I haven't had much free time lately but promised I would post in this thread for future reference of Evo 9 owners in Colorado. Normally Colorado will run cars on an AWD dyno but they will give you the option to have them scan your OBD system because the factory rims are "low profile" and can be damaged on the rollers.
I am running 88590715 Tephra V7 rom. I never had an issue with them passing my car with all of the settings on "forced pass". This latest go around I failed and was handed a report saying there was an issue with the obd systems being "not supported".
The resolution was changing the "Non-continuous monitor availability patch part 1" from forced pass (e000) to stock settings (4019). Double checking on my generic OBDII scanner, this produced the correct items reading as supported and the items being not relevant to the car reading as not supported.
It was also suggested that I change all of the items on the monitor pass/fail table to match the items on the monitor available/not available table. When I did this my scanner would come up with conflicting info that I was worried about the emission center catching. Example would be: heated cat would read not supported, not available and not complete with the two tables matching. (I was thinking it would be odd if a not available item read not complete.)
When I would change the pass/fail table to pass (1) for everything that same example for heated cat would read: not supported, not available and complete or n/a on my scanner. (It made more sense if it read n/a since the heated cat is indeed not applicable.)
When I compared the readings I would get for supported and not supported items on my wife's stock car, those settings matched exactly.
Attached is a screen shot of my settings that I passed with since its kind of confusing to describe.
I've documented this before. I'm not sure why people haven't adopted to it yet.
I wish I would have revisited this thread before going in for test! I had the original patch settings and failed because of the 3 monitors that shouldn't be enabled on an Evo.
Here's stock vs what works for me:
The "Part 1" value was put back to stock (0x4019).
The "Availability" values are now identical to stock 88590015 ROM.
Pass/fail values were taken from the stock ROM, and then I changed EGR and Catalyst '1'
Thank you for this post
Can anyone from ny confirm these settings work? I am going to assume it is the same test etc. so it should
Sorry to bring a thread back from the dead! -- I noticed the video link in the initial post is broken, does anyone have an updated video and/or instructions on how to do this? Thanks.
could someone pm the videos, i got the tables to show up in ecuflash, but i dont know what to do with the "non-continuos monitor" settings

read my posts, the mistake that all of the Noobs are making on the evo 9 is turning on all of the monitors (even ones that Evo's don't have)
After Step 1: setting the available monitors and Pass/No Pass + non-continuous monitors 1;2;3....
Do I still need to Enable or do anything with " REAR o2 PATCH " ?? or will Step 1 work for both front and rear o2 sensors?
Hmm... I do not think it will matter which o2 settings you have, as long as the force pass portion is right. When I picked my car up from my tuner, I think they applied the rear o2 patch (maybe incorrectly) on my car (years ago). I just did the force pass test (as you see) and everything has been A-OK since.
I am not the most knowledgeable person here with this, but I always do my best to help because I understand how frustrating it can be getting started with this stuff.
The rear 02 patch keeps you from throwing a CEL if you remove your rear 02 sensor. If you throw a CEL you will fail smog.
See... when my car was tuned with tephra I couldn't set the readyness monitor for o2 sensors for some reason. It never showed ready. I thought that had something to do with it. I fixed it with the force pass though. I had a functional O2 working with the spacer trick.
I had the same issue with my rear O2. Was operating normal, but would not read "ready." Could never figure it out.
This has got to be something mis-configured. I'm OK now after applying this patch but there is something simple that we are missing.
o2 checks for readiness are very simple. When the heater is functional it will pull down the resistance in the circuit and allow it to switch from low to high and back and forth. The switching itself also confirms that the sensor is "ready". You can't get much simpler than this.
