    Wish you were closer.
    Absolutely check the connections on the back side of the block. There are SEVERAL connectors back there and you can get at least one swapped or not connected. You cant get emissions done with the cam phasers not working.
    You should do a crank relearn again after correcting the cam control.
    Only AFTER, you get cam control fixed, double check you have front and rear O2 sensor wires not swapped backwards front to rear with extensions. Seen that done due to drinkn while wrenchn.
    Best luck.

    EGR 8. From a stop, accelerate to 72 Km/h (45 MPH) at 1/2 to 3/4 throttle. Repeat 3 times.
    I did get this to set but it really can't be done as it is written with the Pzero.

    I will double check what you suggested thank you...When I sent it to my tuner... he didn't seem concerned. The only thing he said is try this tune.. " I loosened things up a little bit? (i have no idea what that means.) If I hit cam relearn now will it kill my current drive cycles? Everything is now set other than the Catalyst / O2's. I am about 10 cold starts in and 200 miles in. Thoughts?

    I would think the variable cam timing is a bigger issue than emissions.

    Late closing intake allows dynamic reduction in compression. Check with your tuner if thats in the tune and if you should be going WOT to redline without cam control.

    Can you clear the cam control errors only?

    There may be some effect on exhaust make up as the cam control influences intake/exhaust overlap which massively changes the amount of uncombusted free air mixed into the exhaust stream and into the cats to help “strip” the rich cat surfaces.

    Check w tuner.
    Clear cam error and sanity check if you are FI with no cam control. Interested to hear what tuner says. Would not go WOT until then.

    Dude. Stop. If you dont have any dtc’s, you dont have any vvt problems. Also stop trying a egr drive cycle, the coyote doesnt have an egr. Doesnt have secondary air either. Aftermarket scan tools are ignorant in what they do not know and sometimes will lead you on a tangent. I am at the track this weekend, but if you want we can set up a time later this week or next weekend to get to the bottom of it. It can be as simple as a rear o2 going out, not getting hot enough, or the monitoring is shut off in the tune.. Did you already fail and get the ten day waiver?

    Okay... I changed tuners ... and within three tunes over 8 days... on the final tune it only took 21 miles over two days.... and I didn’t do any drive cycles other than go 40 for about 5 mins and for ten mins at 55...
    Everything set that first day other than the O2’s. the O2 set the next morning after taking a 7 mile drive . Lessons learned... tuning is the key and these cars like 40 miles an hour to set just about everything... it all happens fast if you can hold that 40 mph... doing full drive cycles is a HUGE waste of time... I should know I did about 20 of them in a auto they take about 2 hours... everything sets very quickly if the car likes what it see... 4E235801-D5D4-43CA-97F9-1FA3D2D453C4.jpeg

    I also am trying to get mine to set right now with the PBD emissions tune.I feel like it is waste of time.
    My thought was to load the Ford racing tune back in,as that sets very fast.
    What tune did you end up with?

    Lund was able to take care of this VERY quickly for me. Their response time during business hours is VERY fast too, I think they have 5 or 6 full time tuners now... They dialed in the car very quickly and followed a what I would call a safe procedure, while tuning the car... don't get me wrong, I like my PBD tune and Rob helped me out with a couple of build issues... However, we just couldn't get it to set... The other thing that is very interesting... with the Lund tune the car isn't as loud and that makes me happy too... I have also read some older threads where PBD was able to get them to set when Lund couldn't. At some point, I want to put both tunes on a DYNO and see what happens... :-) right now I am just happy this is behind me, I thought I was going to have to sell the car to someone in another state or put the factory headers back on (7 hours labor)... So my advice is once a new tune is loaded... go 40mph for 5 mins (everything set for me other than the EVAP and O2's / then do 10 mins 45-65 this sets the (EVAP) (this has to be done within the first 30 min.s of a cold start) on the highway... for me that set everything but the O2's... the next day the O2's set after a short drive... oh, four other things... take the key out of the car at night, do not use cruise control / be smooth on the gas, turn the key on before starting the car and keep the car at 3/4 full with gas... The biggest lesson learned for me, keep in mind I was only interested in a street car... I would have just gone with the whipple tune... and kept the exhaust factory... this is what I wanted to do but was talked out of it by the person the did my build and anther person that sold me the parts... the time, effort and money to deal with all this extra stuff isn't worth it to me...

    Good going, glad to see it worked out. I’m am in the same boat with a PBD tune as well. I have some time, so I decided to just put miles on it to see if it would happen, no dice. I think I have about 2000 miles now since the last time install and the O2’s are still incomplete.
    Curious if you had to buy a Lund nguage? I’ve been using a HP Tuners Ngauge and cant stomach the idea of having to buy another for their tune. But it would be worth it if I can stop fretting about having a car that won’t pass the test.

    SCT 4 is what I used... I did read a good thread on the HP Tuners site... it seemed like they had it figured out.... https://forum.hptuners.com/showthread.php?50900-2014-Mustang-GT-Readiness-Monitor/page3 it is a very long thread... but had some interesting points...

    Thanks, while reading that link it came to me that I had read it before, heck I think I even sent the link to Rob at PBD last year when I was trying to pass. Not much I can do being that I’m at the mercy of the tuner. Damn wonder how Lund does on Procharger emissions tunes. I have an SCT X4, so as long as they can tune for that, I’ll only have to pay for a tune and then cross fingers that they know how to make it pass. Thanks again.

    With the Whipple, I know they are very good... I would send them a note, give them all the details of your build and what you have tried... I am sure they will let you know. They told me that they were very confident that they could make it work... but couldn't go as far a as promise me anything... I bet they would rather tell you no, rather than the write countless tunes trying to get it to work... I would ask how many with this same setup have you been able to get to go ready... Have you tested the voltage on your O2's, have you done a smoke test (to test for leaks) or are there any exhaust leaks before the cats? Like I said if it likes what it see... it goes ready very fast. Lund did this with just three tunes with my setup and that included the base tune they started with. I good tuner knows what readings you need to have... a better tuner knows what changes you need to make to get there... the best tuners can read logs, then tell you what repairs you need to make!

    Bartly, we have the same system. Lund got mine to work with their emissions tune. I am stage II pc like yourself. I did put my cats back on, the beauty of running Cat deletes instead of headers :)

    Thank you for the insight.
    I did give it 1 more ride home,and still the O2 and HO2 did not set.
    I just flashed back to stock ,and then loaded the Ford Racing tune back in.
    I bet driving it to the shop in the morning,letting it cool by lunch,then over to my guy for inspection that they all set.
    I had a battery go down last year,and it only took a few shots up and down the highway with 1 cool down before they were all green.
    If this works like I do believe it will, then my advice to others is to buy a charger kit that comes with a 50 state legal tune to use come inspection time.

    That’s good news, thanks for letting me know it can work. I have the factory cats still installed so I’m good there. Do you have the DW injectors?

    Sounds like I just need to pony up and contact them and give them my details. A couple months back I pulled the supercharger and went back to stock and all the monitors were passing in less than 50 miles so I know the related sensors all work. I’ve checked the plumbing more times than I can count and don’t have any boost/vacuum leaks, so I should be good there. Thanks again for the info.

    Cool, thanks. Yep that’s what I have too. I was afraid those were what was making it not pass, if your monitors are passing that eliminates that idea. Thanks again.

    @jabrax Hey man, one more question if you don’t mind. When Lund got your tune to pass did all the monitors pass fairly quickly? When I pulled my supercharger off and returned to the stock tune a couple of months ago they all went green in less than 50 miles of driving.
