Karter16's Silbergrau E46 M3 Journal

Not sure if you have tried them yet, but the 07119905016 bolts won't work on the Karb airbox.

Dammit no I hadn't - don't know why I had it in my head I'd seen someone else do this. Thanks very much for that - have ordered some suitable hardware. FYI what's needed are M6x16 Torx washer head screws.

Some of the bits of hardware I was waiting on for the airbox install arrived today.

07119905016 - original silver bolts that hold the two pieces of the airbox together. The black ones that come with the Karbonius look great, but I'm wanting to replicate the original CSL look with the silver hardware.

07119901780 - original bolts that attach the snorkel to the airbox. The Haimus Racing snorkel comes with silver through-bolts and nuts, plus insertable collars to go in the 3D-printed mounting holes. I'm not sure whether the Haimus Racing airbox doesn't have threaded mounts on the airbox, but anyway the Karbonius does. I did a quick test fit and confirmed that using the Haimus collars with the OE bolts works.

07119902626 - original bolts for the MAP sensor to secondary air rail. As George Hill noted some time ago these are too short to fit on my MAP sensor adapter, but with them in hand I was able to confirm that these are DIN7984 spec bolts, and have ordered some M6x18mm DIN7984 bolts which will fit perfectly.

Only item (I think) I'm waiting on now is the CSL dipstick tube. I realised I have a bit of a problem when I went downstairs to find something and couldn't even remember what's in all of the boxes of parts on my shelves. Need the Christmas break to come round so that I can get some of this stuff installed!

Well look what arrived yesterday, less than 6 weeks after I ordered it! I saw a few months ago that Karbonius had made another mold for the CSL replica airbox to speed up production and certainly would seem to have helped!

Can't really say anything about this piece that hasn't already been said. It's spectacularly good. The memory of the cost simply melts away when you hold it in your hand and look at it.

I'm still waiting on the CSL dipstick tube plus a few minor pieces of hardware, but hopeful of having everything by the time the Christmas break rolls around!

In the meantime all these parts continue to clutter up my spare room!

It appears you are correct. I checked back in my excel files and indeed they do look the same. Not sure where I got that from..

KF_TIENDE_N_RF are different between euro and CSL tunes that I’m looking at.

Interesting - so the original binary from my car is 211323001901JD54 (appears to be an unlisted variant in the Comprehensive MSS54/MSS54HP DME Information thread) and KF_TIENDE_N_RF is the same as for the 0401PD31 binary.


1901JD54


0401PD31 (CSL)

I'm curious - aside from KF_TI_N_RF (which I missed out of the list in my post above) the only other Injection/Ignition tables I see differences in are in the warm-up/cat heating/secondary air pump tables for calculating the warm up factors (which I'll not bother with for now).

I do note that in the US map KF_RF_N_AQ_REL and KF_TIENDE_N_RF differ to the CSL map, however these two are the same between my Euro tune and the CSL tune.

Or I'm missing something 😅

I didn’t modify KF_RF_N_AQ_REL and KF_TIENDE_N_RF are different between euro and CSL tunes that I’m looking at. Just a couple notes

[karter16]

I'll let you walk your way there!

In addition, my euro mullet ended up with several little custom changes in the end, rather than pulling straight from euro maps (US fuel likely cause). It'll be more rewarding for you to chase it yourself I think.

For sure, ya don't give me the answers! - I'll keep posting here with updates as I work stuff out. Writing things out helps me spot where I'm doing dumb things!

There are a few extra tables that needed dialing in for me but that may be in part because the US fuels are different.

Hey - the CSL rail part is now, I believe, ready to go. I haven't published the CAD file yet as a bit reluctant to put it out there without having proven it first (I've test fitted it and all seems well, but haven't proven it in operation yet). If you're keen to give it a go let me know and I can send you the CAD file :-)

sweet! i’m in no rush at the moment to install the csl intake so i’ll wait to hear your results with them first to see if you decide to make any improvements or revisions. really excited to see the results and the iterating work with the tune

[karter16]

always love the updates, what's happening with the csl rail part by the way?

Happy iterating! Once you're in the weeds, keep posting your notes here regarding where it works well and where it doesn't. There are a few extra tables that needed dialing in for me but that may be in part because the US fuels are different.

Thanks! I'm looking forward to it! Yes will definitely keep this updated with how I go - just need the rest of the parts to arrive now!
