i see the thread!! doh!!!! :chair:

I can get the afr info on the blue box but not on the computer log? what pid do i need to chose?

Go to the bottom of the pid list, you will see analog wideband, and serial wideband. choose how you are hooked up, and look for #1 for your brand of WBO2 with AFR in the name.

Look here also for the cable info

Red Cable is Transfer
White Cable is Received
Blue and Black are ground

You have to either:
- insert a null-modem gender bender ($3.00),
- make your own cable.


See this thread: serial-port-cable-that-goes-to-v2

alright so i can simply go from the molex connector on my lm2 to the serial data input on my v2 correct? i seen the pics from page one just want to double check.

I have just connected mine and the wiring is as follows:
Molex RJ12
1 (red) Pin 1
2 (white) Pin 2
3 (Blue) Pin 5 or
4 (Black) Pin 5
