Need advice on wideband calibration

[stroker97k1500]

I have installed a LC-1 wideband 02 sensor and it works properly with the software that came with the sensor.
I have read conflicting instructions as to setting up the analog output settings to work with efilive.
the LC-1 tool says it's factory programmed the ext output #2 to have 0v=7.35AFR and 5.0v+22.39AFR
EFIlive gives this calibration in a txt file:
# Innovate LC-1 WBO2
# ========================
*CLC-00-932
V .................... 0.0..............5.0.........(.1) "{EXT.AD1}" ...............................so 0v=10.0 AFR?
AFR ................... 10.0............20.0.......(.2) "({EXT.AD1}*3)+7.35" ..................and 5v=20.0 AFR?
*CLC-00-933
factor................... 0.0...............2.0........(.1) "{CALC.AFR_LC11.AFR}/{GM.AFR}"

*CLC-00-934
V..........................0.0...............5.0.. ......(.1) "{EXT.AD2}"
AFR......................10.0..............20.0... ...(.2) "({EXT.AD2}*3)+7.35"
*CLC-00-935
factor....................0.0...............2.0... .....(.1) "{CALC.AFR_LC12.AFR}/{GM.AFR}"
=================================================
Then in the efilive tutorial for setting up the LC-1 is says to program 1V=10.00AFR and 2V=20.00AFR
I don't really know what voltage input it really wants it looks to my that it is conflicting itself.
Has anyone else ran into that before? Or am I just missing something?

leave the efilive text alone and use the lm programmer software
to set your analog outs.
using analog #1(yellow wire)
1. Connect the PC’s serial connection to the serial OUT of the LC-1. The terminator plug should be connected to the serial IN of the LC-1.
2. Turn the ignition switch ON to power the LC-1.
3. Open LM-1 Programmer.
4. Select the “Analog Out 1” tab.
5. Select “use air-fuel-ratio” option.
6. Set the Analog Out 1 to the following:
a. 0.88333 Volts at AFR: 10.00
b. 4.21667 Volts at AFR: 20.00
here is the link to the tutorial

Thank you!:master:
I should have kept reading on that tutorial... I got stumped and it makes much more sense to me now.

Dont forget you'll need to calibrate the V2's analog inputs for the ground offset of the LC-1. This will fix the problem of having any kind of split between the LC-1 digital out reading (as seen in the logworks program) and what EFI Live says the A/F is.

I hope this doesn't sound like a dumb question, but is there any explanation of the proper way to do this. My wideband reading in efilive IS different than the logworks2. The settings where I put:
a. 0.88333 Volts at AFR: 10.00
b. 4.21667 Volts at AFR: 20.00
is this what needs to be changed?
Thanks for the suggestion,

Robby,

Are you using V1 or V2? If V1 you need to change the CLC
({EXT.AD1}*3)+7.35 if it is reading high(example 15.7:1 instead of 14.7:1)

Then you would change the CLC to ({EXT.AD1}*3)+6.35

At least that is how I was told to do it in V1. Someone please correct me if I am wrong!

make sure the LC1 is set for GASOLINE/DIESEL ect.
which ever one you are using.
a free air calibration of the WBO2 and a calibration
of the V1/V2 AD outs would also be a good idea.

[stroker97k1500]

Mark I am using the flash scan v2.
I know its set for gasoline and AFR under the external output settings.
I am not familiar at all on these changes:

"CLC ({EXT.AD1}*3)+7.35 if it is reading high(example 15.7:1 instead of 14.7:1) Then you would change the CLC to ({EXT.AD1}*3)+6.35 "

I guess I am a real noooob here when it comes to this since I have not seen it done before and just going by what I read on here and the tutorials.

Thanks for your time and suggestions guys, I will try to figure out how to do this somehow, it just might take me one time and patience

I think there is something weird going on with my tune when the MAF was disabled for speed density the motor wont even run. I uploaded the ve for your 383 in my talbes and it would idle but wont rev at all. I can switch back to the sock 350 tune and drive it around. I will change around with the maf p0101-p0103 settings to see if this changes anything. with 15-20% added to your ve table it runs at 22-35:1 AFR in gray #'s on the log works, and this is after re-setting the lc-1 and free air calculation with the o2 sensor removed from the pipe.

This is a FAQ for wideband adjustments on the V2. I have V1 so cant help you much on setting a wideband on V2.

Thanks To all for the suggestions.
I will have to wait for a while to get back to tuning In the mean time I will continue reading. My 383 ate the distributor gear off...:bawl: but on the good side at least it wasn't the pistons or anything internal breaking.
