Did a quick statistical breakdown of the poll as it stands a few nights ago but posted it in another thread. Adding it here to share with everyone who is concerned about this.
“I took the poll that was done a while back and just did simple statistics to see what the fail rate was: I was going to play with the numbers a little more but that's ok, I'm open to sharing this with anyone who reads it. Because of the smaller sample size of tuned cars, I didn't split between DCT/Manual or year to get a general sense of the weight of the numbers. Stock: 3% failure rate (out of 555 cars) 450-500whp tune: 11% (out of 227 cars) 500-550whp tunes: 19% (out of 149 cars) 550+ whp tunes: 33% (out of 90 cars) If you focus on just manual vs. dct (tuned cars only), Manual: 22% fail rate (out of 146 cars) DCT: 18% fail rate (out of 320 cars) Takeaway: if you do a light tune, you'd be silly not put on a CBC, or as Clint would say "You feeling lucky today?" Assuming the cost of a motor is 15-20K, if you're going to light tune, you need at the minimum, a budget of $1- 1.5k (based on the general probability of failure, so a CBC is probably a good way to go about it. papasmurf_m3 had some good points. If you follow folks like Apex Ring Taxi, they haven’t had SCH failures on their M4 ring taxis and were wondering why it was happening to M3/M4 owners. It’s clearly driving behavior. That has a sizeable component to it. So: Don’t floor it when you are in high gear and low rpm and I would add, stay in S2, until you put a fix in. The Ring guys are almost always in middle to high gears with high rpm all day long. |

Really? That's a good data point. Robert Mitchell didn't mention it in a recent video on Misha's channel.
Here's what he said: A viewer commented: After watching the video, I still have a question, I don't know if it will get answered. I know this S55 engines have the crank hub issue, and when I watch Misha's videos and see the M3 and M4 I always wonder how this cars can keep up with all the laps without having a failure on the crank hub. Most of the M3s and M4s are usually used in the street with some track use along their life, but not always in track. I know that the crank hub issue normally happens to cars that are tuned, but also on stock cars. Any info about this? Robert Mitchell I can say that w all of our S55 cars we have had no hub issue... so its sort of a mystery to me that everyone is doin this ''fix'' and we've not seen the other end of what needs to be fixed lol |

I am really torn between getting a CBC or full fix. I am at good power (no E85 though), 6MT, and I don't do burnouts, floor it at low RPM, etc. But still conerned!

How many people here have had SCH issues with ONLY DINAN parts/tunes?
Also, the only other thing that all of you report on inconsistently is HOW you drive your cars. My 2018 ZCP currently has a DINAN Stage 1 and makes 461-whp and no SCH. I have never done a burnout, doughnut, launch, drift or a 0-60 test. I do kickdowns once in a while and sometimes drive in S3. I already know a lot of you will say I'm not enjoying the full potential of my car, but we all enjoy our cars in different ways. If we ALL still don't know why some of these cars do experience SCH and some do not, then we can be forgiven for thinking it might be related to something else, like how we are driving our cars. Perhaps we should do another poll that attempts to draw a correlation between aggressive driving behavior and a SCH. |

Way too many polling options. Think no spun hub is misleading because 1) you don't get everyone to vote so it's kind of meaningless, 2) you can't change your vote. I accidentally clicked and voted on my phone and can't change it. I don't even know which one I clicked.

Great Initiative
I Appreciate this thread, not perfect but the data collected is very useful. Even if the participating numbers is not enough , i have gotten an insight as to the percentage of No SCH vs failure base on the numbers who participated.

Current Data
I ran some aggregated data for a few minutes. I feel like this is the most applicable, since a majority of us seem to be tuned.
Utilizing data as of 3/9/2021 Out 500-550whp cars, 30 have failed, and 127 have not spun. 19.1% failure rate Our of 450-500whp cars, 33 have failed, and 212 have not spun. 13.5% failure rate. Aggregated, 63 failures vs. 339 cars that have not spun. 15.7% failure rate. I'm taking it with a grain of salt since we have a low population sample

I'm about to have a bunch of bolt-on Dinan parts and possibly a tune - whether it's Dinan or bootmod and can report but I don't drive like an idiot, don't do burnouts or street racing so I don't think I will end up on the crank hub casualty list.

I'm certainly not denying its an issue, but it seems like we have some relative knowledge on how to protect it ie. no use of kickdown, or money shifts, etc. If total numbers were higher than a small percentage on stock engines, I feel like BMW would have had to issue a fix or a recall no?
