eh, modern ECUs, accident compute, etc are doing timing and tuning calculations in real time such that you need something a little more adequate. A 40mhz PowerPC CPU with an FPU, for example.
Aside from mandatory ADAS, most cars can definitely get away with "90s tech" but probably not "80s tech"
- martin8412 3y agoThe 6502 in my argument was meant for something like controlling seats or mirrors. The ECU obviously needs more compute power. That said 6502 was an over exaggeration.
