Interfacing the DLG-1 with the LC-2
1.
Verify that both the DLG-1 and LC-2 are powered OFF.
2.
Both the DLG-1 and LC-2 have 4-pin Molex connectors labeled IN and
OUT. Using P/N 3846 included in your kit, connect the OUT port of the
LC-2 to the IN port of the DLG-1.
3.
Turn the key to the accessory position (do not start the engine) to power
up both devices. Once the DLG-1 is powered up, press and HOLD both
interface buttons for 5 seconds. This will sync the connection from LC-2
to the DLG-1.
It might be necessary to resync the DLG-1 with the LC-2 by pressing
and HOLDING the two interface buttons if additional MTS devices
are added to the serial chain (serial IN port of the LC-2.)

Wideband Oxygen Sensor Setup
2.5.1
Oxygen Sensor Placement
Weld the bung at least
24 inches downstream
of the exhaust port
outlet (after the collector), or 24 inches after the turbocharger if so
equipped. The bung should be welded before the X or H pipe if so
equipped.
Using a clock as reference, mount the bung between the
9:00
o’clock and 3:00 o’clock position
. Welding the bung in the lower
section of the exhaust pipe can result in sensor damage caused by
condensation making contact with the sensor’s internal heating
element.
A
1” bung
(provided in the kit) will best protect the sensor. When
fully threaded, the sensor’s tip will sit flush with the exhaust pipe, this
does
not
adversely affect the readings.
The bung should always be welded before the Catalytic Converter.
Welding the bung after the catalytic converter will skew the readings
toward lean. The skew in readings will vary with engine load and the
efficiency of the catalytic converter.
Leaded fuel and two stroke applications will reduce the sensor’s life.
There are many other factors that dictate the sensor’s lifespan so it is
impossible to predict it’s total longevity.
