Thanks for your comprehensive reply Christian. When manufacturer's indeed do write dangerous firmware, no pedestrian will be safe on the streets anymore. Especially when cars drive without human intervention and kill people already. Even if the car's firmware works flawlessly, still the sensors made by other firms can be defective. And yesterday another scandall about electronic sensors was revealed on Dutch tv. It was about farmers who were forced to install expensive aircleaning systems in their pigfarms. And after recent inspection by the authorities it was a stated fact that almost none of the aircleaner installations worked because of bad sensors or work done by unqualified workmen. Also by false regulations that made possible that anyone even without qualifications could install those aircleaner installations.

Hi!
Thank you for supporting my articles.
A very good concept of writing in your comment. 😉

So, the thinks are these:
We have to learn several relations when we talk about programming an ecu or bsi or abs ecu etc.

1. we almost never do a firmware update, there is not need, especial on a really high ranked car maker.
2. the car makers never make his own electronics, so in my VW Polo is an Italian electronic system. The maker of the electronics in my are is Magneti Marelli.

2. The dealers and repairers are talking and mixing up thinks.
They always talk about "firmware upgrade" but in real situation that is the MAP update in the ecu.
A MAP update has nothing to do with firmware update.
The firmware controls the hardware based of the setup parameters in the MAP files of the flash ic.

Any parametric changes made in the car are changes in the flesh ic.
- torque
- speed limitation
- immobilizer infos
- egr, O2 sensors etc. etc... these are all setup in the flash ic and not in the firmware...

Sometime the manufacturer release a new version of firmware, that's true, but then you have a big problem because I would never trust a car maker who sell his cars and after a while they release several firmware update.
That would mean their cars electronics are crap...

This is just a very small portion of the reality, I could write and write and write... 🙂
