I have a stock 2.0L with after market FI (fuel only).
I am wondering what dizzy to use.
I have a 1.7, 1.8, and a 2.0 dizzy.
Looking at this chart that I copied from the Pelican board (hope they don't mind).
I am thinking about using the 1.8L dizzy.
Do you think it has too much advance curve?
If I do use it, should I set the timming for a 2.0L or a 1.8L?
What do you guys think?

Use the 1.8....you don't need the trigger points.

The total advance is meaningless, in the respect that you are going to time it a 27 degrees at 3K RPM....all of the mechanical advance should be in at that time.

The more mechanical advance built into the unit, the closer to TDC your static ignition timing will be (easier starting).

The rate it comes in at will effect performance, but they all seem about the same.

The vac stuff is mainly for emission control.
