heinzboehmer's 2002 Topaz 6MT Coupe

[rtrules]

Also wanted to give feedback regarding your firewall plug, a friend of mine and me both printed and installed it in our cars. It definitely improves the sound of the airbox, so that's a super cool mod. +1 on amazing print quality with pet-cf and 1.2kg saved :-)
Did you also scan the original cabin air filter housing? Would be another way to save some weight.

Turns out the painter who's gonna paint these parts is on vacation until next week. No big deal, but the final beauty shots are slightly delayed.

IDK what you are talking about this whole project is full of beauty shots.

If I do want to pull up a map, I just use my phone on a mount up on the dash. I printed this thing and really like where it puts the screen:

Any pics of this mount w/o the phone? This is on my list, not sure what i want to use.

Very cool, I'm very curious to hear what the answer is with regards to the base 10/16 thing - that's weird!

Yeah it's bizarre. I need to go look at the actual IBus command being sent to double check that I'm using the library correctly, but it seems fine after a quick glance through the code.

Experienced a bit of tunnel vision with base16 thing yesterday, but now that I think about it, the behavior as a whole of this feature is not at all what I expected. This is meant to be implemented as a "X m/ft remaining until next turn" thing, so I would have expected the cluster to scale the data in the incoming command by 10 (or maybe even 100), to save on message length. Not entirely sure in what situation "turn left in 3m" would be useful...

Also, the fact that it does the weird base16 thing and maxes out at uint8 means that it only displays up to 165. Again, when would numbers that small be useful?

I did have to code the cluster with NCS to have it react to the commands, so maybe there's some scaling option I missed that I can use to my advantage. Ooor maybe there's some flags hidden in the upper bits. We'll see.

That's a cool find.I always wanted to retrofit a oil pressure gauge to my car, and I think the integration in the business CD would be perfect regarding placement to see it at a glance. Not sure if it makes sense with refresh rate though.

Yeah, refresh rate on K bus would not be great. You can do CAN (and even analog) with something like Gauge.S, which might be a better platform for it.

Nice! That's awesome to hear.

I do have a scan of the cabin air filter housing, but I did not recreate that piece in CAD. I used the scan as a reference to base the design of my modified filter housing on.

Here's the scan if you want to use it for anything: https://cad.onshape.com/documents/7e...fe3bf8e81c64d2

(link should take you directly to it, but if it doesn't, it's "E46 Cabin Air Filter Housing" inside the "References" folder)

Ha, fair enough. I do think it's probably worth busting out the DSLR and grabbing some decent pics of the setup, instead of shitty, low light phone pics.

oceansize beat me to it. It isn't really all that pretty, but it's designed to be functional and somewhat easy to print. If I won't be using my phone, I just remove the mount from the vent and throw it in the glovebox. One of my requirements when designing this was that it should be installable/removable in single digit number of seconds.

Miles/kilometers? 10 miles= 16km

Cluster may expected kilometers and show your units (miles)

Huh, that's an interesting theory. Should be easy to test out by swapping units back and forth. Will report back.

Also, nice, managed to finish the two remaining operations without breaking the mill again:



Also, took the unbraced M3 down to the machine shop and I'm very surprised at how much I didn't hate it. I was expecting it to feel almost disgusting in the hands, but not at all. It does feel floppy and there is a very obvious amount of grip missing when driving it hard, but it felt fine.

The loss of rigidity is fairly noticeable during normal driving as well, especially with the amount of extra steering input it needs to handle things like fast sweeping turns on the highway. The amount I usually give it felt like 20% too little.

Also, rather amusingly, I found myself instinctively leaning sideways in my seat to counter the lateral loads I'm used to. I had no idea this was something that I did, but it became very obvious after taking some fast on ramps and finding myself overshooting the lean. Guess my brain was expecting more grip, but the chassis never caught up

All in all, definitely prefer the braced car, but it's comforting to have confirmed that all these changes simply augment that special E46 feel and don't flat out replace it with something else.

It’s wild how much the chassis feel changes. Not having the front bracing makes the car feel like it’s on way softer springs to me. Probably the easiest way I can think of communicating the change. It’s ’pleasant’ to tool around in the stock car but ‘fun’ to tool around in the stiffened car.

[heinzboehmer]

Crazy isn't it?

That's a good comparison. No bracing almost makes the car feel more "relaxed".

You're both making me want to quit finishing my current projects and jump straight to this one haha.

Need you to upload the files for the 3D printed brackets first 😉

Haha seriously though, really trying to wrap up a few things before I embark on this. Can't wait though!

Right, ha.

I'll do that this weekend.

CAD is linked in the doc if you're curious and want to poke around with the design.

My apologies - I somehow managed to completely miss this and thought it was just the files shared in the Google Drive.
