When your hand-held tuning device (the ford racing pro cal) has an EO# C.A.R.B stamped on it? this means that it's 50 state emissions legal. Also note, that as long as your vehicle passes the OBDII emissions test? any hand-held tuning device which doesn't include a certified C.A.R.B # is legal for use with the exception of California. However, that may very well change if the EPA is successful in it's attempts to impose restrictions upon the aftermarket performance industry
When there is an approved modification done by a dealer, the have to put a label on the pcm itself. I had to fill out those labels when flashing updates/fixes under warranty.So do you mean the hand-held device itself should have the EO stamped directly on it? I think I only had the sticker in the box with it, that is placed in the engine compartment. The hand-held unit itself reads from a memory card, so it seems like someone could put a noncompliant tune on a card. Not sure how stamping the unit itself could control that?
And this is an example of a defeat device.
No judgement, but this is exactly what the EPA is after.

Do the big daddies mini cat 02 extension's plug into the rear O2 holes.... with the oem rear sensor then plugged into the mini cat extension ?? Once in a while I get the..OBD code spat out for... ' rear O2 sensors not ready'. I tried those extenders..to no avail, made no difference.Judge me all you want, I'm a big boy and know what I'm doing. lol. I'm currently using the big daddies mini cat O2 extensions to defeat the OBD testing and they work great.

Any carb stickers for boltons, just went under the hood somewhere. Usually near the emission label.
The sticker provided is proof of "certified condition" of the tune file when loaded into the PCM..
A tuner can actually do EPA legal performance tuning w\o being "certified" by EPA or CARB, just need to know what not to touch\alter in the base OEM thus EPA\CARB legal tune file to retain legality.

As the other posters have mentioned, the EO# number is a sticker which validates the calibration tuning file in the Ford Performance tuning device as 50 state CARB legal. You place the included sticker in the engine bay as you mentioned and your all set. However, as also mentioned by the other posters, if a non-compliant tune is somehow flashed into the device thru a memory card and then uploaded into your vehicle's ECM? your CARB EO# sticker is no longer valid. Therefore, just something you may want to keep in mind for future reference
Ok, thanks I do have the under hood sticker, just nothing on the programmer itself. The SD card carries my VIN though.
As long as they don't disable any emissions specific monitors or the programming that these monitors operate off of in the tune's IM Readiness (the OBDII monitors that determine passage or failure) or change the closed loop OEM set AFR target (the target that the PCM will try to maintain....the approved EPA\CARB AFR for emissions requirement) or alter any other programming that may alter operation of other non-emissions specific devices\components (such as the VCT system as it is not monitored in IM Readiness but this system does perform an emissions task--EGR--as well as performance) that may have an adverse effect on emissions that may cause an OBDII emissions check to fail, it is legal to make tuning changes for maintenance or even some performance related reasons. The 1st 2 things I typed are dead ringer illegal (IM Readiness & OEM closed loop AFR target), the 3rd 1 is where the grey area as tuning is concerned as it will depend on how much alteration is done to actually cause the adverse emissions effects....... The issue w\ gas\diesel powered engines concerning emissions is during low speed, low RPM operation (daily driving) as this area is where these engine's operations are the least efficient...especially V6's\V8's (or larger displacement engines) as they only become very fuel efficient at higher RPM's where the HP\TQ peaks occur due to more accurate & stable airflow measurement thus better metering of fuel & more complete fuel burn due to more stable combustion chamber temps as a result. This is what\why the cats are installed for as these engines can't pass the emissions targets on their own w\o them at low speed, low RPM usage. I'll say it again.....low speed, low RPM usage.Going to have to explain this one a bit more for me. How does the tuner know they did not alter emissions? Of course I assume they would not alter them as much with all emission equipment in tact, but they are not allowed to alter them at all, correct?
Well my fellow Mustanger, you'd think it not to be but..................................This is not hard to wrap your head around. If the emissions control devices are present and functioning, not deactivated, deleted or defeated in some way, it's not out of compliance. The EPA has only expressed concern that the emissions control systems are not defeated.
There is no EO# stamped on the programmer itself. So just disregard my original post response, it was incorrect!
That is a valid concern. Let me add my experience working with the 11&up copperhead pcm. This pcm is a brand new animal compared to prior years. Ford did a very good job with the stock tune, and there is very little if any gains can be had just from tuning. Any gains one thinks they got from just a tune is probably a placebo effect. Conventional tuning approach does not work well with the copperhead pcm. Not going into details, that discussion needs its own thread. But this pcm WILL deliver the specified WOT AFR, and put the most timing to it based on the knock sensors, optimal safe for the engine performance. Unless ofcourse the "tune" disables these safeties.....and that is a whole different story.When I've looked at even newer cars like the '11+ 5.0 cars, I always wonder if they have ever been tuned and personally value them slightly less if so.
