Rawze's VGT turbo controller box

[jmartin]

Perhaps something like [/size]this would be a good choice for such applications. Infineon dev board with Aurix TC237 series tricore micro, onboard CAN, touchscreen etc. Meant for automotive controller development. With the three cores, one could be handling J1939 while others can be doing the real work. If you're an OEM or Tier 1 they hand these out, but I'm pretty sure you can buy these Dev boards on Mouser, etc. Not quite as cheap as Arduinos, but much more powerful.
