I’m going to get the alignment done to match the CS too I think.

I did put a quick video on YouTube too and you can hear the gear changes are quicker on that

Interesting, so doesn't make it twitchy or anyhing? I ask because the CS steering tune is of course dialed to the CS suspension setup which is a bit different from base. Link to youtube video I'd like to see that.

Will you need to get adjustable camber plates? I was thinking of doing that I'm trying to get close to the CS feel, if not better!

Also would you mind linking the video?

I had the gearbox flashed only today. Night and day difference! Would highly recommend this over XHP as it is a stock BMW flash for the same engine and transmission as the CS is, not to mention, much cheaper than XHP.

kubax86 is amazing to work with. Love it so much. Thank you again!

Can get the left and right uprights from the CS if you really wanna commit to getting the perfect camber..

Would you need anything else? Or just these parts? (Strictly speaking of the camber). Obviously the anti-roll bar, damper and springs are different too

I’m glad you decided to take the plunge! Life is better with the CS flash…lol

No it’s not twitchy at all, it’s the same ratio on the steering rack I guess..

The steering just feels sharper and gives more feedback.

As the wheel goes off center you can just feel it load up/give feedback quicker.

The video isn’t anything special, still learning but will be doing more content including my new incoming wheels etc.

If anyone can give us a sub and like it’s appreciated, I hate being on video haha so trying to get over it

I’m not sure yet, need to look into it further.

Are the shock absorbers different then? Or just software?

I've been told the dampers/shocks and springs are different. But I have a suspicion it might just be the M Performance HAS kit installed automatically, rather than something completely new. Which I already optioned on my M4CX. So if that is the case, it's two less things I'd have to do to get the proper suspension set up if I want the suspension tune as well.

I’ve just done the eibach springs on mine, ride pretty much like stock albeit marginally firmer but looks much better.

The camber will have changed slightly, but I’ve not had the alignment done yet as waiting to find the CS settings and see what I need to do to get similar.

Looks gorgeous man! Love the car. I'd send a picture of mine, but it's still sitting at the port in Germany lol.

I'm thinking between getting the CS front anti-roll bar, the camber braces or whatever you wanna call them, and the MP HAS system, I think I'd be extremely close to the CS. Not to mention I wanna do the bushings as well for further enhancements

How does this work when there is an OTA update? We would have to reflash?

Yes, if you get this done you will need to turn off OTA updates as they can update transmission software as well.

That’s the idea.

I asked kubax86 about switching back to stock for dealer servicing and he said that it’s fine but you’d need to contact him to make the switch. I assume the same would be applicable if you switched to XHP and wanted to go back to the CS tune.

Boogie2121 · 07-02-2023, 11:31 AM

Okay I’ll get to 1200 this month and do this. Should be interesting to see the difference as I will be lowered, exhaust, intakes, and jb4 or Racechip.

I’ve got CS software and am running Racechip

hellcat2m4 · 07-02-2023, 12:54 PM

Would anyone want to post a video in D3 MDM doing a WOT pull from 2nd-3rd?

Do you have to wait? Or can you do it from the jump?

Think from the jump but I want to get to break in service first.
