Different AFR readings
I'm trying to tune in SD but, I notice that my lm-1 is giving different readings than what my histogram is.
I'm seeing 12.5 across the entire board on the histogram but the lm-1 seems more accurate with readings around 14.7
I think something is wrong with the histogram but, does anyone have an idea?
Thanks.

Now, I can not pull up the LM-1 manager. It says it is searching for the device. Analog out is plugged into the black box and then, ran to the lap top serial port.
If the LM-1 is reading correctly while tuning but, it is not showing up correctly in the histogram, I'm starting to think that my EIO isn't working.

I'm pointing fingers at the EIO but, I'm really unsure at this point.
Thanks for your help Texas Horns.

Both your black box and Wide band have to share the same ground to the vehicle. If they don't the readings could be off. You'll find more info on the EFI website. Ground it to pin #4.. Is that how you did it?

Again, just some thoughts... Hoping it's not yer EIO...

Gotcha. Correct, it is not getting a reading. The unit is connected thru a USB adapter. Wouldn't work on my desktop either. But like I said, the LM-1 unit is giving correct readings while tuning. Just, it's not showing up correctly on the histogram display.
Thanks for helping me narrow it down. I think I'll be able to figure it out.

Hmmm. Yeah, I corrected it the first time I ran the wideband. But, I had taken it out since then and now I was going to do some more tuning and I was getting the 12.5 readings.
I went to set it up, using the LM-1 manager but I couldn't get the lap top or my desktop computer to recognize it was connected. This is where I ran the lm-1 analog out thru the EIO into the lap by USB. It's possible the analog out cable is acting funny. I might try and rig up a 3.5mm stereo wire like I've seen mentioned here before.
Thanks for your help guys.
