M2 Competition Engine Tuning
I started this thread to stir up interest in the tuning community for the M2C. Even though in theory M3/M4 tuning should work fine with the S55 in the M2C. It would be nice to see some tunes designed for our cars. Flash tunes may have some small differences. I'm looking forward to a M2C to CS tune.

Me too.
Also because us Euros have the OPF issue. And the rest of the S55 threads is 9 out of 10 times about US based tuning companies imo. Cheers Robin |

I'd be more than happy to tune some M2C ( s55 ) on bm3 or MHD. Given that I own a M2 myself I know how these owners wish their car to drive.
Unlike the brute force nature of most S55 tunes on M3/M4.

Now, I have proper throttle tables, different spool characteristics of the car, and I've limited torque a bit in lower RPM's as I prefer a more linear feel. Timing is also adjusted for my particular fuel in my area ( ACN91 ) Overall I feel a more consistent map for my tastes. OP: I have all the files for the M2 S55 including the ones with OPF in the EU market. Will spend time digging more into them soon. There's also been a new rom release for S55 as of 2018 08.

Yesterday I drove a friend's f80 M3 running BM3 with a full e85 tune. His car is DCT.
In comparison to my 6 speed M2 running the BM3 stage 2 e30 map, it is SCARY fast! The torque delivery is so instant which I loved, but it's also extremely brutal on the e85 map. I honestly think it's too much power. Can't believe I'm saying that. M2C with stage one is probably a far more sensible choice. I also found his exhaust too loud in Sport+. It just had dump pipes and a single mid pipe conversion, similar to the AA one. |

There's an OTS map for 30% ethanol. Makes another 15hp or so above the normal stage 2 OTS map. It's great! Although in colder temps you will hit the limit of the hpfp.
I'm running the usual stage 2 mods. DP, Wagner IC and CP |

https://www.willtheyfit.com/index.ph...=10&offset2=40 I want to go up in tire size but I don't want to mess with the dynamics too much otherwise I'm now looking at coil-overs to adjust ride height. I hoped to avoid buying them for awhile until I get a feel for what I think the car needs for my driving style and preference. Thoughts? |

Just came across this on the ESS Tuning website for the S55 platform. I think what they claim in regards to aftermarket exhausts and intakes is VERY interesting. If what they claim is true, I would think a lot of folks have been taken for a ride. I'm not speaking from a position claiming that I know anything whatsoever so I'm just throwing it out there to see what other members think of this.
From their website: *This software is designed to run with OEM S55 air induction system. We have found this overall superior to anything else we have tested on the market. OEM airboxes have virtually 0 restriction and replacing them during our in house testing with an open CAI air intake setup with matched intake funnels yielded absolutely no results at all. We know several companies claim otherwise, but we have not been able to find any advantages to replacing the stock S55 airboxes. Several aftermarket intakes we have seen create MAF turbulence issues and engine operation problems. **Most aftermarket exhaust systems we have tested on the S55 platform produces less power than the OEM exhaust, the only exhaust we have found to match the OEM in power delivery is Akrapovic. |

Also, no one that I'm aware of buys exhausts solely for the claimed 5-10 hp increase. They get them because they desire a change in sound. The "free flow" talk is just marketing as far as I'm concerned. The only real components that are super restrictive on an OEM exhaust are the cats. Any claims of power from just a catback or axelback are BS in my eyes. Unless you're removing a cat, you're spending your money on sound. Yeah, you can get some weight reduction too maybe, but only if you spend a fortune on titanium or get something without mufflers. All that being said, I think exhausts are worth the money if they sound good/drop weight. Don't see a need to claim power. Maybe it's just a sales tactic the industry can't let go of. As for intakes...imo they're a total waste of money. I don't even change the stock filter to a thinner drop in. Is it wrong to sell or buy intakes/exhausts for these cars? Absolutely not. Is it dishonest to market them as power adders? That's personal opinion. |
