JECS ECU Instruction Set

[avos at cochlear.com.au]

     Does anyone know where I can get get the instuction set used by a JECS 
     ECU. JECS ECUs are used by quite a few Japanese cars including my 
     Subaru, and I would like to see what it is doing as I have been able 
     to download the standard ECU map out of the ECU.
     
     Thanks,
     
     Adrian
