Dyna 4000 Pro Two Stage Retard Module

Dyna 4000 Pro Two Stage Retard Module

The DYNA 4000 Pro Two Stage Retard Module (TSRM) is an accessory component for use with the DYNA 4000 Pro Ignition System. The Two Stage Retard Module provides two independently adjustable ignition retard stages that can be activated during a run. You actually end up with three timing settings that can be activated during the run: the static pickup timing and two stages of retard. Each retard stage is adjustable from 2 to 20 degrees retard in 2 degree increments.

Each retard stage is activated by applying a 12 volt signal to the retard trigger input corresponding to each stage. The 12 volt retard signal can be generated many ways. Several suggested ways of activating retards stages are listed as follows:

Use the 12 volt power to nitrous solenoids to activate retard when nitrous solenoids are energized.

Use a Dyna Pressure Switch to activate retard when boost goes above a preset level.

Use timer to activate retard after a preset delay.

Use a Dyna Shift Minder to activate retard above a preset RPM.

Use a Dyna Shift Counter to activate retard stages according to which gear you are in.

Use a toggle switch to manually activate retard.
