Yeah you don't get much help nowdays. I asked a question on VCT and got nothing. This forum has slowed down.
Try asking your question on the Australian Ford Forum http://www.fordforums.com.au/index.php
Also Turbotorana comes from over your way and fits ems' to falcons (I think) maybe you could ask him.
All you need to do is control the ignition and fuel. So just piggyback and leave the factory computer controlling everything else. You can wire ISC and others into the stinger. I am in the process of wiring an EMS 8860 into a supercharged EF. Slightly different to an EA (no distributor in EF) but the principal is basically the same. I have finished the wiring but haven't started the car yet.
