Proper Timing on Computer Controlled set up

[CaliDude76]

Yo fellas,
Need some help..I've got the Computer Controlled set up in my 84 with the E4ME feedback carb. Can't get this thing to idle right...being a real P.I.TA. Been trying to find my way with this.
The ECU controls timing partly..but am I supposed to unplug something to set base timing...and what is a good start for timing?? Any help would be great

They got that tan wire with the black stripe on the firewall, under the hood.
Gotta unplug that dealy.
My truck is set at 10°, but it's a lot faster than yours.
