Came across some sites that could clear up a few things about chips for EEC's for those thinking about it.
are US based and deal with Mustangs but you get an idea of what they do. Check out the data aquisition device that fits to the EEC. Way cool:mmm:
again is US based and a bit dated (1995) but has a list of do's and don't's in modifiying a Stang 5.0.
If anyone is interested I have some US Ford books that deal with the 5.0 engine mods and articles from magazines that I could bring with me to Melbourne on the Ford trip. The 'Ford Fuel Injection & Electronic Engine Control' is good value if you want to understand EEC.
