Hello gentlemen. I am new to wideband 02 sensors and the holley 950 in my car. I have the LC1 brown wire 0-5v signal going into the 950 commander. The problem Im having is that I downloaded the holley base map and when you use the wideband setting I dont think that the afr and voltages are the same as the Innovate
wideband. I called Innovate and they told me its a linear ouput 0 volts= 7:35 afr (rich) / 5 volts= 22:39 (lean) how do I calculate what the afr's and voltages are between these settings, theres like 10 settings in the map that must be entered. I need to program these into the map for the wideband and computer to work correctly. I hope this isnt too confusing! I hope somebody who has the holley commander and lc1 wideband knows what I'm talking about!

Thanks a Bunch!! Thats why I use this forum. I always get an answer-- SWEET! I take it the LC1 is programmed just like the LM1, you got the LC1 correct? Putting in those correct values should make a tremendous difference in tuning correctly. I was going off what the base map was set at, not even knowing.. ( lol)
Thanks again. I have another question that you might be able to answer. I really want to use a wideband gauge as well. But I know that the brown wire which is the 0-5v is already wired into the 950. The yellow wire is the 0-1v signal used for narrow band, correct? This is currently unused. I was just on the innovate site and I see that you need to use the 0-5v signal also on the gauge. Is it safe to hack into that wire to get my signal to the gauge also. I see you got a gauge is that how you wired it? I thought that I could use the 0-1v signal wire for the gauge?
lc1 is programmable. has a serial cable and a little software package that comes with it. you can reprogram the other output to be a 0-5v signal like the gauge expects.

I have the XD-16 gauge and I connected it to the LC-1 by:
Quote:
If connecting to an LC-1 or LMA-3, connect the male to male 2.5mm Stereo cable between the Serial OUT port of the LC-1 or the LMA-3 to the Serial IN port of the XD-1.
