Software differences between Base and Competition
Hi folks,
I apologize if this has been asked and answered before, but I really curious what are the software differences between Base and Competition trims. I know the Competition has more HP and way more TQ, but what else is different? In particular, I am curious to know if the coding for braking, suspension, e-Diff, throttle mapping is also different. To give you an idea why I am asking this: I spent a lot of time tuning my E90 335i,not only the engine management but also all of the modules that are responsible for the chassis. A lot of the controllers in the E90 are shared between the 328, 335 and the M3 and the difference is the firmware and coding. Can someone confirm the differences between G80 Base and Competition models when it comes to controller firmware and coding? Thanks in advance

Curious if there is any difference. I would have guessed that if it were not for the "base" being a manual, they'd be 100% identical.

Nothing else. Just higher PSI from 10.x to 14.x to gain the extra 30 HP. For that you lose 6MT but get “competition” moniker and automatic ZF tranny that’s in every other BMW and other manufacturers

Why wouldn't they call the 503/8ZF the competition version? Its quicker than the 473/6MT both on the drag strip & track day.
The 6MT is the "fun nostalgia" version but as the quick winning competition car, that ended for the manual transmission in the 1960/1970's Muscle Car Era.

You get a different flash by 4 bars higher and a blacked out badge - that’s it. There’s nothing competition about AT. All wheel drive is a different story but there’s no 6MT all wheel drive so we will never know. This isn’t a regular 911 vs GT3 story no matter how much you squint lol |

Well, FWIW, in the previous generation M3/M4 (F8x), there were differences in chassis firmware for steering, differential, traction control (aka MDM mode), suspension (for EDC cars), and transmission (for DCT cars) between different models/packages. Specifically, the M4 GTS, M4 CS, M3 CS, M3/M4 Competition, and Base M3/M4 (aka the "Civic M3/M4") all had different firmware in those respective modules (although some variants shared the same firmware on some modules, but different firmware in others - it was a mixed bag of sorts). In fact, there were some hardware differences as well between the different variants such as sway bars and springs.
Once the F8x matured some (and was "cracked" so to speak), it was (and still is) popular to update the various modules I mentioned above to the M3/M4 CS and/or M4 GTS chassis firmware for improved performance. I did this as well with my F80 M3 (Competition), upgrading to all of the M3 CS firmware stuff, which made a noticeable performance improvement, especially for the EDC suspension. As far as the G8x is concerned, I would be surprised if there weren't similar firmware differences in both the chassis modules and some of the hardware (like springs and sway bars) between the different G8x variants. I think it is a foregone conclusion that the M4 CSL will have different chassis firmware and hardware. But it makes sense that there could also be some firmware and/or hardware differences between the M3/M4, M3/M4 Comp, and M3/M4 xDrive as well. Time will tell as the G8x is eventually fully "cracked" just like the previous generations….

Interesting! I started a thread about it here as I saw a few 6MTs with them. They will be standard from MY23 on but seems like a few earlier ones had them fitted. I'll guess it came down to availability.
Oh well. At least mine came with Michelins. |
