I'm new to dealing with this EFI setup, so bear with me.
Currently I'm converting an carbed engine (chevy V8) over to FI and electronic ignition. I have to install the electronic dizzy right now.
Do you have to set these at a fixed advance of 8-10° like a conventional dizzy or are these installed with the rotor at 0° advance and does the ecu figure in the advance at idle ?

Check it out, we've got a detailed write-up of swapping a computer controlled HEI ignition onto our Chevy Nova:

Re: installing FI dizzy
Matt,
I'm a bit confused by the wiring schedule you have there. The dizzy from MSD is the same, but I have a coil with only a + and a - to connect. How do I connect it ? BTW I have an electronic tach that was fed of the original coil in cap HEI.

Re: installing FI dizzy
The coil in that diagram actually just has + and - terminals too; it's just that there are two wires connected to each.Yves wrote:Matt,

So, if I'm not mistaken, I can run a battery + to the coil and from the same connection on the coil to the dizzy and the - from the dizzy to the negative from the coil and to the tach ? Do I need a resistor with this setup ?
Sorry if this is maybe a stupid question, but don't want to fry anything.

Re: installing FI dizzy
Correct, and no resistor needed.
