Default Help - Stage 2 OTS Emissions issue (Not Ready)

Hello -

So I have recently put on a Catted Turbox DP onto my 2016 WRX. The OBD readiness will not set for my emissions here in PA. Does anyone know if there is anyway around it or if it would eventually set. Cobb states the readiness will never set with the stage 2 map. TPG said it could eventually set, I also let Moore Performance take it last night for a 70 miles trip and they didn't set. Any one have the same issue with the Stage 2 tune? Do I need to re-install the stock pipe? There seem to be a lot of heavily modded cars that still passes. What gives?

Have you tried to see if it will set on the stock map with the catted DP? You can certainly run it without an issue for the purpose of getting the car inspected. If the catted DP trips the CEL, you can do most of a full drive cycle until all monitors are off sans the O2, and then park it at the station to be inspected before the light trips. The O2 takes a couple drive cycles to complete, whereas the rest of the monitors can be cleared sooner with the right type of driving.

However, do you only have 1 monitor not-ready? If so, you're allowed 1 in PA...so you'll pass as it sits now.

It isn't really just how many miles you drive but also the number of cold starts or something like that. I'm pretty sure you just need a little more time and it will read clean.

Well I actually have the Stage 2 + Big SF tune. The EVAP, O2, and Fuel System, aren't set yet, Catalyst was set. It's been a week and a half since the reflash. I have less than a 5 minute commute to work daily which could be root cause. It could just need driven more...I was told I could drive around on the Stage 1 + Big SF tune carefully and out of boost to get them to set, I'm afraid to do that to cause any damage to the motor...

Running the stage 1 map is not going to cause any damage to the motor, at all. Shouldn't even remotely be a concern. Less boost, less timing. You're fine. Sure, stay out of WOT to be safe, but even that shouldn't be an issue really.

That being said, yes, it's your drive. I can get all the monitors but 1 done in a single sitting, maybe 2 if the evap is being a jerk.

This isn't for a Subaru specifically, but they are are generally very similar. You need a long cold-start idle, slow/steady cruise, acceleration and highway cruise (once you pass 80 mph or heavy throttle, it resets), long decel and idle.

A 5 minute work commute without these things in mind will make your wait on those monitors very long indeed.

Thanks for the help. I'll give it a go. Maybe I'm just overly nervous because my stickers are up at the end of the month. I'll try a couple drive cycles myself. Appreciate it!

No problem. Just remember, the cold start really means a cold start. Like almost fully-cooled engine cold.

The only system that never reset for me was my EVAP. I'm in PA too and as long as it's only one system that isn't ready, they'll pass you. Do the drive cycle defined above and your systems should show readiness...at least enough of them anyway.

Ok, so I was just in the same exact situation and on my 2015 I had to reinstall the OEM DP (among other parts). My tuner explained to me that it had something to do with the rear O2. I really want to find a way to maintain my emission readiness without having to reinstall any OEM parts. I am an emissions newb tho

Sounds nonsense. I'm FBO, egr/tgv deleted, high flow cat. All my readiness monitors show ready.

I had a similar uh... problem with my gti. Stage 2, etc. In order to pass emissions I had to flash back to a stock non test pipe file and also add spacers on my o2 sensors to trick the flow into thinking my high flow cat was actually the stock cat. I am not versed enough subaru to give you an idea on how to do that with this platform though.

I had this problem on my last car and I had to unmarried the AP to pass NY inspection (stock cats and emissions). The car was MAP based so it was safe to drive stock Tune with bolt ons.

I've tried to ask e tuners about this since I will need an inspection friendly tune ( with catted J pipe) and so far they don't really seem to know. I couldn't find a list of the e tuners that mentioned if they allowed readiness monitors to be set.

Based on responses it Sounds like we may be able to commute in the car with stage 2 mods on a stock Tune for inspection. I'm watching this thread for your guys expertise.

All just to update from my first post. All but one of the monitors in now set, which is the Fuel System. O2, EVAP, Catalyst all finally set after some Drive cycles while still running the Stage 2 OTS map, my only one not ready is the Fuel system but I'm hoping after one more drive cycle that should set to. Good luck to everyone. Most tuners I have checked with have told me in most cases with a quality Catted system, the monitors should set. I checked with COBB but they told me it wouldn't set unless it was a stage 1 set up. Turbox told me it should have no problem setting with their pipe. TPG and Moore Performance here in Pittsburgh were also giving me different answers. No one seems to be on the same page with this situation...

