A) TF is your problem?

B) The comment I was replying to said you can't use the 1 series cluster. Which I was rebutting, as you can, you'll just lose those two indicators.

A) People who contradict themselves trying to enlighten others
B) Show me an E82 w/S65 swap and 1M cluster with functioning MDM

I put the M3 cluster in mine but for initial testing I used a 135 cluster and it works as I described.

The MDM button is in a CAN packet that comes from the SZL, which the MSS60 then sees and sets the M Drive options in CAN packet 0x399 which the transmission and various other modules pick up to set settings. The Kombi simply looks at two bits of the 0x399 packet to turn the green M and yellow MDM on/off.

None of it relies on the Kombi to function at all. MDM would work even if you didn't have a Kombi plugged in.

Sorry, I didn't realize you don't actually own a 1M, but thanks for the more technical description of what you've done

Why did you go with the M3 cluster?

I don’t know why people want me to use a cluster that doesn’t show my redline or rpm sweep!

I am debating the M3 cluster, I have another one that could use it 😊

I don't own a 1M... not sure if that's supposed to disqualify me or something but I do own a home built S65 swapped 1 series. And did reverse engineer the majority of the PT6 CAN messages, and did work on an extensive project with a lot of smart people to try to fully enable MDM on non M cars without the MSS60.

I went with the M3 cluster so the redline would be correct. I also don't have iDrive like OP so the indicators are important to me.

Sorry, I know the back and forth with the other guy isn't helpful, I wasn't saying you should use the 1M cluster, just that you technically could. I like your solution a lot. The M3 cluster is kind of messy to get to fit in the 1 series bump. My car is mostly just a track toy so it doesn't bother me but the digital cluster in yours is way cleaner.

Yeah I really didn’t want to hack up the oem M3 cluster but analog gauge are super classily!

Another option I mentioned in another thread somewhere is to just swap in or remove the black section bits from between the two dials and just put the m3 guts into the 1 series housing. It does fit, there's just a difference in the screen/indicator lay out.

I tried this very briefly but didn't explore it too much. I ended up just cutting the brim off the M3 cluster and the 1 series cluster and gluing the 1 series brim on the M3 cluster. It looks good if you're not looking for it.

Drove her around, so far so good. Time to expand and build more oddities 😁

No doubt, it sounds like you've done some digging to understand the systems in these cars. As a fellow digger, I can tell by your posts that you don't own a 1M; because they didn't properly document the car.

Even in your non-M 1-series you wanted a functioning cluster, which is why I'm surprised you're recommending someone building an actual E82M go with something less than fully functioning

The car is very well documented if you Google my username and M1.5. I just haven't gotten around to porting the build here because the picture upload stuff is a nightmare.

This is the issue you're having... I didn't recommend anything. Go read what I said. I simply said you COULD use an E82 cluster if you wanted to. I don't know what your problem is but I'm done muddying up OP's excellent build thread with your bullshit so I'm not going to reply any more.

You're pretty good at projecting buddy. I'm sorry you got so upset about me being confused by your post(s), hopefully you can forgive me. I even said you clearly have done a lot of work digging into the cars. I guess some folks just can't take a compliment. I'm not sure how you equate your N55 135i build to documenting the 1M, they aren't the same cars.

Thanks! Excited to see how much more we can ruin 😂

any updates? and how's the garage looking?

We have been so busy moving and prepping the new garage.

Sadly there are still a handful of items that need to be fixed. Nothing major but I want it 100% proper. Then White car gets Ruined.

Been a minute. Actually driving her , getting AC charged, and breaking things.

New finding is that the casted part for the M3 front tower bars will not work. Even with it being 3 series up to the firewall, the coupes front has a steeper angle at the center bolt. Now we know why the 1Ms bars are half M3 half 1 series 😂

Had to remove the Dinan CF bars 😭

[WrathOTM]

Damn that looks so friggin sweet man love how the engine is looking! Was wondering if we were going to see any updates.
Are you keeping the intake runners exposed or you coming up with a housing/filter for them?

HP Autosport do a modified M3 bulkhead piece for the E8x. I have one, it’s a nice piece.

Edit: The lower cowl trim piece (that the M3 bulkhead mount part would pass through) comes in 2 variants, early ones are 3 pieces with separate rubber boots and late ones have the rubber boots moulded or bonded to it. It is possible to fit the HP modified piece through a late one, but it’s difficult and feels like the boot could tear if you are particularly ham fisted. Just an FYI!
