there are no inspection stickers in CA, only reg stickers on plates. Also don’t refer to smog as “inspection”, So yea, def not in CA

 

It’s not just about the forced pass issue though, right? Ignoring the OBD monitor issue (which the forced pass was designed to address), it sounds like any modification to the ECU (like a basic tune which nearly every Evo owner has) is going to trigger a CVN fail. So this seems like an issue for nearly everyone.

Curious to know (1) if someone can confirm that CA is now checking CVN values during a regular smog (my last smog was in June 2018 and they obviously weren’t then) and (2) whether the CVN values can be manipulated through a tune.

Reverting to a factory flash is a non-starter for most people, particularly those with cams.

 

Theoretically you could code it to return what ever CVN you wanted to just like monitor status etc.

 

Oh please sweet baby Jesus let the gurus have the ambition to come up with a solution for this. 🙏

 

Seconded. It certainly seems possible since people are doing it for other OEMs. For example, BMW: https://chiptuningtools.net/index.ph..._article_id=11

 

If someone wants to teach me, I'll take the time to do it I don't even need it any more, but it would be awesome to have a fix for everyone else.

 

I am casually learning embedded software engineering, it's not exactly a light subject lol. I find these youtube channels to be especially good.

I’m definitely willing to pay $ to who ever can come up with a solution for this! I can’t seem to find my original rom the only one I have seems to have the boost tables modified

 

I’m surprised that none of the tuners out there are not chiming in on this

Thank you Bryan. You have always been very helpful.

 

Thanks to all who are willing to tackle this issue

 

Now.. if we could remember which of ours is OEM, since it's been about seven years LOL.

 

Use whatever is acceptable for the year, not that hard.

05 only had 1
06 had 3, use the latest as that will be all TSB's.

I honestly cannot remember how many 03 and 04 had. Again, use whatever the latest TSB was when in doubt.

 

Good news. Mine is 05 so I can hit the easy button. But this all still means going back to completely stock, and having to drive the car the required miles for the monitors to register and pray to the new gods and the old gods that they ring in our favor. This might not be so easy for those who’s registration has lapsed.
