 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:
1. Use the 12
volt power to nitrous solenoids to activate retard when
nitrous solenoids are energized.
2. Use a Dyna Pressure Switch to activate retard when boost
goes above a preset level.
3. Use the timer to activate retard after a preset delay.
4. Use a Dyna Shift Minder to activate retard above a preset
RPM.
5. Use a Dyna Shift Counter to activate retard stages
according to which gear you are in.
6. Use a toggle switch to manually activate retard.
