my question clearly implies that i know at least that much..... i was just curious. i dont assume i know everything, and i dont close my mind off from empirical data. vehemently denying bm3 could be a culprit is laughable.. its a major variable. as any tune is.. let me just pretend all these posts that say "my engine blew, i was running bm3" dont exist im not writing them.. ive simply said "hey ive noticed a pattern." and then offered up more than one hypothesis as to why it may be and what i think |

I didn't have bm3, but a Dinan piggy when my engine went. Unknowingly, I gapped my plugs down to what the bm3 guys used when I performed spark plug maintenance. It went boom afterwards. I don't know if that was the culprit for sure, but something eats me up just thinking about it. |

Also, Socrates was the most enlightened man in Athens, and they made that fucker drink hemlock all bc he made all the leaders look like fools by simply asking introspective questions. so the root of your annoyance is engrained in your dna, as it is with most of the population Furthermore, u know the bm3 guys on a first name basis, so that deems you bias and your opinion suspect LET ME REITERATE: i am trying to group incidences together. probability&statistics come from a real place, just like stereotypes. Might not always be 100% accurate but more often than not, they are. and i am doing it out of the love for this motor and would like to help people out if they are trying to find pertinent info |

FIRST OFF- that sucks your engine blew up! and ive heard of dinan being on a blown motor too. like twice, u were prob 1.. not as common, BUT you just had to throw in that you copied a BM3 protocol didn't you?! lol. I finally got time to watch the video.. very interesting stuff. a great share. thank you i did mention in my original post that guys with no tunes and a blown motor admitted abusing it, driving it hot, etc and i do know that the downpipes run close to rear cylinders(or crossbank for cyl 5&6.. when one jumps its usually a cylinder near the 'back' of the motor near DP's (correct me where im wrong) and seems like i always see or hear of cyl 5 or 6 blowing out. so a hot spot from dp perhaps, or hot spot in cyl created from running it hard and hot will cause an ignition during compression stroke, and whenever, yea sounds very detrimental MORAL OF STORY: keep the baby cool. I do know bmw def wants This motor to stay cool because it has a very good cooling system and US spec cars get something called 'hot climate pkg' (somebody tell us what exactly extra we get for cooling purposes with that) i wont even drive in weather over 80°F i love it so much(borderline unhealthy lol) i was gonna go Dinan at first, but thanks to this forum i found true unbiased info about it and i Decided I didn't want a piggyback tune bc that simply 'tricks' the ecu and I really didn't like that because my previous dinantune on a previous car was a flash. it was awesome, and i also didnt want to run wires and plugs. it looked like a PITAS. more and more everyday im thinking about just getting cold start and CEL from downpipes coded out and just leaving the ecu stock bc id rather have this thing 4 years at 600hp than 800hp for 4 months but my plan is to keep it forever or until its very outdated if it never becomes sought after. so i probly should leave it stock. |

No, the moral of story should be: Don't correlate forum posts to derive an exaggerated claim. There is no basis to single out bm3 and link that tune to blown motors, when in reality these engines are blowing all over the place.

Because BM3 is so affordable it can be a first choice for many people. This increases the number of BM3 cars on the road compared to other tunes.
Imagine dinan was affordable like BM3, everybody would go for that. Then we would see many dinan cars going bang. The engines are only really safe at stage 1, any more and you're running the risk of rods bending etc due to higher torque output, this doesn't mean the engine can't handle it, just increases risks. Keeping torque down in the tunes will reduce the risks. I'm sure the higher power OTS maps available, are made for people that plan on running alongside forged internals etc. Its down to the user to decide whether they have the supporting mods to make it reliable. |

Exactly this, Stage 1 and sensible maintenance and empathy towards the engine when cold should mean the car is reliable for many years

No tune on mine and never has been.My take on this as OneExtra suggests is getting the engine up to normal oil temp sensibly and is imperative to long engine life.High outside ambient temperatures and constant full boost operation can test your oil to the maximum and certainly the higher the tune means more common sense should be taken when 'gunning it'. Full throttle in manual mode when moving in low gear is a definite no and should never be used. There are also the types, makes and grades of oils used and it's suitability in different climates which has been discussed here exhaustively, just use the one recommended by BMW in your country with the correct specifications.

1. Any tool that allows you to adjust beyond the limits of the engine is a risk.
2. Any "tuner" creating a tune without comprehending knock, boost levels, SPI, engine warmup,mechanical limits and other factors is a risk to customers and their engines. My suggestions 1. Use reputable tuners 2. Get a custom tune specifically for your car 3. Allow your engine to adapt before going WOT with a tune 4. Allow vehicle to fully warmup before going WOT 5. Use SN+ oil to reduce the likely hood of SPI 6. Gap plugs correctly 7. Use good fuel brands What the concensus should form on this forum is the safe power level is for the stock internals and anything higher should require hardware changes (which tuners should be notifying customers of this information, imo). |
