Installation points to remember
This product is designed for fuel-injected, automatic transmission, or vehicles
with manual transmissions.
Important: The default option “Manual Transmission Mode”
is a safety precaution that forces the installer to enable the
Manual Transmission Start (MTS) routine or program the unit
to the “Automatic Transmission” option before the remote start
can be activated for the first time.
The “Automatic Transmission” option should be programmed on to work with
automatic transmissions. When the “Manual Transmission” option is selected a
specific routine is required before exiting the vehicle to enable the MTS mode.
➤ Virtual Tach
Virtual Tach is a new feature for Directed this year. It is the default RPM-sensing
method for the new Responder hybrid security/remote start systems. Virtual
Tach gives the installer the performance of a hardwired tach wire, with the
convenience of voltage sensing. It is far superior to any voltage-sense feature
you’ve tried before.
Virtual Tach monitors the cranking voltage of the vehicle using a very fast micro-
controller and an analog-to-digital converter. The microprocessor “saves” the
base voltage as a reference. When Virtual Tach “sees” the slightest uptick in
voltage, indicating that the alternator is charging the battery, the starter motor
shuts off instantly.
