I got new info on this..
As per the M tech at a very good dealership.. he stated in his recent classes he was informed that BMW will now download all diagnostics on 2017+ M cars. Before, this info was sent only under big case work, but now it will be done as standard for even a filter change. He stated the cars will have sensors in the transmission and differential that measure torque load. If either registers more than stock output, it will flag the check engine light. This wont necessarily void warranty, but the info will be sent to BMW on your dealer visit automatically, they cant control it, and BMW then can deny future claims of parts that are flagged in the computer memory. Im assuming tuners will find a way around this, but BMW is cracking down mainly because of all the increased costs associated with warranty claims done on abused vehicles. Sucks for all of us..

If that is the case just check for fault codes prior to your visit and clear them. Can be easily done with Rheingold and an ENET cable. Software is free and cable is $15 on Amazon.

Interesting thread. I guess as most performance motors move to turbo, the ability to tune increases and the need to protect against warranty claims increases. Shame BMW don't offer upgrades themselves. Also interested why some tuners claim more power for the same conversion for CP cars as I thought this was just a map change ?

So just reading through this thread. I purchased my M5 in late Sept (14 CP). Day 2 of ownership the engine had a catostrophic failure, rod blew through the engine block. The car was babied by the previous owner. 1.) These engines are NOT bullet proof. 2.) BMW NA approved the replacement of the engine without any data upload. In fact my vehicle has been experiencing electronic issues over the last two months and has been at the dealership for 80% of that time. BMW local field tech is involved. It was confirmed that over the last two months no data has been uploaded.
I think the whole uploading data thing is rare in my opinion. Maybe it's dealer specific. Thoughts? |

how do u know the car was babied? did he tell you this, do you have proof? how do you know bmw NA didn't pull info from the car? I find it hard to believe bmw would spend god knows how much to replace a motor in an m5/m6 without doing their homework. Not saying the car is tuned etc, BUT, they still need to know WHY such a failure occurred. |

No engine line is bullet proof, you will always have a range of failures, just some engines and marques are better than others and we are lucky with the S63tu and a good track record even when pushing up to near double the standard rated output.

I know the data was never shared through a number of means.
1.) I was at the dealership all morning after i dropped it off. All they asked for was photos of the hole in the block. 2.) The local BMW NA field tech walked me through their internal vehicle management tool which contains all interactions between my vehicle and BMW NA. Last upload was a year back. I met the person who owned the car before me. A 72 year old guy who traded it in as he was afraid of the amount of power it produced. His feedback was, they saw a wealth guy come in and sold him more than he needed. Traded it in for a 535. Now don't get me wrong, I'm sure he floored it a couple times, but no where near any enthusiast. |

I only use 91, are you saying certain brands like shell or chevron?

93-Octane is safe for a 22psi tune unless there is significant timing advance. All depends how the tuner makes the file.

I don't understand your comment.
Octane requirements do decrease with altitude but if you are boosting 22psi+ on 91-octane you have no insurance against a catastrophic event and are relying on the DME's knock sensors which are good but they work by actually detecting knock. |
