OBD2 Readiness Monitors with Tune

[choate]

For the most part you guys are wasting your time. They’ll likely never go ready. You’re going to have to go back to stock. Been through all this before. The solution was to drive it more. New revised tune. Drive it more. Nothing changed bc the heated cat and one or two others never set to ready. Put it all back stock and within like 20 miles they all set ready

so ive noticed lately that on my 91 performance tune from lund all my sensors show ready. its been thousands of miles but they are now ready. disclaimer...i have o2 spacers that i left in place during my attempts at passing emissions with LTHs. i was able to pass by going back to stock tune and installing the o2 spacers did one drive cycle and they all reset ok. but i looked the other day and everything showed ready with the tune back on. so spacers may be the key. i have the 90 angle ones but only used the straight portion

Torque is supposedly a great application, and I believe it is only for Android users. I forgot the name of the app I use, but just type "emissions" or other similar terms into the Apple app store and see what comes up.

The cheap OBDII Scanner I have is called "ELM 327," and can be purchased on Amazon. It has come in handy many times! I used it on another non-Ford vehicle when it was throwing misfire codes so I could go to the mechanic and not get ripped off.

Thanks for the info Joe. I have an old ELM 327 and an OBDLink MX Bluetooth dongle that both do a great job! I just researched it and figured out how to check emissions readiness in the Torque app. I have an android(Samsung S8)

So you went back to stock tune, had all emissions monitors set to "ready," and then the monitors remained "ready" when on the new tune?

they did not remain ready but after i passed smog on the stock tune i did leave the o2 spacers in place and just put my performance tune back on and after awhile of driving normally not thinking about it i happened to check and according to my ngauge they had all set to ready. this is prob over the course of maybe 2k miles

Just bought a set of spacers. I'll see if they help in any way.

In for results on spacers.

Anyone know what are the tuners doing there? I only have a CAI and tune and never could get mine to show ready. I even went through the specific driving procedure for giggles and no luck while on a tune. Even got a tune revision. The only fix was going back to a stock tune. It reset everything within a day so, I think. But... it runs so good on the tune. I can't bring myself to put it back stock permanently

So I took my tune off for now. To me, if tuners can't get the car to play nice with emission devices, then how do I know if they are doing anything right? They already sent a revision. On top of that, I have to do a crank relearn every stinkin' time I change tunes (even going back to stock). I'm about to take a road trip this summer, and decided it was a good time to take it off. I'm thinking about long term... reliability vs performance.

Most tuners can get the sensors to go green on stock headers with a tune. It's once you go long tubes that the O2 sensors move further down stream and require extensions on the secondary O2's so I think the voltage doesn't match up to what the car is looking for. That's the part they can't figure out.

Just so you know, I passed inspection with a flex fuel tune with all the emissions stuff grayed out as "Unsupported" in north Austin.

In for results on this. I'm probably going to end up going this route too.

Hey Zelek, dont see where I ever replied to this. Never got it to work with the cat material extension.
Lund sent me another tune and told me to take them off. I did put my cats back on. Worked like charm. Went through drive cycle, the 02s and cat set before the fuel and evap . Next day redid the cycles specific to those two monitors, and they set. Worked like charm.

Maybe the extension aren't needed for boosted cars. --- Grayed out, pretty friggen slick LOL

How did your tuner achieve this? My O2, CAT and HO2 are red because I’m catless long tube headers. If I could just get the tune to show them as unsupported instead of not ready I could pass.

I probably noted it elsewhere, but my solution was to change to the Ford Performance Power Pack 2. I never could get the VMP setup to get compliant. To be fair, VMP did note on their website that the original tune was for “offroad only” and they weren’t kidding around. But then I am kind of surprised they couldn’t fix that in a revision since all I had was a CAI.

I’ve got a whipple, catless headers, X pipe etc. I don’t want to have to swap manifolds. It’ll be cheaper to register the car in Montana.

The best way is to ask your tuner to keep all catless codes and emissions checks to stock, then put on catted o2 extensions on post cat sensors on catless setups, empty or catted o2 extensions on hugh flow catted setups. This alone will trick the o2 sensors to get into ready status without problem almost always as it was oem.
The easiest way is to make the car think its properly catted and it will pass easy, alot of tuners will not properly bypass catless codes so this is where your problem lies (especially lund, i dont believe they do any real catless remedies)
