Yes, I know, tune them out. Here is the problem, its been tuned by two different tuners and it always comes back with the CEL within 100 miles. 420 & 430 I think? Is it a lot more difficult than just setting the code to disable? It always makes my fuel mileage drop to crap.
HP Tuners, and I'm sure I can get a copy of the tune on a thumb drive or the likes when I take it back to get it checked. Okay, so he needs to set this 06 to '0' instead of '3'. Hopefully that'll work and if I get the tune I'd love to get some feedback.
The actual data in the ECM itself needs to be a value of 00, I just called a friend with hptuners and he says they have a dropdown box with 0-3 as the selections. with 3 being no error reported.
I would follow these other guys suggestions, I do not know the hp product that well.
I dont know about newer cars, but on my 96 Talon all I did was take the O2 sensor out of the exhaust stream and safety wire it to the side of the exhaust, then plug the hole that was left by the O2 sensor. Its been this way since 04 and has never thrown a CEL and its not on the computer when I run a scan tool on it.

seth in with thaaaa win..
on a side note... 420 and 430 are disabled in my tune...
So that wont work? Have you tried it? The talon is still OBDII. Im not sure how the ECU sees the O2 sensors on the GTOs. Its worked on other cars as well...

So all of these codes have to be set to no error reported?
Cause you're one of those lucky kind where things just seem to happen right? Generally speaking on experience, if it can go wrong, it will go wrong on my stuff.

Beats me, I've never tried it. I just thought that was funny the way you said it. IMHO, however, there's a half-assed way to do something, and the right way to do something. Half-assed ways of doing something should be left for other cars.
Just a guess though is that it won't work. Do some searches and see if you can find a post here where someone did it, and it worked. These cars have been out for six years, so you'd *think* there'd be one cheap SOB in the crowd who's done it...if it works. I don't read every thread here, but I read quite a bit. I've seen people buy "O2 simulators" or something like that, but don't ever remember anyone saying they did what you suggest. Could be wrong though. It's been a bad day.
the honest answer is likely very unscientific believe it or not..
some cars are just more finiky than others...
its the likely same reason that the old school casper's o2 sims worked 90% of the time, and for that other 10%, they ended up still needing to have the correct codes tuned out...
you may also recall, in cars with hi-flo cat's they will actually intermitently set these codes as well...
on the other hand, if you were looking for an absolute answer.... i don't have any of those...
that answer would require knowing what threshold the cat efficency checks itself against... (likely a delta o2 fluctuation) and if its to0 low or too high, it trips the code... just a whole lot of best guesses...
