1. Addendum Note
This manual is an addendum to the AFR500V2 Tuning Manual. For
installation & tuning information, please see the AFR500V2 Tuning
Manual.
2. Introduction
The AFR500CAN should be configured using the AFRCAN
Programmer software. CANbus message IDs, baud rate, data rate, and
other settings may be adjusted. There are options for choosing some
preprogrammed outputs for use with CAN Enabled ECUs, OBD2
ECU tuners, aftermarket gauges, dashes, & loggers.
3. New features in the AFR500CAN
The AFR500CAN is a major iteration on the AFR500V2. All
features & functions of the original AFR500V2 remain intact with the
added improvements below:
•OBD-II Compatibility. Works with most 2008 and newer CANbus
based systems.
•CANbus output on IDs 1h-7FFh(11-bit) or 1h-1FFFFFFFh(29-bit)
•USB-CDC Serial Output for HPTuners & EFI Live Software
•AFRCAN Programmer software for:
-configure CAN interface
-configure CAN ID/bitrate/frequency/PID
-update AFR500CAN firmware
-configure AFR500 Range
4. Kit Contents

• 13ft (standard), 7ft, or 24ft wiring harness
•AFR500v2 Tuning Manual
• Weld-in sensor bung
• Screw-in sensor plug
• Adhesive backed hook & loop pair
• 3 red configuration jumper contacts
5. Functional Description
The wideband controller AFR500CAN can communicate the current
lambda O2 reading over can through OBD2 inline adapter or by
plugging into a CANbus expansion hub or ECU.
6. Wiring Installation
The DTM-6S wiring pinout follows:
3. White wire –CAN + high
4. Black wire –CAN - low
If not using a premade adapters harness, Pin 3: CAN+ high and Pin 4:
CAN- low should be used to connect to the CANbus.
For Haltech, Motec, AEMnet using the appropriate adapter harness
plug, you plug the 4 Way DTM connector into a receiving CANbus
connector or hub. Then plug the 6 Way DTM connector into the
DTM-6P USB/CAN connector coming from the back of the
AFR500CAN unit.

For OBDII setups (HPTuners and EFI live)
1. Plug in the OBDII adapter harness to your cars OBDII port,
then plug the device in to the adapter harness.
2. Plug the other end of the adapter harness with the 6 Way
connector into the DTM-6P USB/CAN connector coming
from the back of the AFR500CAN unit.
7. Setting & Explanation of Options
The AFR500CAN has an internal 120R terminating resistor that is
enabled using a jumper. It is installed by default from the factory.
8. AFRCAN Programmer Setup
The AFR500CAN may be configured using the AFRCAN
Programmer software. CANbus message IDs, baud rate, data rate, and
other settings may be adjusted. There are also options for choosing

some preprogrammed outputs for use with HPTuners, EFI Live, Serial
Out, AEMnet, Motec, Haltech, and Default CAN. Default CAN is
useful for programming into ECU Master and Megasquirt 3 ECUs.
Installation
1. Download the software at
bmotorsports.com/download/software/AFRCAN_Programmer
.exe . Double click "AFRCANProgrammer.exe" to install.
2. Once installed, Start the AFRCAN Programmer software.
3. Power up the AFR500CAN from a 12v power source using
the main harness. The AFR500CAN will not operate via USB
power.
4. Plug in the USB adapter harness to the AFR500CAN then to
your computer’s USB port.
5. Open the Port Settings and click refresh. Locate the COM Port
labeled “AFR USB”and click connect.
6. Next, click the "Connect" button, then click on the menu
"Configuration" to return to the main window.
Configuration
1. Before changing any settings, we must first retrieve the
current configuration, do this by clicking the button labeled
"Read/Verify Configuration", once successful the message
"Configuration Retrieved" will be displayed at the bottom.

2. The Interface drop down menu lets you choose an option
which will preconfigure the settings to that option's default
settings (ID, Baud, Rate). "Default CAN" defaults to a generic
message output structure for use with most stand-alone ECUs
(See Section 16. for message structures). “Serial AFR”and
“Serial Lambda”will output a signal over the included USB
cable for VCM Scanner serial wideband feedback.
3. CAN address ID: The first box is for
changing the CAN ID (Default is 0x500, 11
bit), there are options for displaying the ID in
hexadecimal or decimal and 11-bit or 29-bit
(Extended ID).
4. Baud Rate: The second box is a drop-
down menu for changing the CANbus
Baud Rate (Default is 500kbps).
5. Data Rate: The third drop down menu
is for selecting the Data Update Rate
(Default is 100Hz).

6. Range: The Range drop down MUST
match the Jumper 2 setting on the
AFR500 circuit board or the CAN
Output will be wrong!
7. No jumper = Standard (Default), 9.0-16.0
GASOLINE, 0.618-1.098 LAMBDA
Jumper = Extreme, 6.0-20.0 GASOLINE,
0.411-1.373 LAMBDA
9. HPTuners VCM Scanner Setup
Note: If you are having trouble connecting you
may need to change the CAN ID from the
default 7E5. Connect the VCM Scanner
without the AFR500C connected and go to the
“Details”tab to see you what CAN IDs are
being used by the vehicle. Usually the hex ID
is followed by “, CAN”(Note: OBD2
CAN IDs respond as the base ID plus
8 for example IDs 7E0-7E7 respond as
7E8-7EF). Some newer vehicles may
need to check the “Extended 29-Bit”
in AFR CANProgrammer.

1. With the HPTuners
USB cable plugged
in and the car
powered on, open
“VCM Scanner”and
click on the “Vehicle”menu then select “Connect”.
2. After connecting you will need to
add “WB EQ Ratio 1”to the
Channels window. First click on
the gear with the green “+”.
3. In the tree navigate to "OBD Controller: TCM (0x7E5)" [7E5
is default, ID may be programmed differently], "Engine",
"Fuel", "Open & Closed Loop", "Oxygen Sensors" and double
click on "WB EQ Ratio 1 (SAE)".
4. If “WB EQ Ratio (SAE)”doesn’t show up you may need to
click “Repoll For Supported Parameters”from the “Vehicle”
menu.

5. Next select “Start Scanning”
from the “Vehicle”menu. This
will start logging the vehicle
parameters, you will see
lambda values displayed in the
right column.
6. If you prefer to view AFR you can right click on "WB EQ
Ratio 1 (SAE)" and “Units”select the AFR for your fuel type.
Note that this may not match the AFR500CAN display whose
stoichiometric reference is 14.56 (Indolene Clear).
7. Near the bottom of the “Channels window is a tab labeled
“Details”which display the AFR500 controller properties and
CAN ID.

10. HPTuners Pre-CAN VCM Scanner USB Serial Setup
1. Plug in the AFR500C USB
programming/serial cable to your
computer.
2. Using Section 8 “AFRCAN Programmer
Setup”retrieve settings, then change the
“Interface”to “Serial AFR”for air-fuel-ratio,
or “Serial Lambda”for lambda.
3. With the HPTuners
USB cable plugged
in and the car
powered on, open
“VCM Scanner”and
click on the “Vehicle”menu then select “Connect”.
4. After connecting you will need to
add “AEM - AFR”or “AEM - EQ
Ratio”to the Channels window.
First click on the gear with the
green “+”.
5. In the tree navigate to "External Inputs", "Serial Port", "AEM"
and double click on "AEM - AFR”for air-fuel-ratio, or AEM -
EQ Ratio for lambda. (Note: this must correspond to the
“Serial AFR”or “Serial Lambda”Interface setting in
AFR CANProgrammer settings.)
