Wideband does not read correct with V2

[nitrorocket]

Boy, this new V2 upgrade I did has so far been about as big a nightmare as my recent divorce...

I finally got everything squared away. I hook up my LC-1 wideband to the V2 and I get about a 7.5-8.5 AFR. It worked perfectly with my V1.

I have the blue to ground, yellow to the AD1+, Green& white to AD1-, and red to battery. Not sure what is going on and or what changed since I ran it last with my V1 setup.

Any advice?

Have you calibrated the V2 analog inputs? Have you used Logworks to verify the LC-1 analog output programing has not changed (I recently had an LC-1 mysteriously reset itself to factory defaults)? Have you considered logging the LC-1 via the serial connection?

Not sure how to do any of that. Its wierd. If I have the lc1 pluged into the v2 and start logging, it shows .1 vols on the lc1 in efilive. If while syill logging with efilive, I unplug and then plug the lc1 back int the v2, it will instantly pop up with about 2.8 volts.
What is the fastest way to verify the lc1? Do I have to use logworks? is that the software that comes with the lc1? I damaged one of the two plugs that come out of the lc1 box years ago so I am not sure I can use logworks...this is such a mess.... lol.

Thanks!

Did you damage the "IN" or "OUT" plug? Your laptop must be connected to the "OUT" plug (with a USB to serial converter if your laptop does not have a serial input). The terminator, which is actually just a short must be plugged into the "IN" plug.

The V1 has two analog inputs on the orange connector and a ground. The V2 has 4 analog inputs each with it's own ground.

If it has been a while since you have set things up and you are unsure of the material condition of the LC-1's plugs and the V1 reads the info ok, you could just have the wrong LC-1 channel in the V2's analog input 1 connector. (Swap yellow or brown lc-1 wires into the V2 connector).

Get this figured out and then dive into calibrating the V2's analog input.

use the LMProgrammer software to set your analog out voltage
to a constant. (1-5 volts)
then you compare the set voltage to the logged voltage.
also make sure your fuel setting is proper.

Why even mess with Analog wiring , just buy or make the digital input wire for the LC-1 to V2 and have much cleaner data , much easier also .

If you have V2, why don't you simply go with serial/digital AFR... see the link in TAQuickness's sig.
