Can you give us the number off the front of the Fadec unit?, (for example, mine has AU-540 written on it), there are several different versions and revisions to each, however Gaspar Espiel has a manual available for nearly all his units or you can ask here:

Although his english is not the best, Gaspar is allways happy to help as best he can and he supports his Fadec/ECU's very well.

Cheers,
