Tunes: can BMW detect them including piggies
I'm not making any claims of certainty or citing specific instances of warranty denial as a result of a tune, rather I'm showing an example of the kind of data available to manufacturers these days—draw your own conclusions. Empirical, anecdotal, inference... they're all fair game for warranty denial. Here's an example of the latter (these are codes thrown by my M8):

This is cool info Limey, I wonder about the inputs and logic of these codes? Could be internal accelerometer or wheel speed sensor logic or some other interesting combination of parameters.

Since I don't check fault codes daily, I reviewed the history and this same code was thrown 2 days earlier. Beyond that, I've never seen this before. My car's SW revisions are unchanged (no OTA updates either). |

Agreed. I landed on accelerometer, too. Wheel rotation alone would be thrown off by wheel spin—imagine on ice. Depending on distance traveled, GPS would be a reasonable input... combine them, well.

I can see how one can drive faster than then the posted speed limit, drive through a red light etc., but how can one exceed the acceleration limit? It’s not like we have the ability to ask for output exceeding 100%? Isn’t the car & engine management that either lets you or doesn’t let you accelerate? Is the user “exceeding the acceleration limit” when he asks for 100% throttle? (Or is the example shown a result of coding & upgrades? |

interesting. P-Codes can normally be cleared. Wonder if this is the case with the above list.

I'd assume so, too, but I've never had it confirmed. They didn't trigger a CEL anyway so kinda moot for the most part.
