Sensor Mounting

FIGURE

2. Sensor Bung and Sensor Mounting

A high flow stainless steel weld-in sensor bung is supplied for sensor installation
(additional sensors & bungs are available 30-2063). The bung is specifically designed
so the sensor can provide accurate AFR readings with minimal flow intrusion and
survive extreme exhaust gas temperatures. Pick a mounting location(s) that allows for
easy access to the sensor(s). The sensor tip must be exposed to exhaust gas in order
to give accurate AFR readings. For thin wall tubing, drill a 15/16” hole and weld in the
bung. For thick wall tubing/ castings, drill a 1 1/16” hole and weld in the bung. The
sensor must be mounted at an angle of at least 10 degrees from horizontal in order to
prevent liquids from collecting in the sensor housing. See Figure 2 below. NOTE:

THE OPTIONAL AEM EBP (EXHAUST BACK PRESSURE) KIT (PART # 30-2064)
MUST BE USED IF SENSORS ARE MOUNTED PRE-TURBO.

Controller Mounting

Mount the controller using the supplied 6-32 x 1 ¼ stainless steel screws and nuts. See
Figure 3 and Figure 4 for mounting holes and footprint size.

POWER CONNECTIONS

RED – Connect to a switched, fused (20A) 12-volt power source that is on only

when the engine is running.

BLACK – Connect to a clean power ground.

AEMnet CONNECTIONS

AEMnet

AEMnet is an open architecture software and hardware interface based on the CAN 2.0
specification, which provides the ability for multiple enabled devices to easily
communicate with each other through a single cable. The hardware connection is made
through a Deutsch 4P DTM connector and contains 12 volt switched power and ground
(2A max) as well as the CAN data lines. Devices connected to the AEMnet transmit
data through this one connection and most of these devices receive power from this
same connection as well.

Connection via AEMnet/CAN is recommended as it is the easiest connection (only
needs one connection) and it eliminates the possibility of any analog voltage
losses/offsets commonly associated with analog inputs/outputs.

AEMnet PRODUCTS

The following AEM products are currently AEMnet enabled:
Series 2 Engine Management System
EMS-4 Universal Standalone Engine Management System
4-Channel Wideband UEGO Controller
AQ-1 Data Logger
Wideband Failsafe
Each 4 CH UEGO controller wiring harness has 2 connectors for accessing the AEMnet

(Refer to figure 5), one for accessing the network and the other for an expansion to
other devices.

FIGURE 5. AEMnet Connector

Page 6 10-2340 Rev 05 121012

To join the AEM network, connect the Deutsch male connector to the female connector
of another AEM devices in the network (Figure 6).

SERIES 2 EMS

When connecting to a Series 2 EMS, an AEMnet branch will have to be added to the
factory harness. AEM has several AEMnet to Series 2 EMS adapters available. See
Table 1 below for a list of the part numbers and corresponding Series 2 EMS units.

NOTE: THE SERIES 2 EMS DOES NOT USE INFORMATION TRANSMITTED ON
AEMnet FOR 02 FEEDBACK. THE SERIES 2 EMS USES THE ANALOG INPUTS
FOR 02 FEEDBACK. SEE THE SECTION ON ANALOG INPUTS FOR INFORMATION
ON CONNECTING THE ANALOG INPUTS.

NON-AEM PRODUCTS

Each AEMnet connector has 4 pins. The AEMnet pinout is listed below in Table 2.
NOTE: Pin numbers are located at the back of the connector. Non-AEM devices can
connect to the AEMnet by connecting their CAN +/- wires to the CAN+/- wires on the
AEM network. The connectors are shown in Figure 7.

Figure 7. Connector Assembly

NOTE: the 4 CH UEGO controller has one terminating resistor. If an additional
terminating resistor is needed, one must be installed on the other device.

There are 7 different cylinder numbering combinations available on AEMnet. The
different combinations allow for easy installation and data analysis, and allow users to
connect up to three 4 Channel UEGO modules on AEMnet. See Table 3 and the
figures below for recommended connections on some of the more common engine
configurations.
