I cant seem to get the Wideband gauge to match my SCT LiveLink.

I am using the correct equation (v*1.400)+9

NGK has a GREEN WIRE Signal
NGK has a BLACK WIRE Signal Ground

I have been using the SCT USB Black Wire to NGK BLACK (GROUND) and the SCT USB Orange Wire to NGK GREEN. This is supposed to be Analog #2 in Live Link. The readings just don't correspond with one another. In fact when I disconnected the wires, it kept logging HAHA.

Do I need to do the following instead?

- NGK GREEN to SCT ORANGE (Analong 2 Signal)
-NGK BLACK to SCT BLUE (Analog 2 GND)
- SCT BLACK to chassis ground? (Even necessary??)

Well that didn’t work either haha

Jesus Christ!

All I get is 12.2 for AFR constantly and 2.3V for Orange

I surrender. I have literally tried everything. Still get the 12.2/ 2.3v readings no matter what.

I have SCT White to Fused Power. Green Signal to SCT Orange. Black GND Signal to SCT Blue. SCT Black to Chassis GND. I even took SCT White and applied power. No change.

are you literally connecting the two black (ground) wires together or are they sharing a common ground?

It's been a while since I've hooked up a wideband to SCT, but I don't remember ever hooking more than one wire up to the analog input. I think the green should go to whichever input you're using in the analog plug. The wideband ground should go to chassis ground. I'm pretty sure it needs to be grounded to wherever the power for the wideband is being grounded.

My wideband setup mirrors what 01Yeller is saying. Im not using SCT but I have one analog input going to my DataQ box for the 0-5V reference which is the value being datalogged, that’s it.
