly more rich. not sure if it was making the ratio's lean out over time or not, just worth noting

    Thanks for the feedback. I don't mind removing and reinstalling a couple times a year. Will my car run right w/o the dpfix and no cats w/o a tune? I am FBO but don't have a tune on the car.

    So if a car is FBO w/o tune will the AFRs be ok with the post cats reading very rich (or whatever the term is)

    Also, have you ever seen anyone have any luck with gapping the post cat sensors? Or would this mess up the trims over time too?

    Thanks for the info!
