For the AEM 30-0300, the gauge and controller are 1 piece. i.e. not a seperate controller/gauge like PLX, et al. So, all of the outputs are available.
EFILive SHOULD be able to pick up the OBD2 simulation data from the CAN bus on the modified units. It's just the normal PID 0x24 format. If you wanted to go that way.
The manual is here : http://aemelectronics.com/files/inst...or%20Gauge.pdf
The OBD2 simulation mode stuff is not covered there, as it is a special re-flash mod that I am doing.

Ok, it is an intgrated wideband controller/gauge... and the user manual indicates it writes the AFR on the serial comms port... so EFILive FlashScan V2 is able to read it...
you need a serial null-modem adapter (gender bender) to join the AEM serial cable to the EFILive V2 cable... and need to configure V2 serial com port to "wideband" and type to "AEM"...
then connect to powered up OBD-II port on vehicle, and V2 LCD can display wideband AFR and Lambda, and you can log those as external pids (pids are named EXT.WO2xxx).

What would it take for EFILive to read the lambda information from the OBDII/CAN interface ? It just shows up as the standard PID.24 , using a splitter on the OBDII cable.
The CAN/OBD2 data can be scanned at up to 500Hz. The default for the serial data is only 10Hz. This is significant because the gauge has a t63 response time of around 10ms. ( 100Hz )

The serial com on the gauge is just an open output. Nothing is reading it, unless you connect something to it. So, there is no need for a repeater.
The display function does not use any of the outputs, for itself. It is connected, internally.
The gauge has 3 outputs.
1. The CAN bus lines
2. The 0-5v analog output
3. the serial output line
All three are available for use.
The mod that I did converts the CAN output to an ECU simulator to serve PIDs 24-2B for lambda data.

Ok.
My question was. Can EFILive read the lambda data from the gauge's OBDII/CAN interface ?
It works with HPTuners. i.e. When the gauge's CAN wires are connected to the CAN wires of the vehicles OBDII connector, HPTuners can read the lambda data directly, via PID 24, etc.

But it will read it directly from the serial comm output (with a null modem serial cable).

do you have the serial comms cable that came with your FSV2...?
do you have the serial comm cable that came with your AEM...?
all you need is a $2 null modem adapter, see orange gender-bender looking device in this pic:
Wow, this is over my head. I only have the V1, so I am hoping to use the analog outputs at this time. Pretty new to tuning, so not sure I want to pay to upgrade to the V2. If I can't figure the tuning thing out I'll just take it and get it tuned, but I really would like to figure this stuff out.
The AEM units have a linear 0-5v analog output iirc
It was the LC-1 innovative that used the serial. I dont remember any $150 AEM gauge every coming with a serial adapter, or any 9pin DB connector.
