And lets say the ecu did log boost and they would see that it was running 10psi above, they would check the wastegate duty cycle log and see its operating within spec, the jb4 is altering the duty cycle after the ecu sends the command. In this case they would assume the wastegate actuator is faulty or the map sensor is faulty and replace either or both and test from there. It would definitely be a head scratcher for the technician because the jb4 isn't there, he can't blame the owner based on an assumption without any proof. The car ran 10psi higher than it should have, logs say everything was working fine, owner is to blame... i don't think so. |

Some of the crazy stuff I see here is insane. I am a BMW tech, no one is looking at logs to see if you had exceeded a certain acceleration or torque value. No one is looking to see if a boost value was ever exceeded, or if ignition timing was ever advanced beyond a certain limit. I'm not sure where these conspiracies come from. Can that data be pulled up? Yes but not by a dealership, you'd have to have an insane claim or be acting pretty shady for any of that to be looked into. There are certainly cases where you will be automatically flagged from flash tunes when data is transmitted via ISTA to BMW but realistically if you're just using a piggy back and you pull it off before going in it's not likely you'll have any issues. Now that's not a guarantee, so don't come at me if you get a claim denied it's all at your own risk. But these crazy ideas that a tech is gonna waste his flat rate time to deny your claim is pretty wild.

They wouldn't see boost was 10psi above since the JB4 connects to and alters the signals for both boost sensors. They'd see boost is at factory levels.

Have they not became “woke” enough in just seeing if someone has tapped into or altered any code or timing/boost level/ Hp tq # etc…?
I know if it were my company I would invest in said approach.. For context: ^^^ says me who is installing JB4 on Tuesday!!! Let’er rip tater chip mindset for sure. |

There are a lot of techs that will void warranty for things like an intake even without a tune. Someone on the F30 forums got his warranty voided because he swapped OEM staggered tires on his xdrive car and they claimed that caused the transfer case to fail. And of course I mentioned my dealer experience above. So you really can't assume that what works for one person works for everyone, or how one dealer handles warranties is how all dealers handle it. They can easily see simple things like rev limit exceeded, maf limits exceeded, etc. that would trigger more investigation. Even a 10-plug piggyback doesen't modify everything. It just depends on who you're working with and how thorough they chose to be. |

Can we make a rule at mod level maybe, to stop talking about the "warranty voided - not voided" subject?
Most threads start talking about something and then end up with pages and pages about this subject, it's always the case and it happens in every forum. Maybe would be better to have a pinned thread for that specific subject and avoid the noise. Now I can't recall the last comment on this thread related to the actual tune. |

It’s rather simple, perceived power thresholds are rather subjective & money will ALWAYS be relative. Not everyone who tunes their car has improper expectations if/when things need attention. |

Personally I have the opposite perspective where I feel like paying a very high price for a vehicle means I should be getting more out of its output capabilities if a tune is available and reasonable. Even though out of the box these are still fantastic motors, it's a limited version of what you should be experiencing for the cost.
