I am having a hell of a time getting a customer Shelby GT500 to pass New York state inspection. No matter what I try the vehicle will not run the OBD-II readiness monitors. I guess it isn't as easy to set like GM vehicles. The vehicle has a Steeda CAI, Steeda UD pulley, Long tube headers and high flow cats that will not pass the P0420 & P0430 efficiency like the (4) stock cats that came stock on this vehicle. I have attached the tune if someone can lend some advice.

Tunes not there.. Eric was supposed to be adding some tables that should allow you to solve this issue. Post the tune and Im sure one of us can help you out.
I added the Cat Monitor Failure Ratio parameters to the GT500s this morning. Update and it should be there. I will get it in everything else when I get the chance.Originally Posted by Fire67

Sorry forgot about the tune
I was also getting P0133 & P0153. I assume from the long tube headers. Correct way to adjust this?

Okay just updated and I now have Catalyst Test, Failure Ratio for B1 & B2, that range from 0.0 - 2.0:1
OEM file they are set at 0.710:1 and 0.660:1
Could someone explain these values and what they mean. Is 0.0 or 2.0 a disable?

I am looking to increase the delay time or response time of the primary O2 sensors to do away with the P0133 & P0153 codes. Also common value or industry standard to use with long tube headers and high flow cats

A value of one should eliminate it.

On long tubes, increase the O2 Transport delay and heater duty cycle. 25% is a good value to use on the delay. Once our 2.25 scanner is done, you will be able to log the learned transport delay and just put that back into the tune.

I just updated and still don't have the Catalyst Test, Failure Ratio for B1 & B2 under engine diag. I have it for a 2008 GT500 that I am working on but not the 2011 GT500 and 2012 GT500 that I need really bad.
Thank You
Post the OSID you need it in. I will add it today. At some point I will have it in everything, right now I am adding it by request.

Eric, I need it in the following two operating systems 2012 GT500 FGDH3S3 and 2011 GT500 FGDX2S6.
Thanks Again

Eric, I was just wondering if you had time to add the Cat Monitor Failure Ratio parameters to the osids that I posted for you yesterday.
Thanks Again
This is a little different on the 2011+ cars. I'll work on adding the parameters now.

OK, parameters added into a few of the Copperhead definitions, including those that asked for it above.
You will want to raise all these values to the max. ;-)

Eric, I didn't know what the max value could be so I set all of the above values to 1. Before I made any changes the car would randomly pass or fail the cat monitor test. The max value allowed during testing was .885 I believe and minimal was .1something. The vehicle would test in the .850 to .920 range and either pass or fail if the .885 threshold was met. With all the values set to 1 the car failed the test with a .910 and the min and max threshold values are zero. That works great for the minimal threshold but what do I do to raise the max threshold. Also the O2 monitor and O2 Heater monitors won't run, I raised the O2 heater up 25% as you stated. Any info on what the four charts above due. The old 08 GT500 style was very simple with 1 chart and a high low threshold.
Once Again,
Thank You
interested to know this as well

I'm having a similar issue on a 2005 GT, is there any way to have the cat monitor parameters added to OSID FBJR3G5?
Done, it will be in tomorrows build of 2.25

Can you add these parameters to this 2009 F150 OS please?
One was read using 2.24 the other was a ECM and TCM read using 2.25. It was submitted to support to add the trans definition.
Thanks!
