I've just done a quick web search...
The FIM website is a bit confusing as for the 916SP (94-97) it has a "standard chip" of 056/057
This article says:
"The data is actually for the genuine factory 916SP chip which comes with the bike to be fitted with the SP's large diameter Termignoni mufflers. In Ducati parlance it's an 056 chip. " http://www.epicycle.com.au/streetbi.htm Another interesting article on the 916SP is here, where he raves about the standard fuel chip in it!

Sorry I can't be of more help, but you may want to try emailing Ducati direct and asking them - they're normally pretty helpful with this kind of thing:
