I was considering doing this on my elefant. I read something about a guy that used a microsquirt to replace the computer on his 1150gs. He had it setup so he could change his fuel tables and such with his palm pilot.
Some of the DIY fuel injection systems I have looked into(For a hotrod project) have a self learn function. You put in some generic fuel tables and it will correct them when in the tune setting. I ended up getting a link 4 system but have had to put it on the back burner untill I get some more time.
Very cool, please keep us updated.
