You can't be the first person in Vancouver with catless DP's on a 335 car, who needs to pass AirCare. There's got to be a way!

[badass335]

I'm not. I have run the dp fix before and had no codes. Pulled it off because it altered readings when running tunes. It is recommended to not run dp sims with tunes.

[badass335]

I should also mention, I ran it flawlessly with my msd80 dme.

Yes, I know that. But I'm saying I can't believe you're the only one with an MSD81 ECU & catless DP's using the DP fix, but can't get readiness, so there must be something more to it if others with the same setup have managed to. Have you tried posting in the Canada forum in case anyone steps up?

PS I wouldn't listen to Gen_E92 much. He doesn't know what he's talking about.

I know that it works. I believe I have an issue. I think my issue is my rear o2 sensors not reading correctly. This in turn doesn't allow the lambda probe to reach readiness. If the probes don't reach readiness, the catalyst won't either. This is my thought. I figured I'd ask and see if others have ever had similar issues.

And your right, gen_e92 has no idea what he's talking about!

Just play around with the dp-fix settings and do the readiness cycle drive.

[badass335]

So finally, today I got
Lambda Probe - readiness!

One last one left!! Catalyst

[Lotus99]

So whatcha think the problem was?

Seems like there is no real issue. Just takes forever for the car to do its check! I finally got a cat error today! This means, increase dpfix strength and go all over the cycle again!

This was 5 days of driving 60-75miles a day through traffic, highway etc.

[badass335]

So still trying to get readiness and not achieving it. I was getting 2c7c 2c7d errors so replaced both my rear o2 sensors. I reset all adaptations and got the cat inefficiency errors again. Increased strength on the fix and tried. Codes again. Have maxed settings out and still errors. Running out of ideas!

In the US most states let you pass with 1 monitor not ready. If that's the case in Canada use your Cobb to disable the codes so you won't get the SES light and go for a check after you get all but 1 monitors ready.
I did a similar thing but with the OFT and without using any DP fix but I am in the US.

[badass335]

Our aircare laws are similar. We can go through our testing with 1 monitor not ready as well. The issue I have is that i end up getting the 29f4/29f5 codes not far behind after getting all the other monitors to ready state. My problem is that with Cobb or OFT, the engine light is eliminated but the code does exist in the error logs. Our aircare system here will fail us if there is a 29f4/ 29f5 code even though there is no engine light.

I don't know about Cobb but with OFT, if the code is disabled then it doesn't show anywhere, even in INPA. I had another set of codes that were popping up besides the standard cat codes and had to remove them as well. As soon as I flashed the updated binary they did not show in my diagnostic tool. When I flashed back the old bin they were shown immediately as if they were always there but the ECU did not report on them.

Are you sure the codes are still reported or are they just in the history log? You should be able to clear the history if that's the case. I would imagine the codes should not show when using Cobb since both OFT and Cobb change the same thinks in the ECU as far as I can tell.

[badass335]

Not quite true. OFT or Cobb can't really code out anything to do with emissions. All they can do is hide the code.

3. By doing step 2 the ecu will never clear 'readiness' which is needed to pass OBD emissions.
4. Buy BMS DP Fix so the ECU can get into it's ready mode.

Is this correct? Cobb users still need the DP Fix to pass emissions?

If so does this mean we need 2, 1 for each DP?

[techwhiz]

Sorry to hear your pain.
But for a baseline.
With a completely stock car you can achieve readiness in less than 100 miles.
I removed my Cobb to go in for a SMOG test. ECU was reset and less than 100 miles later I was ready.

So if you are having issues with the drive cycle it's not that it's difficult to get there, some mods like the DP and COBB are preventing you from ever being ready.

I have heard mostly bad things about catless DP and checks.

[badass335]

Maybe I'm doing something wrong here. Let me go over the steps again.
The dp fix install is right. I tried 1 o2 sensor and let the other one alone taped up. The understanding is that the fix will split the voltage readings from 1 o2 sensor for the ecu.

I tried 1 and went counter clock wise to 1pm (max) and still got 29f4/29f5 codes. Trying the other o2 sensor wire now.

Procedure:
-started at 5pm. Installed and reset all adaptations and cleared code.
-got the code so reset code and adjusted fix to 4pm now to make it stronger.

The understanding was that I keep going till the error was gone.

Now the one thing I want to make sure is, do I need to make the dp fix stronger and then RESET o2 adaptations or do I just clear the codes and see if the stronger settings work?

So when you go to 1pm the wires are facing away from you? The codes say too weak, so only thing I can think of is you are not having the wires facing away from you, or it is a bad dpfix.

As per instructions, wires facing away. I'm starting to wonder about that as well if in fact the unit is defective. How would I test it? I'm almost to the point where I just throw in my factory dp's and go through emissions!

[xtrackdog]

Any luck? Update please.

I have no codes, and am having a heck of a time to get the Catalyst and O2 sensors to ready state.

[badass335]

Sorry man! I gave up. Since I had cobb and running stage 2+, it expands the cat readiness parameters so it never reaches readiness. I took the car in with 1 monitor not ready and actually passed BUT then since they were doing training for a new employee, they did an overide and ran a sniff test, which I failed! Bastards!! Then they decide to blacklist the car! In order to pass, I HAVE to go through a sniff test!

Got pissed, went to shop in the morning, got factory dp's installed, drive straight there from shop, passed emissions, went right back to shop and had dp's re-installed!

Also, honestly, to get these ready, I drove a lot! Just normal city driving. I must put almost 1000kms trying to get ready, code, adjust, reset and try again.

Thanks for the reply.

I'm in the same position. O2 and Catalyst sensors not ready. Evap came online a few days ago.

I have no fault codes, but am beginning to think that the sensors will never be ready.
