I have to take my 2011 135i to a STAR station in the next couple of months. I've been running MHD, but uninstalled it to prepare for the SMOG test. I noticed that after uninstalling MHD and checking for codes it displays the checksums... which don't match. I'm concerned that I'm going to run into the same issue as you. Has anybody actually had recent luck uninstalling a tune and passing SMOG?

This raises another question I hadn't considered - where is it actually storing the stock tune? I've changed phones since originally installing MHD so it's likely I've lost my stock tune forever. |

Saying that, this might explain why you are seeing the checksums that don't match. I'm going to revert to stock tune this afternoon to check since I've only ever had one device I've used with MHD. Are the checksums automatically shown after checking for codes? |

I made a post in the MHD 1 series thread. Hopefully we get a response there.

Here's a screenshot from MHD. You can see the "Factory software" and "Current software" when you check for codes. I assume these are supposed to match and they don't because I uninstalled MHD from a different device than I originally installed it with. |

Can you please post this on the e90post MHD thread? That’s the only way to get a response. Or anyone that has ran into this issue, that is the best place to get this answered. I would do it but the issue hasn’t occurred for me so I am not the best person to articulate what happened.

Or, more likely, the guy who started this thread isn't being completely honest and he failed for normal, legitimate reasons like visual inspection, emissions not in readiness state, etc.

Like I made this all up to be without my car for two and half months, pay extra $1800 for smog test? Seriously, what is your theory on my motivation for posting this? I need attention or something? Think first, then post, it's pretty easy. |

New cat still throws the cel pretty much immediately and never went away after two years. Since pandemic I drive 90% less, no track days, no meets, no commutes. I think this guy zygote sucks. This is why I don't social media, mf's like that. |

I've owned modded BMW's for a decade and have never had a smog tech jack the car up to check for the secondary cats... now I'm flagged and need to get some cats welded in the mids. I'm wondering if my car is flagged forever now? Will all future smog techs see that I didn't have secondary cats at one point and my car was "tampered" with? |

Looks like aftermarket tune is going to be an issue going forward. I wonder if DIY PPK or MHD reset to stock would pass.

I heard about this. Crazy. So I’m wondering if they see the car has 98G0 be installed it’ll be fine or if they can see MHD is installed as well. Hopefully some of us will get some experience and share what happened.

Is it worse to have a tune for smog? or no secondary cats and modified exhaust for smog? This should answer alot of people's questions for future mods and help other owners debating whats better in california.

I recently passed mine without any issue, reverted stock intake, CP, DP, and removed JB4/uninstalled MHD. I had a different software version, but I don't think it matters. FMIC was still on, and no second cats. Just getting that drive cycle was a PITA. GL!

I failed at the referee 3 times before i realized it was my m3 gauge cluster causing the problem. It was giving a checksum error that wasn't matching what came from the factory. Swapped the cluster back to the stock one and it passed no problem. California smog is getting out of hand!!
