Well since there hasn’t been many new topic lately, i want to bring up our ecus. In particular the B8 ones at the moment, not the B8.5.
It has always been noted that you cannot easily swap an ecu in our cars without having to go to the dealer to have them pair or activate it.
Doing some looking online, there is a shop that claims they can remove the immobilizer from our ecu!
Would this in fact make it possible to swap ecus from say a stock one to a tuned, or yet be able to sell off a tuned ecu before selling it, or to try out different tunes on the same vehicle?
I have been meaning to play with a spare ecu i have, but its for a DSG and my car is a 6 speed, so it wouldnt work out too well.
I have identified the EEPROM inside the ecu that holds the immo data, just need to figure out what bits to zero out to remove the immobilizer from it.
I have also though of reading my friends DSG EEPROM data and loading it on the spare i have and seeing if the car will run without dealer interaction.
I am not sue what other encryption the dealer has put on our ecus, but one would think if you can disable the immobilizer, what else would prevent it from being able to swap from one car to the next.
I have found a lot of information and programs to remove the immobilizer, even ones for the same chip inside, but none for the simos 8.4
Thoughts?
Here is the place that claims they can remove the immo from our ecus.
