clear codes and run again and see whats what. never had that code so no.

and yes they will be set to NOT READY before. and when you clear codes...all monitors return to not ready status.

Many states allow one (and some even two) not ready monitors, including the CAT.

That's the other option...

attempt to get everything, even the evap, to finish, and then quickly park it at the shop for the scan. Many have done it, although it is a bit of a pain to get right.

Depends on the year of the car. Our cars will almost always only be one. And I failed with 1 Not Ready and Cat N/A. That even though my states allows one not ready.

The Cat was NA was an instant fail.

The Cat as NA was an instant fail.

hence the need for the io2 catsim.....

My point was, you made an overstatement which is simply not true for everyone. In PA, for example, N/A is fine, as is one not ready.

Seamus · 02-22-2016, 10:36 PM

Problem.solved. Was the cobb map. Sim works a treat

kevBquick · 02-22-2016, 10:44 PM

that was going to be my next suggestion. that the cobb map was in the way. glad you figured it out.

we should be at 100% flawless.

NA is different that NOT Ready.

means you car may not support that/or have that system. I checked 2011 335IS vs my 2011 335XI; we have very different systems. he has some NA that I don't.

NA is not the same is NOT READY.

emissions per state....thats everyone elses job to decide what applies in your respective states.

? Yes, we're all well aware.

I think you should read my post again. I said in PA, for example, one not ready is OK, as are any number of N/As.

I'm lost. How was me saying the CAT as NA is a fail in my state an overstatement? It is an automatic fail in my state.

Regardless, the issue is fixed.

That was my fault, I thought you were the guy who said this:

No worries mate. Im just delighted us N55'rs finally can get passed with DP. And Area and Kev are the two that made it possible

Cory S · 02-23-2016, 10:34 AM

So does one with an E90 AWD have it easier or harder to fool the system?

No different. My application was a 2011 e90 335i xdrive. Just follow Kev's installation guide.

Did your installation differ from Kev's since you have a JB4?

install is the same, AWD or RWD

the difference is the tune, cobb or JB4....

COBB has a backend tune that disables the monitor for cat readiness, it will show NA, this needs to be naturalized in the backend tune.

JB4, simply uses autoclear, just turn off autoclear.

prematureapex, just a suggestion.... be nice to Kevbquick, remember it's his testing and knowledge that got us this far, and he's been involved from nearly the beginning, and has direct ties with the developer of the fix. I just sense a little disrespect. just my two cents.....

kevBquick · 02-23-2016, 10:54 PM

if you guys run into any codes and you shouldn't or need further assistance...just PM me and i'll walk you through it.

we went through a long rough ride to get it to this point. i know and a74 knows everyone wanted it. it took a long time to iron out the kinks in the coding. lots of data logging. revisions of product. from CA to me. test. repeat. etc.

i won't debate your states emissions testing...honestly thats your department. i do care of if your unit isn't working right or you can't install it. as we took that into consideration as well. getting this to as basic of a unit as possible with as little wires as possible.

so lets not turn the thread into my state does this emissions and these 10 things are acceptable. great.

this is about the DP fix...and how to install it....any problems you may come across. any updates as other people are using the same O2 plug as my stock n55 unit. so colors can vary. this does work on an n54. but again color differences on wires so we need to wire trace to update schematics. THAT is what this thread is.

getting caught at emissions or what happens like any other mod or anything else is up to you. so if we could keep to the fix or and finds with other O2 plugs and wiring....i'd appreciate it.

trixdout · 02-24-2016, 10:03 AM

So if you have cobb, switch back to stock tune, get cat ready, then go for inspection and we should be good right?
