How can i troubleshot the problem?
2002 Z28 HardTop M6 (408cid, F1C'd, 800rwhp+)
2009 Z06 2L2 (Cammed 500rwhp+)
Is the LC-1 powered up...?
On the V2 go into the wideband display, does this show AFR/Lambda values...?
In S&T Device Settings did you enable the serial/digital pids...?
Post some log files.
Im still trying to find the problem... I hooked the LC1 to a digital gauge and it showed readings in the 30's which means it is working, but maybe it is not calibrated properly. I thought the LC1 comes calibrated. I'm going to raise the scale in the A/F graph to 40 to see if i can see any movement. If that happens i will have to recalibrate the LC1 again i guess.
Ok so far i checked all PIDs with serial connection and there is no activity on the scanner or the PC.
Im going to try the analog route now to see if I can get some activity to the V2 software at the least.
Good news... the analog readout works which means that the serial way didn't work for me.
Now i have to find a way to change the reading from 0-1 and translate it to 7-22 A/F
Good news... The analog route worked and it is showing me movement in the AD1 an average of .55 and a max reading of 1.09.
Now i need to find a way to translate that into a custom PID so i can log it properly.
Where in the v7.5 can i create a PID? Never done a custom PID before or even changes the value on one.
Did you use a null modem adapter...?
It has to specifically say "null modem" on it.
See post #3: showthread.php?9340-serial-port-cable-that-goes-to-v2
Did you enable serial wideband in the V2 setup options...?

The adapter will allow two male serial ports to be merged. It has a sticker on stating "Mini Gender Changer" LMAO. It looks the same as pictured in the post you referenced.
Also something interesting i noticed, when i went to the setting in the V2, i only found Port instead of Com In & Com out as pictured in the "Serial Wide band Tutorial". So i choose Wide-02 and Innovative, but it did not work.
A gender adapter is not sufficient... the null modem cable cross connects the Rx and Tx pins, like this:
