i would never try and flash an ecu as old as ours when we dont have any support on the matter. our ECM's arnt even made anymore, even cummins cant sell us a new one... any time you flash you want to have some control over it and to my knowledge no one has managed to dump the factory ecm programming so there is no way for anyone to unbrick them in their garage. if we had the raw code then perhaps you could solder to data viers on the board and force a sector write back to the chips - ive done this on routers, play stations, dream casts and so on but in every case we had the source code.
your best bet is to just send the ecm out to a rebuild company and either buy a new one with trade in or get it 'rebuilt'. you may be able to find a used one at a salvage yard some where. i managed to find my new ecm for about 100 bucks but a safe bet is around 1K.
