The SBC combines the 6 rs485 channels into an "engine wide" rs232 stream. Currently there aren't many of these in the world, (three?) and the protocol is kinda strange so I doubt anyone has shipped anything. In the case of SFS their EAU does the same kinda thing for analog motors. Greg from http://hometown.aol.com/enginfosys does the EAU software and will be adding a SBC input so no software changes are required for the SFS. (SFS does plan to accept SBC input, but their certified program is absorbing most of their resources. Greg is the programmer to watch, even though he hasn't started one line of code because there are no SBC.. :-( plan on using the only existing software that turns a laptop into a 485 bus master. > While there will be some data need by the VM1000 on the other side of the > firewall (oil pressure and temp?) most things come from the SBC, but plan on an external OAT and fuel probes. also the install could use a fuel pump relay, and 6 cyl iodiot lights. the advantages of FADEC are: 1) no mixture to adjust 2) each cly is independently monitored so it should be very smooth disadvantages: 1) expect to run in best power mode unless lower then 2,300rpm http://www.avweb.com/articles/pelperch/pelp0018.html IO-550 std day WOT (recommended cruise 220hp) alt rpm hp 8k 2300 210 3k 2300 245 8k 2500 220 3k 2500 265 2) no best economy mode above 75% rated HP 3) more wires. (yes, lots more) 4) FBO wouldn't have parts or know what to do with your motor. 5) at least $8k more, excluding SBC and extra wiring. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> LML website: http://members.olsusa.com/mkaye/maillist.html LML Builders' Bookstore: http://www.buildersbooks.com/lancair Please remember that purchases from the Builders' Bookstore assist with the management of the LML.
