Timing Computer-Fixed Curve

MSD Ignition

• Accurate electronic timing curve.
• Adjustable high speed retard.

The PN 8980 Timing Computer has a pre-programmed timing curve that eliminates the need for a mechanical advance.
When you start the car, the Timing Computer retards the timing 20° from the set mechanical timing. This provides easy starting and smooth idle. The timing begins to advance when the engine speed reaches 1,000 rpm and continues until 3,000 rpm when the total timing is reached.

The Timing Computer also has a separate high speed retard circuit. This allows you to activate a retard amount via a switch to retard the timing during times of nitrous or high rpm. The retard amount is adjustable with plug-in modules and 2°, 3° and 4° modules are supplied. Page 90 has a full selection of modules and selectors.
