So I feel like a complete idiot and expect to be berated for this. But I swore I found this information once a long time ago, and now can't find it again.
Basically, gutted cat, need to pass emissions. I have an accessport and will figure out how to delete the CEL, but my question is that if I simply delete the CEL will the car still issue a flag on the ready state on the downstream O2 sensor even with the CEL deleted?
I'm pretty sure they plug in and look at all the errors, and just because the CEL is off, doesn't mean there won't be an error on the ready state for the O2 sensor. Anyone know if this is the case, or even know if you can just tell the computer using the accessport that the o2 sensor is fine and just report it as ready and good? I just got my AP today, but I've been reading and watching vids on it for a week and it doesn't seem I can find an actually answer to this question.
Feel free to call me an idiot while giving me the answer lol, I have to take my car in on Friday so I'm starting to get a bit frantic (I have to go to court next week with my updated tags or pay a $268 fine)
Yes you can mask the CELs and keep them from blocking the readiness monitors. I had my AP for 3 years with all cat and rear O2 CELs blocked (no cat, no rear O2, no air pump) and the readiness monitors always showed 'ready' for emissions inspection. There is more than one location to block them, and you have to block them in every location in order to do it correctly.
So, if I hop on the map and just block all CELs and take it there and have them do their test they will all read ready? Then I just re-enable all the CELs again?
I'm just going to have mazdamaniac do his thing with the maps, but for now I just want to mask those cels, go get my emissions test done and get my tags renewed. After that I'll do all his stuff. So is that feasible to just shut off all the CELs, that post 13 is awesome btw, it's a good reference there.
Your reference to a single map is where you will get tripped up. There is more than one location that they have to be turned off at, if you turn them off in one location and not another, you will not pass emissions.
If you bought your AP new from MM, AND he has his MM base map on it, just load up the base map. Everything is already blocked correctly.
Not quite, there is a single Advanced Parameters page from the EDIT drop-down menu (or use Ctrl+A) that has all the CEL codes listed. Assuming you don't have an MM base map, then for passing the OBD2 test purposes just uncheck/block everything on a Stock base map, flash the PCM with the map, drive the car until one or less readiness flags is still tripped, then go in and pass the test.

Assuming you are referring to ATR which other locations are there? i have only find them in advanced parameters. Using only the advanced parameters location passed the first time. Coming up again this year, curious to see what happens...

Well, I loaded the base MM map and have driven the car for about 100 miles, I went in to get the test and the ready test failed not ready for Catalyst, Evaporative System, Secondary Air System, and Oxygen Sensor.
I guess I'll go drive it some more, I've found some things on the Gog-el that told me some steps to follow to force the ready state. But instead of going back and wasting a free test, can the AP check ready states? Because I can't figure out how to do it if it can and if it can I can't seem to find a reference to do it.
Hmm, maybe I'm remembering wrong. I remember seeing 2 locations, and there are references in other threads that one location is effectively what enables/disables the ECU check, the other is what actually trips the light, so if you only turn off the light, it won't stop the ECU from throwing the code.
I don't have a copy available, 2 years since i sold my 8. I'll be digging back into it at some point soon when i get back in an 8 again.
Waiting on my divorce mediation to be concluded. Any major financial change prior to that point places me at risk of giving up more to my ex-wife than I have to. Nothing stopping me once those papers are filed.
Pretty sure they were referencing checking off all the appropriate CEL blocking codes in the list, not that there was another location. There isn't, not in the AP anyway ....
Yeah, It just seems that the issue now is that the ready states are still reading inc. I've done mode 1 and mode 3 of getting them to pop up. I'm going to drive to work today (usually 70+ mph for about half an hour) and just switch gears from time to time to get the rpm's varied. Hopefully some more driving will get them up because doing that ready state thing didn't work. During lunch I'm heading over to autozone and having them check it again.
I've put over 100 miles into this map, I was hoping they would read ready by now, I go to court next wed and am starting to get nervous about getting this thing to pass it.
Well, at this point I've driven over 200 miles, I've done the mode1 and mode3 drive modes twice. I've let the car idle for 20 minutes are two separate occasions. I've driven it hard...
Still, no ready states. Is it possible that MM's map masking the CELs is going to make this so that they can never be ready?
Curious, have you contacted him with the question? They were fully blocked and monitors ready on the base map he had loaded on my AP from him...
Yeah, I'm still in communication with him. He told me before I made the purchase it wouldn't be a problem. Of course now those 4 flags wont come up as ready. The CEL is blocked, but the ready state still reads incomplete.
Ok, he suggested I go ahead and replace the o2 sensor that's plugged into the gutted cat. Now, should I disconnect the battery and start over? Because I went through and did the drive cycles and it isn't ready, I've put about 50 miles on the new o2 sensor and not there yet.
