i have the FlashScan V2, and yeah i was reading your thread https://www.performancetrucks.net/fo...tuners-439111/

In the instructions it says
connect 0-5 output to third party datalogging system or aftermarket ECU. Tip:to interface with your third party application, use the gray wire supplied in your sm-afr connect kit. you will need to know the diagram pin out of your specific vehicle .

It also says not needed for stand alone setup

 

I have an LC-1, I dont know what the AEM is like. If it has the connection for a serial port, use that. You can use the wires, but the serial port is quicker, and easier. There have been people reporting that the reading is sometimes off with the wires unless you calibrate it (basically you just calibrate it with a narrowband to make sure).

 

this might help.

AEM EUGO Lambda W/B how to connect to Flashscan V2

 

With the AEM, I believe the blue wire is what hooks in to the flashscan cable. Where, I don't know. On the box that changes the serial connection to USB, there are connectors on the side, one of those is where the wideband serial wire connects to. You'll have to figure out how to select that port within EFILive. I tried when I had Justin's cable, but I only had a limited time so I didn't get to play with it much, and didn't get it figured out.

 

Lol i have the PLX Dm-6
