I've been sitting in the weeds reading about the ECU flashes and what is happening to the cars. I'm wondering what it is that the update should do.
I in my previous life was a computer programmer. (I now own a motorcycle shop) Motocycles have been my life and the programming was how I afforded it.
Anyway the programmer in me says to sit tight and see what the flash will do for the car and (sorry about this) let someone else be the guinea pig.
Program updates are not always perfect and this is probably why there are additional updates. I'm thinking they are using us as a beta test and not telling us.
Obviously the car being so new and the drive by wire system just as new makes it hard to get all of the bugs out of the software before they wanted to deliver the cars. I'm ok with that as long as the ECU flash has had proper testing and it won't screw something up or hurt anyone. Also, (just me being paranoid) I think they should share more about what "exactly" the flash is supposed to do for the car. Also, why the third flash already?
