Overview

The Dedenbear ST1 is a shift timer designed to automatically complete one shift cycle at a user-selected RPM. This enhances consistency in elapsed times (ET) and allows the driver to maintain focus on the steering wheel during critical moments. It features a straightforward design with minimal moving parts for reliability. The ST1 works with standard ignition systems and incorporates user-friendly push-button thumbwheels for adjustments, along with a built-in delay function. It is often integrated as an RPM Switch module in Dedenbear Solenoid Shifter systems.

Part #: ST1

The Dedenbear St1 Is A Single Stage Timer That Can Be Used To Activate A Device Such As A Shifter, Throttle Stop, Nitrous Solenoid, Or Timing Retard Based On Time Rather Than Rpm. The Shift Timer Works Particularly Well In Cars That Have Loose Converters. The Engine In A Car With A Loose Converter Tends To Run At A Fixed Rpm Until The Converter Locks Up And Stops Slipping. Since The Engine Runs In A Narrow Rpm Band Near The Intended Shift Point For A Large Portion Of The Run, The Actual Shift Point Can Vary Widely. The St1 Will Allow The Car To Shift At A Precise Point During A Run And The Engine Rpm Doesnt Matter.

Features:

  • Adjustable timer from 0-9.99 seconds programmed with push button thumbwheels
  • Selectable output of 0.5 second pule for applications like shifter activation, and long 17 second pulse for applications such as nitrous oxide, throttle stops, etc.
  • Output Terminals are Normally Closed and Normally Open to either apply or remove 12V power
  • Release of the transbrake or line lock solenoid starts the timer at the beginning of the run.
  • Small size for maximum mounting versatility. Measures 6.50 in. W x 3.38 in. H x 1.25 in D.
  • Compatible with 12 and 16 volt electrical systems
