M135i vs M135i LCi
Hey folks,
I just picked a fully loaded 2014 M135i with 9300km on it. I am just very curious what's the difference between the LCi models? I think 6hp bump and 0.1 torque bump. Is there any hardware mechanical difference? I am sure BMW updated the ECU and most likely a few minor tweaks in the ZF 8 speed gear box? Is possible to get the latest software to behave like the latest M135i? Or Is there any 3rd party tuning company can do this? ( it pretty much drove the same as my previous 2015 M235i 8 speed ) Many thanks! |

There's been a few other threads on this, so it might pay just to look or search.

The pre-LCI M135i's had the uprated engines in them (326BHP) for about six months

I dont believe there was any other hardware changes although some people swear the handling is improved on LCI models. BMW deny this however so it may be simply snake oil.
I for one am a happy owner of a 2013 nearly new M135 (8800 miles on clock when i bought mine 2 months ago) |

Two mates dyno'd there cars with a decent outfit; both pre LCI, one just under 340bhp, one just over 340.
Another tuner I know has tested over 20 M135is, all pre LCI; not one has been under 350lbs-ft. They aren't short of poke. |

Searching the limits

For sure it drifts a lot better but its the transition from neutral to oversteer that becomes a lot more controllable. Instead of that sudden transition, which many drivers may not be quick or skilled enough to catch, its simply a matter of taking off some lock as the car gradually and progressively starts to oversteer. For me, its that gentle transition that delivers the biggest payoff |

For most drivers, it makes no sense to install the LSD, because they would never notice the difference anyway. But most drivers don't have an M135i. I remember a suspension engineer at BMW that was asked if the suspension setup on a new BMW was set up for the average driver. He said no! It was set up for the average BMW driver! :-) |

Not really, sorry it's just that I noticed BMW updated the pre-LCI M135i specification not long before I committed to order one and the dealer confirmed the new builds were getting some of the little engine tweaks of the upcoming LCI. Not that 6HP makes a great deal of difference but y'know... I'll take it

It is slightly more common to approach the limit now and then in countries with winter climate. A little bit of sliding around and wheelspin is common to have a feel for how slippery it is. Even if you are going with safe speed with lots of safety margin, you can touch the limit with a quick stomp on the brake or throttle, or a yank in the steering wheel.
