8. Select the rev limit using the 6 top switches.
The minimum rpm (with all switches in the "off"
position) is 5,000 rpm. For higher rpm limits, add
the value of the switches in the "on" position to
the base setting of 5,000. See the examples
below.
Note: If your distributor is showing signs of
bushing wear or if there is backlash in the
distributor/cam gear combination, the rev limit
my start 100 to 300 rpm below the rpm that you
have selected.
9. Reinstall the cap and rotor and set the ignition
timing. You may notice a slight timing change now
that you have installed your HyFire HEI Module.
This is normal. If your change is substantial, you
may have reversed the pick up wires.
