I have found a good source for the air temp sensor. Ducati sells the Weber Marelli ATS04 air temp sensor for about $48, BCM in New Hampshire stocks them. The other source I found is Webcon. It used to be the WAS009, that has been replaced by the WAS016, which is exactly the same. The price is GBP10.60 plus shipping. Contact info below:

Not stolen, just borrowed I had a hard time sourcing many of the numbers on your sheet in the US, maybe you can do an update with the new number replacing the WAS009 with the WAS016 and the contact info?

Thanks for the info, I'll update the Webcon part no. on the Elefant's EFI website as soon as possible. There is already a link to the Webcon website over there, so adding contact info is not necessary.

@ Laddie: You cannot steal any info from that website , it is there to take. And guess where I got the info from in the first place? It only took me several years to gather everything together, especially the cross reference no.'s from OEM and aftermarket suppliers.
