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?

Not exactly.
Old chips really cannot be hacked, because they use technology that allows writing program only once. Some of them allows to erase memory completely using UV and then upload new program, but definitely not to re-write part of the program on-the-fly.
