I think we are missing some key information here that the OP wont share pertaining to the events immediately preceding the catastrophic failure.
...the 50% off the engine was via the selling/servicing dealer. BMW washed their hands of the whole event. |

It was out of warranty, they didn't have to cover any of it. 50% is a gift to the OP by the dealer, not BMW.

I hate to say it, but...those pictures look VERY familiar! My engine chunks were a bit different though, I guess like fingerprints, no 2 engines break alike.
Nice to see you're on your way to getting back on the road soon. Mine took about 3 full days after the point you're at... |

Get pictures of the combustion chambers valve and piston side as well as the plugs on all cylinders.

at least one smart person on here: http://www.m3post.com/forums/showthread.php?t=280965 Anyone who doesn't believe me, feel free to run 87 in your M3. Nothing bad will happen if you run it tank after tank. Really.. *snicker* Correction, run 87, and deleted cats, headers, and straight pipe exhaust. Doesn't matter, looks like you're about to get schooled anyway, they're working on BMW's.. here come lots and lots of datalogs and user tunes. Knew I should have taken the job with these guys: http://cobbtuning.com/products/?id=5833 http://www.accessecu.com/accessport/...AccessPORT.pdf "Adjusted boost levels, fuel, ignition timing".... different maps targeting 91 and 93 octane... Serious frickin right here. The data says I'm right. Good timing Cobb. Also, just to rub it in a little more "BMW ECU are super awesome and do calculations at 1 jigawatt and fairies know what the right timing is" http://www.cobbforums.com/forums/sho...libration-Team Is that a timing map? oh noes!!!

-Travis @ Cobb This is an N54, not the S65 - first of all, and NA tuning is not FI tuning. Even still, the programing was able to adjust even when increasing the power output of the car, which we are not doing here (just changing exhaust and letting it adapt). I fail to see how this supports any of your arguments although, truth be told, I'm having difficulty following you at this point. The S65 stock tuning can adapt safely to an exhaust - you don't know what you are talking about. |

You guys are . Even in the facts you don't back down. Not uncommon but seriously gives me the The fact that you don't understand why an argument about running 87 is relevant to timing changes related to changing exhaust configuration is valid should be a clue to you.
Let's try a different highlighting strategy. Quote:
S65 doing timing correct for exhaust poses the same dangers as above. The physics are the same. There is no pixie dust in the S65 ECU that makes it work better. The base timing map after changing exhaust parts will not change and will be suboptimal requiring timing corrections which were designed to cope with fuel quality and manufacturing tolerances, and _not_ redneck engineering.

You are comparing running a fuel outside of the manuf specs in the engine. The car will perform horribly, the engine will suffer some level of damage, and will dyno way down on power. Tell me how the "physics are the same" between that and the ECU adjusting fuel and timing, and probably some other things, for an exhaust that will improve the VE of the engine and result in more HP on the dyno? Makes no sense. Explain this to me, how do people make more power on the dyno with constant detonation and timing being pulled? Why do tuners, who run the stock car on the dyno for a baseline, NEVER report what you are talking about? Seems like it would be an awesome way to sell their software. How can BMW sell their own exhaust which has been shown to make power on the dyno? Your argument makes no sense. Also, "adjustments to the base map" are always needed regardless of aftermarket parts. That's why they call it a base map. If everything worked the same on every car in every environment, they would just call it "the map". By your logic - you better not change your fuel quality, drive at different altitudes, or in different ambient temperatures in your car. |

This is even funnier. You are totally misreading Travis' statement. Here, let's do this a third time:
"As I increased the amount of Load requested to begin raising horsepower, it became obvious that the factory timing table was a bit too aggressive, especially at higher loads. The ECU properly addressed it via timing correction on the noisy cylinder(s), but relying on a prompt response from the ECU during knock events is a dangerous tuning strategy." So he was actually requesting more power from the engine and found that, at those higher load values, the timing was too aggressive. He was tuning the software. Luckily, aftermarket exhausts do not reflash this ECU to request more power from the engine. |

Look, I get it, you tuned a Subaru and read Maximum Boost, and now you are on another level. So do you go around to all web boards and tell them that exhaust modifications will blow their engines, or are we just fortunate? Please CC me on your letter to BMW warning them that their aftermarket exhausts are putting their engines in danger. Thanks. |

Wondering what happened to your M3. I have 08M3 as well with 14k miles on her. I have some cosmetic mods but my car is purely stock from mechanical stand point. 3 weeks ago, my engine blew up while cruising at 70 mph on a highway. The service center was trying to blame it on me saying it's due to over-revving and say I need a new engine and it won't be covered under warranty. I ensured them I never over-revved the car or mis-shifted. They decided open up the engine. After diagnosis on the opened up engine, they changed their mind and they are working on getting new engine installed on my M3. Now I just found out that the engine they are installing is a refurbished engine.
I'm wondering if the service center has done the same for you. Also does anyone know if the refurbished engine are rebuilt by BMW? I'm just so pissed at how BMW is handling all this. |

Lol @ this Dexx kid, What a troll. I think we've all met people like him, The stubborn kid in class who never thinks hes wrong, argues with the professor despite his own lack of education. You will never convince him hes wrong. He just enjoys having a controversial perspective, and letting everyone known exactly what he thinks.

Rod completely snapped... another one bites the dust.
Sorry to hear of your misfortune on this OP. Did they say anything about the condition of the bearings? That would put alot of people's minds at ease. This is not the first, second... or 6th time I have seen a snapped rod where the bearings were completely fine. As for the exhaust s ignition timing arguement going on - please someone find the stock ignition map for WOT I have posted so many times on this forum. Will shut up the arguing when it seen the radical ignition targets the factory software runs. |
