At 50 MIPS you could EMULATE an HC11 on a Scenix, maybe even faster
than an 8 Mhz HC11. The 2 kWord PIC sized memory space may just be enough 
to do it (although you'd miss out on the 11's peripherals)!

I will say however that the 68HC11 is a "traditional" microprocessor, and,
for anyone wanting to understand micros, this is a great chip to start with,
and certainly easier to understand than the instruction set of a PIC variant.

Also, the  PIC programming model is not very useful for the large code space 
required for a modern EFI/IGN system.
