Every chip ever made that communicates with other chips has a TX, RX, ground pin for loading programs either from divorced storage or onboard. I have an $30 internet IDE MPX programmer that will talk through those pins at a binary level to read or download anything inside memory address by address. It will even enable a write option to secured memory on supported software.
Last I saw they supported 300,000 various chipsets.
The reason that ECU hasn't been publicly hacked is because there was no interest in hacking it, the hack data wasn't published, or there's an easier/better/cheaper method to replace it. What do you know about my unsucessful reprogram of a Delta high power variable voltage lithium charger?
