Reply to "Setting idle timing with IR FI"

Doug,

I assume the engine management electronics you are using has no way to control the idle speed, and that the idle speed is set with a butterfly stop screw, just like a carburetor. If I'm wrong, ignore the following.

Monitor what vacuum signal is available to you, plumbing a "canister" between manifold & vacuum gage will even out pulses, provide more of an average reading. Twist the distributor to provide highest vacuum signal. Readjust the idle on 2, 4 or 8 throttle bodies, depending upon the configuration (equalize vacuum, or equalize airflow).

Return to sleeping on your bed of nails.
