Hi

I am about to do this to my 1967 Hillman Imp.

I will be using a Coil pack, EDIS4 module, VR sensor and 36-1 trigger wheel from a 1.8 CVH Sierra. I will then use a Megajolt Lite Jr ECU to give me adjustable advance curves.

Do a google search for 'DIY EDIS' and there are a couple of good articles about it. Or read this article http://www.theimpclub.co.uk/forum/viewtopic.php?t=2225 which is also very useful.

Hope that helps
Chris