As long as your cat is before the 2nd o2 it will set

As said previously, most states will allow 1-2 monitor to be "not ready" and you will still pass. Check on that for PA...you may already be good to go.

I'm having a similar issue. I purchase a 2016 WRX Limited last year from SC but I'm trying to get it inspected in NC.

It has the following engine modifications:
- Stage 2+ Tune from Bren Tuning
- 3" Cobb Catted J pipe mated to a OEM 2.5" STI exhaust
- Grimmspeed Top Mount Intercooler Kit w/ Splitter
- Grimmspeed verti-cooler
- Grimmspeed Charge Pipe Kit
- Boomba Racing Blow Off Valve
- Cobb Big SF cold air intake
- TGV deletes
- EGR delete

The EVAP sensor and Oxygen sensor keep reading as "Not Ready." I've tried resetting the ECU and following the steps below but these 2 sensors still show not ready. Any ideas would be much appreciated.

1) As soon as the engine starts, idle the engine in drive for two and a half minutes with the A/C and rear defrost on. OBDII checks oxygen sensor heater circuits, air pump and EVAP purge.
2) Turn the A/C and rear defrost off, and accelerate to 55 mph at half throttle. OBDII checks for ignition misfire, fuel trim and canister purge.
3) Hold at a steady state speed of 55 mph for three minutes. OBDII monitors EGR, air pump, O2 sensors and canister purge.
4) Decelerate (coast down) to 20 mph without braking or depressing the clutch. OBDII checks EGR and purge functions.
5) Accelerate back to 55 to 60 mph at 3/4 throttle. OBDII checks misfire, fuel trim and purge again.
6) Hold at a steady speed of 55 to 60 mph for five minutes. OBDII monitors catalytic converter efficiency, misfire, EGR, fuel trim, oxygen sensors and purge functions.
7) Decelerate (coast down) to a stop without braking. OBDII makes a final check of EGR and canister purge.

You could call Bren and see what they say. They're usually very helpful.

Also, you either have a Grimmspeed TMIC or a Process West Verticooler. Grimmspeed doesnt make a Verticooler and you cant put two TMICs on one car (with thr stock setup). Its one or the other not both.

Angry I've been having this problem for 4 months now

I had been driving with the Stage 2 BigSF+ OTS map for almost a year, i believe i passed the inspection a week after i installed the Invidia Catted J-Pipe, with the Invidia R400 Catback.

I had disconnected the battery to install the IAG AOS, (as the instructions suggested) and since then i haven't been able to get the O2 Sensor READY.

i've tried all the drive cycles known to man. i've gone to different shops for recommendations and even different maps, to try and get the I/M Readiness fully READY. I've failed the Inspection twice due to not being ready. EVAP depends on O2 sensor readiness.

I've tried the Mechanical Fix (thinking that the High Flow Cat was too High Flow) and i get a Low Voltage CEL from the rear 02.

I'm currently running the OEM J-Pipe, with a non-stock map, almost for a week, 200 miles and all specific drive cycles. and the 02 system is still NOT READY.

My next step is stock map and more drive cycles.

potentially i have bad O2 sensors and i need to replace them. does anyone know a reliable site to order them from incase? haven't been able to find the part numbers for both in the docs.

2017 WRX
Cobb BigSF
grimmspeed TMIC
perrin charge pipe
Invidia catted j-pipe
Invidia r400 catback

after trying various changes with the stock map, without success, i reverted the j-pipe to the stock j-pipe, and low and behold i had a very Happy Thanksgiving, the drive might have helped with that :joy:

I'm all good now, just sucks i had to revert the pipe. don't want to do that every year to pass inspections.

So I'm dealing with smog test in CA. I got flagged to the referee. It seems like they only do a data check. From what your describing I can theoretically leave my catted invidia dp in and reflash to stock and get the monitors to set and complete? Or is it best to but back stock parts and uninstall AP?

I am in a similar boat. I am new to the California emissions battle.
My O2 sensor will not reset. I'm hoping that a reflash to stage 1 will fix it.

Are you guys in correct forum? From what i heard Cali doesnt do emissions for new cars that are 8yrs old or less, in my state its 5yrs.

So what gives? Is it 5yrs old and it is a 2015?
