So BM3 Released a new feature, you can pick and choose which codes you want to remove.

you guys think this will be a alternative to set all the readiness monitor or at least 3/4 for some states for people with catless DPs?

post here if you guys tested it out and confirm if it works!

My understanding has always been that code removal is different from readyness monitors; has something changed? I am pretty sure if there was a way to "hack" the readyness monitors to be READY/PASS even when the system being monitored was not in factory spec that would be heavily advertised. Removing CEL codes is very different.

On the facebook bm3 page. They announced a new update with the selective code deactivation.

Bump..., curious about this too!!

I'm pretty sure all this does is suppress the CEL for whatever codes you choose. Basically it's the same as what they were already doing to suppress the CEL for a catless DP but now expanded for other user-selectable codes.

Yup that is my understanding. As i have thought about it more, i am wondering why the developers have not yet been able to "hack" the ready monitors. It seems like, on a very over simplified level, they should just need to change the parameters that the ECU needs to see in order for the monitoring to be in READY/PASS such that it would be READY even if you had a catless DP. It's probably much harder than that, or else it would already be possible.

Great way to lose your ability to offer your services in most states...

Short answer: no
long answer: no

These tunes are already illegal in CA for sure (as with nearly every single aftermarket part, as you see from the disclaimers on the manufacturer websites). You have to go through a strict CARB approval process to have any modification legal in CA.

Not sure about other states, but i am pretty sure any modification that affects emissions at all (e.g., tunes, DP, etc) are technically not legal. If people were concerned about this they would not be buying catless DPs lol.

No some tunes are but its because they barely change anything and cant at idle and part throttle cruising speeds etc etc, usually a waste

Modifying your vehicle, then reverting back to stock to pass emissions test vs developing a means to circumvent emissions testing are two different things...from what I've heard, it didn't work out well for VW

We're not talking about an OE here, we're talking about the aftermarket lol. I would agree that a OE should not be allowed to embed programming (or any other means) to change emissions and performance based on "knowing" when the vehicle is being tested for emissions (i.e., the VW example).

In the case of the aftermarket, the only difference between the two scenarios is that you drive with your OEM DP on for one day in the former case? I guess I don't get the point you are trying to make.

For the sake of discussion, what is the difference between:

1. Tune that does not modify emissions-related ready parameters

2. Tune that does modify emissions-related ready parameters

When the tune is technically illegal to run with both cases, and the actual emissions related to running the tune are the same in both cases?

Not trying to argue, just want to discuss

I am all too familiar with the emissions game, not only because i have a highly modified (catless) 3000gt in CA that is subject to CA emissions testing (including sniffer emissions test), but my career is also centered around air quality and climate change.

This is highly illegal and PTF could be fined significantly if they did this.

I am not saying they should do it, it was more posing a question as to why they haven't. So i guess you are saying they probably can, but won't, for fear of repercussions.

Any mod that affects the emissions system is illegal anyways.

HUGE fines associated with that sort of thing. They likely wouldnt be able to afford it.

Technically huge fines associated with removing the cat as well

True..but, the purpose of the hardware is not to simulate and or create false readings to bypass state testing equipment.

As you know, normally...if your exhaust is modified, and you go in for your emissions certification...you'll fail.

This is where it depends and not always true. Lots of states allow you to modify as long as it still passes the test. Some states do a ecu scan for ready states and codes. Some actually do the sniff test and see the emission numbers etc etc... some do visual inspections for oem hardware etc etc...

Not every state is California...

Fair enough...


Thank god! When my daughter and son-n-law visit, I make them wear hazmat suits or they have to go back home....I'll buy them new clothes when they arrive. I don't won't those germs in my house...true story...

Indeed, and every shop within every state is different to a certain degree, especially on the visual inspection and non-quantitative tests (sniffer test and visual). But in terms of modifying the emissions system (cat, evap, EGR, etc), EPA regulations apply in every state. So, even if your state does not require emissions testing, tampering with any of the systems is still technically illegal on a federal level.

This is just part of the game we all play in the modified car world. Personally, i went with the fabspeed catted DP because i didnt want to play the games with my BMW that i have to with other cars since i am in CA.

Just removed the annoying MAF code which is due to my custom intake that always used to pop up. This feature is awesome! Thank you!!
