Rejection Sticker with LMS Tune?

[4DRHTRD]

perhaps LMS could devise a tune that could be used to get the car to pass the test.

You can't tune to make readiness work, sorry it can't happen. Only way is to include better cats.

I wasn't trying to say they could. I understand how readiness works I think. I know the car will have to be returned to stock, and driven and have certain amount of key cycles to achieve readiness. LMS catted DP's don't throw codes immediately I believe when they 1st offer them people didn't start throwing up codes right away.
But it maybe just possible to return to stock and baby the car so it doesn't throw a code long enough to get it to pass.

But if not I'd give these a try before I'd start swapping DP's

The code is what happens after it tries to go through the readiness check and realizes the cat isn't working to 100% efficiency.

I know when I had my speed 3 couple guys figured out which wire to soder a diode into and it would kick the false reading to trick the ecu. Could google that and do a little digging.

I say  , were there is a will there is a way .... A knowledgeable  programmer/ automotive electrical engineer COULD do this .... the average joe  cannot .. its all wrapped up in code .

I did that too on my speed 6 when I did catless downpipe, won't work on these I'm afraid.
Please try though, I could be wrong but the new O2 aren't just a resistance it's an actual feedback loop now from my understanding.

Did some reaserch, maybe this will work:

$150 for 2 (required) so it's cheaper for new purchase to just get downpipes with cats that pass readiness checks.

Man .... I sure am glad I  don't have to deal with emissions testing .

Amen to that brother...and THAT is why there is a set of NON-catted DP's in my very near future  :drive: :ford:

 

[dcpatters]

the O2 foulers are hit or miss.  depends on length, etc.  Worked on my Evo X MR.  But again, not 100%

I'm going to go with replacing the stock dpipes and tune and go for a re-test.

If this has to be an annual thing and if there's any interest, i might as well put the LMS dpipes up for sale and switch over to PPE Cat'd pipes.

Thanks all for the help.  Love living in an emissions friendly state!

If you go that way you won't regret the PPE pipes. I'll attest that the catted version does not throw a code in '13 SHO after almost a week. So it shouldn't in anything it fits. Just to be impartial there is at least rumor that LMS may be going to the same Magnaflow cat to avoid CELs and perhaps EPA sanctions.

Does anyone know if the non catted DP's will fail Illinois emissions standards? Soem guys with Evos were saying that the downpipes they had were non catted and were tuned out o2 sensor and passed emissions if thats the case ill go non catted

Google Illinois emissions and read up for your state

Just says OBD test. So I googled if peopel have passed and it seems soem have by tuning out their o2 sensor as they do a readiness check. No visual ect. I just wanna make sure before I make a purchase on something.

How is the OBD test performed?

The OBD test consists of connecting a scan tool to a vehicle's on-board computer to determine the OBD system status (readiness checks), to determine whether the Malfunction Indicator Light (MIL) is commanded to be illuminated, and to retrieve any stored diagnostic trouble codes.

Vehicles will pass the OBD test if the OBD system is working, all required emissions system readiness checks have been completed, and the MIL is not commanded to be illuminated.

Vehicles will fail the OBD test if the MIL is commanded to be illuminated and diagnostic codes are present. Vehicles will also fail if the OBD system is inoperable or if the OBD connector is missing, damaged, or inaccessible.

You will fail if you don't have emissions readiness checks passing.

So if the o2 sensor is tunes out it essentially will be non existent to the test and the overall test will pass as ready?

No you will fail readiness, it checks for the rear O2's and makes sure they are there. If they are tuned out they never come ready.

 

[IHeartGroceries]

If you use a tuner or other similar method, and the device is able to disable MIL codes, it is simply removing the trigger to illuminate the MIL. But, as stated, you'll still have a not ready present for emissions testers.

I learned that the hard way.

No emissions in Florida, but the stage 1 flash for my VW would throw CEL without O2 sensor spacer on catless downpipe. Stage 2 deletes second O2 sensor and car always passes readiness when I scan it.

Sorry - a little foggy on all this, but my question is - are all my 02s on and functioning?

The last tune I installed from LMS was for Meth, then I installed PPE downpipes w/cats. I called LMS and asked if I need a new tune for D/P's and they said if I'm not throwing codes I'm good to go

If you installed PPE downpipes with cats you shouldn't be throwing a code. Does your tune have the rear O2 turned off, no idea but you can go to any Checker/Auto Zone, they have scan tools and have them check if all your readiness checks are passed.

As info: readiness can be achieved on the 13 SHO with 20 minutes spent at highway speed, 15 minutes stop and go with 3 or more periods of 30 seconds plus at idle.

I went through this several times trying to get through TN emissions testing. I may have the highway and stop and go time flip flopped. I did all my idle times in "P" for park and went at least 2 minutes each time.

I did return to stock before I did the drive cycle and passed emissions but immediately following went back to the Livernois tune and have not thrown any codes since. I has been several months now.

I learned that after clearing the codes then performing the drive cycle they will come back in if nothing was done to correct the issue.
