Karter16's Silbergrau E46 M3 Journal

Such a great thread! Keep it up!

[karter16]

one of the first things I printed was your CSL SMG Reservoir Bracket using PET-CF. The bracket is such a great solution!

Haha I'm glad someone else appreciates it - it was an absolute nightmare to get right, I went through far too many revisions to get it positioning the reservoir just right. Anyway, stoked to hear you're using it!!

I'm keen to see how you go with the snorkel. I've kind of been keen to create a reproduction of the OE snorkel with the flap. The potentiometer and motor are both available as separate parts, so it doesn't seem outside the realms of plausibility to create a complete reproduction. I don't really have any need for it is the thing so hasn't been that far up the priority list. (Also would need an H-series to print it )

Got a new toy today - Printy The Printer (named by my 9 year old)

Nice, I picked up a H2D a few months ago and one of the first things I printed was your CSL SMG Reservoir Bracket using PET-CF. The bracket is such a great solution!

I have tried to clean up the scans that heinzboehmer shared of the Karbonius snorkel because I would love to print one, but I simply keep running out of talent. CAD is hard and feels so counterintuitive. I am not sure what will break first: my will to get the scans cleaned up or my resolve to simply not order a Karbonius snorkel.

Awesome! X2D?

Yep! decided it was the best price/feature combo for my main use cases. Don't really have any need/desire to do multiple colours of anything at once, but dedicated nozzle for support material will be extremely useful.

Crazy how far they've come since the MendelMax 1.5 I built in 2012!

Haven't made any changes to the SMG code (other than flashing the "255" tune to match the CSL DME). I don't think there's anything wrong with the SMG code so to speak, more just about giving it the predictable engine response it's expecting.

Thanks, that makes perfect sense to me. I had misunderstood "Nailing filling (RF) in the tune so that the engine is responding as the SMG model expects: 50%" was changes to the SMG code itself.

While I have seemingly been in the minority in loving the SMG, I am very happy with the Mullet Tune along with the CSL "255" SMG code.

With this combo I would never consider a manual swap, and when I finally pull the trigger on a coupe I am happy to know that having SMG is mostly seen as a bad thing in terms of resale desirability!

Just curious

Are you modifying the SMG code based on the CSL 255 tune?

Something else I forgot to mention is how delightful the SMG is now, particularly in terms of downshifts and rev matching. From all the different things I've done I think the proportion of improvement in this regard is approximately as follows:

SMG relearning/adaptions: 20%
New rear diff bushes + RACP reinforcement: 30% (I did these two things together so can't rate them separately)
Nailing filling (RF) in the tune so that the engine is responding as the SMG model expects: 50%

Me from a few years ago would never have dared doing something like coming to a stop with foot completely off accelerator downshifting from 2nd to 1st. Now I do it pretty much without even thinking - it's smooth, accurate and reliable. Good fun.

That is amazing news. Would love to do it as soon as I get a chance LOL.

If I’d s54ed this car myself it would probably have an SMG in it! I’m not surprised how much better it is.

Cab bar is 27 vs 26mm, so a ~16% increase. The sway bar contributes more to roll stiffness in the front than the springs too, so it’s not a small change. Maybe 10% total. And you increased your front tire width by, what, 10%?

Yep spot on! Awesome thanks heaps!

Back from my weekend away - car was flawless. I'm super happy with where the tune is at, got a really good mix of driving conditions and loads and don't have any complaints of note. Since dialling in the tune something I've noticed is how when I'm just cruising I'm generally sitting at lower RPM than I would have pre-CSL intake. I suspect there must have been something non-optimal with my MAF setup, because the CSL setup is actually better in my case.

Easy - cabrio front sway bar

..if you're still on stock bars, that is

Yep still on stock bars - how much stiffer is the cabriolet front bar do you know/think? It feels like I need a decent bit more stiffness?

And reinforce the sway bar mount

Yes absolutely! this would be the first thing for sure. I'm lining up to do Heinz's E86 front strut reinforcement and Bryson's fender reinforcement both of which need epoxy bonding, so would do the sway bar mounts at the same time for maximum efficiency!
