A quick photo to help the other rockies (like me) getting an LM1 connected to the MPVI Pro.

I'm still working on getting the same reading between the two, but I am making progress. At WOT, the LM1 was reading 12.3 - 12.4 and HP Scanner showed 12.0 - 12.1. I'll study more on how to setup a PID to match the 0 volt:10 AFR to 5 volt:20 AFR slope that I programmed in the LM1
I only have the white and copper wires plugged in the green connector. Any reason I should connect the red one as well?
Not really, I just have the white to the #1 and the red isn't connected to anything.Quote:

guess you could defeat that with maybe a custom PID but i personally CBF'ed goin to those lengths when its really WB ya after.
I have mine connected like this also. I have not used it yet but have a few questions about its use. This may or may not be the right section for this so feel free to move it if necessary.
Is the installation of the wideband as simple as setting up the LM-1, connecting to the interface and putting the wideband in the exhaust bung where the narrow band was removed? When the wideband is installed in place of the narrow band and connected to the interface, what is telling the PCM to add or subtract fuel in place of the missing narrow band?
Newbie questions I know but I am ready to use both the LM-1 and the HP Tuners to get my 70 corvette on the right path.
Eddie - I installed the LM-1 wideband in the rear O2 sensor bung on my 99 Corvette, leaving both narrow band O2 sensors in place. There are some write ups on how to setup the Innovative wideband O2 as both a wide and narrow sensor. You will have to go that route or add a 3rd bung to your exhaust.
Thanks for the tip but I do not have rear bungs so I will have to use it in one of the front bungs. Most of the write ups I have seen address the LC1 and how it is connected to the MVPI.
Not really wanting to run out and get another bung welded in.
Hmmm....I don't have a white wire on my LM1(white casing, not black). I have black, purple, blue, green, orange, red, and brown.
Which wires do I use?
Thanks,
Norm
This is your Analog out wiring harness? It should only have the 3 wires above.Quote:

Brown is bare copper and the ground. Yes it should be hooked up. I hooked red up just so it is not a loose wire hanging around to short on anything.
what pin out did you hook it up to
red? input 2.
Great thanks again, I am going to put the white on #1 Red on #2 and the Ground to 5 or 6
