I went thru this back in December on my car.
Doug does turn off the sensors and they will fail you here in Houston if more than 2 are showing not ready.
Here's the proof.
I hope this will help clear some things up for all.
I resolved my issue by finding a local tuner to do a custom tune and not turning off any of the sensors.
P.S.
I also found that the drive cycle on my car was very short.
I went with the tech from Ford that was checking it out and it reset at 6 miles.

That doesn't mean it is the same for all cars and driving conditions.

here, in PA. We DO have two inspections; a safety inspection and emissions inspection. Depending on your locale you may or may not be required to have emissions tested. If you are in a locale that requires it, you're exempt if you drive less than 5k per anum. Our emissions testing is not just a quick sniff, it's on a dyno.
Here in York there are no sniffer tests, just OBDs, or visual.
Since you live in Pittsburgh you are required to have the sniffer test. IIRC that is the only area that requires it on newer cars.

Nope, Philly area as well. I'm in Chester County and it's required on all vintages with emissions (diesel exempt). Only brand new off the dealer's lot is emissions exempt, but at the one year mark it's required annually. With older cars (>15 yrs. IIRC) you can get Classic tags which still require annual renewal and safety inspection, but no emissions. For 25+ you can get Antique which has no annual renewal, and no inspections whatsoever. Antique is limited to daylight hours only.

I looked here and it seems even Pittsburgh is now only OBD checking on newer cars (1996+). Some older car will still be tail pipe tested.
Emissions testing legislation has always been a real Battle Royal here in PA. Which is why it's such a hodge podge of tests.

I had my emissions done last week and didn't have any problems. I did not take my CAI off or reflash to stock. It was an OBDII check and there were no codes. The only question I have is if they did the inspection with my 93 tune or did they do it when they had to reflash to stock to change my gears to 4.10. If they did it on the stock tune the larger Steeda MAF didn't seem to matter. If they did it on the 93 tune the fact the sensors were turned off didn't seem to matter. Another one of life's little mysteries....

Chris, If I'm reading you're post correctly ? the dealer cannot run the stock tune with the larger Steeda MAF ! Otherwise, you're air/fuel will end up dangerously lean, and may also go into failsafe mode..On the other hand, if they did it with the 93 octane tune ? they must have turned the rear 02 sensors back on..Or their would've been codes poping up
I had them check the system about a year ago and they said no codes so it should be ok for emisions. They had to reflash the tune to stock because they couldn't use their system to change the gear ratio in the PCM. I can 't remember what he told me about the emissions but I believe it was done on the 93 tune. I had to relaod the 93 because they loaded the 89 tune by mistake when they finished the install. I agree that the larger MAF would throw a code if they tried to check it with the stock tune. I don't know how they do the emissions check but I would think they start the engine when they plug into the OBDII Port. May be they just turn the key to get the readings. Not smart enough to figure that one out.

Yes, I had to start the car for the test. The machine tells you to start it after you scan the barcode on the doorframe and it has all the info to start the test.

I didn't request that the 02 sensors be turned off - my tune is from May 2006 - so it may be that they aren't. My exhaust seems ok; no soot or strange smells.

My CAI and tune from BrenSpeed had the rear O2s turned off. Went for emissions testing here in Texas, and got 4 "not readys", failed. Swapped back to stock air box and tune, went back next day, all good, passed, swapped back to C&L and tune when I got home.
Now, that is no longer an option with the mods I have now, namely LT headers. New tune from TillmanSpeed has left the rear O2 sensors on, and I went ahead and added MIL eliminators. No CEL for rich/lean, however, I do get DTC P0153 and P0133 every once in a while. They refer to the O2 sensor not warming up in a set amount of time, fixable w/ the tune. I'm hoping to pass emissions next January w/o swapping anything.

All this talk about emission testing makes me glad I live in California. We don't have to worry about it for 6 years...

I'm going to selfishly try to get this thread back on topic. Here in North Cackalacky we have a safety and Emissions (OBDII) inspection. Here were my results that got me a "Not Ready Rejection"
Misfire - Ready
Fuel System - Ready
Comprehensive Component - Ready
Catalyst - Not ready
Heated catalyst - not available
Evaporative system - Ready
Secondary Air System - not available
A/C System - not available
O2 Sensor - Not ready
O2 sensor heater - Not ready
EGR System - Not available
I don't know what all those mean but I do know that if you get more than one "not ready" your car is rejected. It doesn't fail but you don't get your sticker.
Like I said earlier I'm running a JLTII CAI and Doug's 93 Race Tune.
I'm wondering if I can load the factory tune w/o changing the CAI for the 15 mile round trip for inspection. What does everyone think?
Can Doug "fix" my tune so it passes? I wonder what that would do to performance? Obviously a question for Doug.
My gut feeling is that I should restore to stock for the inspection. PIA.

Thanks, Johnmichael resized it so it's more visible...gotta love patriotic *******!
Hey Karman! Did u check out the thread on the dyno tune? I got it all in SAE 1.0 (dounloaded WinPEP7 and got the files emailed to me): 288.3 hp/301.5 tq...check it out!
