I am looking to run my silver top zetec on a set a cbr carbs and edis 4 at the moment until I can get the finances to go fuel injection. What I need to know is what do I do with the PIP (terminal 1) and SAW (terminal 3) wires on the edis unit if I am not using megajolt or similar. Do these just remain unconnected?

You will have no advance function if you leave PIP and SAW disconnected. The engine will run, but it won't be right. You need some form of ecu that can control it, and if you're future plans are full management then it would be best to save up now and buy a full ignition and fuel ecu. Buying a Megajolt etc ecu would only be a short term fix.

You need an ESC unit, not an edis. Look on the trigger wheels site for wiring diagrams.
Edis has fixed 10degree timing meaning it will start, but top out at about 2000rpm.
The ESC units are similar but have a built in advance map plus a take off for a MAP signal from the manifold.
Mk 3 & 4 fiesta and escorts had ESC modules.
Lots of info on Google.

Thanks for the replies. I knew about the 10 degree static timing but did not know about it topping out at 2000 revs. Having a bit of a re think at the moment. I might have to put the injection plan on hold for a while and stick with the cbr carbs and ignition ecu. I have been looking at Nodiz pro, does anybody have any experience of using one.
