As Ron says, FIKI is done, and existing airplanes were/are scheduled to be retrofit with FIKI, just like with Avio NG and the aeromods. But here's the catch. If you bought an early Eclipse, then the additions would be done under warranty. Note that Eclipse is selling these aircraft AS IS. That means they are not currently scheduled for the upgrades, nor will Eclipse pay for them. The cost of the upgrades will be a negotiable item between the buyer and Eclipse.
Adding FIKI involves a handful of things. The most expensive part is that a bank of switches in the panel that is built into a computer board will have to be replaced to add a switch. The rest, as I recall, amounts to odds and ends. I have the details somewhere, and if someone wants me to look it up I will.
