I really don't have anything new to add. The winter stalled me out again this year, but I am hoping to get back into the swing here this week. Next on my list is to add a small fuse box to allow for power to the accessories not directly controlled by the ISIS system. Things like the radio, heater fan, and dome light. Right before winter, I did get the core electrical all solid and ended up flashing my XFI ECU from version 1.0 to 2.01. There was a bit of a learning process that went on during that, but glad I did. Made me much more comfortable about the fuel injection system and how it works.
