06 - Input Signal Conditioning Select
Parameter Group:
Setup!
Options:
SPK
- Spark mode signal conditioning (Inductive pickup, Coil -)
TRG
- Trigger mode signal conditioning (TS1-TachSensor, Hall
Sensors, Magnetic pickups)
Default:
SPK
Purpose: This parameter is used to select the source for the event signal
which will be used to measure speed.
How to Set: This parameter must be set to TRG when using the TachSensor. It
must also be set to TRG when connecting to any pulse type signals
such as a Dyno encoder or crankshaft position sensor. When
connecting SmartTach to the Ignition Module Trigger signal
(between the engine control unit and ignition module; i.e. General
Motors EST and Ford SPOUT/SAW), this parameter should be set to
TRG.
This parameter should be set to SPK if the SmartTach input is
connected to an Inductive Pickup sensor (clamped to a spark plug
wire), or directly to the ignition coil negative terminal.
IMPORTANT: Never set this parameter to TRG when connected
directly to a Coil(-) terminal or damage to the
SmartTach mat occur.
