2016 Steering module and software
didn't know which section to post this in.
The LCI and 2016 BMW have improved steering. Haven't got to demo a new car yet, but a few buddies and reviews have already noted improvement and that the LCI has a new steering module and obvious revised software. Forget an engine tune. how much and is this even possible to update a pre LCI car? |

Hmm would be interested to hear this, surely we can get the new software put on our existing steering module

Overall, these improvements have been minor and are not likely enough to sway you if you hated the EPS feel but they are welcome and noticeable. The steering still feels worlds apart from any of my E90-generation cars, but it's at least moving slowly in the right direction. |

I have a loaner 328i 16' model with 18' wheels, while my 14 is being repaired. I can also agree that the steering is somehow BETTER, and now sure quite how. Sport mode simply feels weightier vs the sport in my vehicle. Comfort seems unchanged. It's definitely better, or at least that's my opinion in direct relation to my feather light steering.

I have a 2016 loaner while my 2014 F30 335 xdrive is in for service and I agree the steering does seem better than the 2014. The switch from comfort to sport makes the steering heavier and more precise. I am also interested in if we can transform older F30's to something like the 2016 setup. Anyone?

Not sure about any changes in hardware or part numbers, but people have been reporting improved steering feel after service/software updates in connection with routine maintenance for a year or so now. My service adviser denies that there is any software upgrade that changes steering feel but it seems other SAs have confirmed its out there.

There is supposed to be another software update in the coming months. Hopefully more improvements are on their way relating to steering in that update.
I had a software upgrade a few months ago and do agree it's somewhat better now. It's so subtle but getting to the point of a non issue. Some of that improvement is the weight when you're at speed. i recently got a Cayman and can tell you EPS can be so much better in my BMW. |

Part of the 2016 upgrade was changes in suspension geometry in the front end, so it's not all in the steering rack & software. I don't doubt that they're improving it over time as well though.

Are you guys sure its not mainly tires? Ditching runflats for my tire of choice for the last 10 years makes a huge difference. Dunlop star specs will make a mini van feel great!

but clearly, after test driving the 340i, it confirmed how wobbly and putrid the prev gen steering was. A wobble. Even in Sports +, my steering BARELY tightens. On the 340i it is very close to e90... Stiff, predictable and more hands-to-eye. More artificial? Yes. if there was a 2,000$ option to replace the 335i's, I would!! Too much debate around the issue. Degrees per turn Responsiveness is not the issue: it is the wobble like soft torque settings. At high speeds, when just about every driver tightens his grip on a wheel, the EPS tension is still so low that one over-inputs. On the 340, the tension increases to a point that the torque effort matches the hand tension, turning speed and correction requirements 180 degrees better. The wheel essentially tells you "hey I need X amount of input to take this turn radius at Y speed." On the 335i, the soft wobble that rack is, one wobbles that noodle wheel tension with too much input and is forced to reduce it as understeer kicks in. Over and back. Test dive the 340i, it is the exculpatory Munich solution to what should be a general solution for anyone with a 335 or at least, M Performance setup. |

When you look at part numbers, in particular tension struts, wishbones etc, part numbers are identical throughout the F2x / F3x range with the exception of the M135i / M235i / M140i / M240i. What did change however is the EPS steering rack module. There actually is and it doesn't even cost $2k: change the lower control arms for increased negative camber will give back this steering linearity that you're missing, and significantly correct understeer: https://www.turnermotorsport.com/p-3...-arms/?pdk=AQE Another option is to install the M135i / M235i / M140i / M240i lower control arms, which are designed for the F2x/F3x chassis, I haven't tried myself. Item #10 in below diagram: http://www.etkbmw.com/bmw/EN/search/...CE/31/31_0942/ Next, a struts tower brace is good to make steering more precise and is inexpensive (~$200) and easy to mount yourself. https://www.turnermotorsport.com/p-2...brace-f30-f31/ Then next steps would be to stiffen the anti roll bars - not very expensive parts, but difficult to mount on these chassis.

Or that there isn't an M335i-M340i (yet?) - they're probably afraid this would eat into their M3 customer base...

Hey all. Sorry to revive an old thread but I am very interested in this. I had a similar experience recently where I was given a LCI loaner and the steering was noticeably tighter and more responsive. I drive an x-drive and the loaner was an x-drive as well.
I cant help but think there is some updated steering module that can fix the loose steering of the f30. I always drive in sport mode and there was a noticeable difference in sport mode between the two cars. Has anyone been able to figure this out yet? |

Could be different suspensions? Suspension has a noticeable effect on steering. Even more so with EDC.

Have you heard if a module change can improve the rack responsiveness and wheel feel? |
