Learning The Tach (Not Needed With Virtual Tach); Initializing Virtual Tach (Not Needed With Hardwired Or Data Tach Applications) - Directed Directechs DS4+ Installation Manual

Learning the Tach (not needed with Virtual Tach)

Tach comes preprogrammed, therefore learning is not required; however, it can be readjusted with the following operations:
1. Start the vehicle using the key.
2. Within 5 seconds, press and hold the Control Center (antenna) or the main module programming button, until the LED on the
Control Center (antenna) or the main module turns ON solid.
3. Release the button. The tachometer value is now stored in memory.
If the LED does not turn ON solid, find an alternate tach source.
Note: When the tachometer is programmed, the main module automatically enters the Tachometer engine checking mode.

Initializing Virtual Tach (not needed with hardwired or data tach applications)

To program Virtual Tach:
1. After the install is complete, remote start the engine. The programming operation may require 3 cranks of the starter before
the engine starts and runs. Do not turn off the remote start if this happens, it is a normal programming operation.
2. Once the engine begins running, let it run for at least 30 seconds.
3. Using the Remote, send the Remote start command to turn remote start off. Virtual Tach is programmed. To reset Virtual Tach, a
module reset must be done.
Note: Virtual Tach cannot be used in Manual Transmission Mode. It is also not recommended for diesel trucks.
Virtual Tach handles disengaging the starter motor during remote starting – it does not address over-rev. If the customer wants to
have the over-rev protection capability, the tach wire or data tach must be used.
Important! After successfully learning Virtual Tach, a small minority of vehicle starters may over crank or under crank during remote
start. Use the VirtualTach Fine tune feature using the DirectLink application for mobile devices to adjust the starter output time in
50mS increments to compensate for such an occurrence.
