Installation points to remember
This product is designed for fuel-injected, automatic transmission vehicles only.
Installing it in a standard transmission vehicle is dangerous and is contrary to
its intended use.
➤ Virtual tach
Virtual Tach is the default RPM-sensing method for the new hybrid keyless entry
/remote start systems. Virtual Tach gives the installer the performance of a hard
wired tach wire, with the convenience of voltage sensing. It is far superior to
any voltage-sense feature you've tried before. This feature 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.
➤ D2D
The system has the ability to interface with an Xpresskit module through the D2D
port. The advantage to using a D2D interface is that there is less wiring involved
in the installation. Check the Xpresskit module installation guide to determine
which wires are not needed, and which options are available. For more infor-
mation visit www.xpresskit.com.
