In the automotive world (with the exception of infotainment and assisted/autonomous driving systems), ECUs have amounts of RAM measured in kilobytes, not megabytes. I've left the industry now, but I /think/ the powertrain ECUs I worked with usually had around 256KB of RAM.

That is a fascinating world to me. I've about 25 years C, rudimentary intel x86 asm and good ability to understand new hardware. Seems to me that at 40+ this is an industry that I could still be of use in. Any pointers?
