Smart Tachless, Tach Reference, & Tach Finder Modes - CrimeStopper CS-2015.FM.RevB Installation Instructions Manual

SMART TACHLESS MODE
Both the CS2011RS & CS2015FM include a Tach-less engine monitor called "Smart Tachless" mode. When in "Smart
Tachless" mode, the module actively monitors the vehicle's voltage reference each time a remote start is performed.
Smart Tachless mode will adjust itself to maintain optimum efficiency over the life of the life of the installation.
No special wiring is required for Smart Tachless mode. The Smart Tachless system works from the existing 12V
power connection of the unit.
CAUTION: DO NOT USE or CONNECT WHITE/RED TACH WIRE FOR SMART TACHLESS MODE!
SMART TACHLESS JUMPERS: (Remove Access Door on top of module)
The purpose of the jumpers is to reduce the starter cranking time [if needed] when in "Smart Tachless" mode only.
To shorten the crank time by one percent remove jumper #P2. Test the unit and see if the decrease is correct. If a
shorter crank time is still required, then remove Jumper #P1, which will reduce the cranking time by another percent.
Test the unit and see if the decrease is correct. These are the only two "Smart Tachless" adjustments.
IMPORTANT SMART TACHLESS NOTE:
NOTE: Smart Tachless Mode is NOT guaranteed to work on EVERY vehicle. Occasionally, older vehicles, Dual-
Battery Systems, or out-of-tune vehicles will not operate properly in Smart Tachless Mode. On the rare occasion this
was to happen, use a Tach wire and program the unit for Tach (RPM) Reference Mode.
TACH (RPM) REFERENCE MODE & TACH FINDER MODE
Tach Reference Mode provides reliable remote starting performance though engine speed sensing. When using
Tach Reference Mode, the WHITE/RED wire is used for Tach signal [Engine RPM] input. Most modern engines
include various points where the Engine Speed [Tach] or A/C signal may be obtained. Tach Signal examples:
Negative (-) side of ignition coil, at the Distributor or Ignition Control Module, Coil Pack, Engine Computer, or
Crankshaft Sensor. Sometimes Fuel injection solenoids, and Alternator stator pins can be used. These Tach Signal
locations mentioned are provided as a guide, your vehicle may differ. Some locations will NOT be a good location for
Tach source due to RF noise or Computer Data. Use the TACH FINDER mode to locate a valid tach source.
TACH FINDER MODE:
This system now includes a Tach Finder mode to assist in locating a valid or viable tach source for your installation.
Follow the Tach Finder steps to locate and /or verify a tach signal. When following the steps, the unit will begin to flash
the parking lights if you have the White/Red wire connected to a valid tach source. If lights do not flash, then try
another wire until you locate a tach signal that will cause the Parking lights to flash. NOTE: On some vehicles
equipped with daytime running lights, it may be difficult to see any flashing parking lights. In this case your only
notification will be the slight "ticking" sound coming out of the module from the on-board flashing light relay.
