OEM EFI computers

[Zublin, Bryan (SD-MS)]

Has anyone taken an old OEM EFI computer and modified for his own use?  I'm 
thinking about all of the EFI computers that must be out there on cars that 
are junked.  For example, I believe that Chrysler's use the 68HC11.  There 
must be thousands of these out on the road by now, with some available from 
junk yards for relatively low $$$.  Assuming that the firmware is stored in 
external ROM, it would be relatively easy to re-program.  BZ
