Microtech + LC-1 wideband = ?

Thats the ?. I am running an LT8s configured for wideband, I also have an LC-1 from Innovative motorsports. When configuring the AFR gauge you must program the LC-1

3) Set analog output 1 as follows:
a. Select the “air fuel ratio” button
b. 1.000V= 10.00 a/f
c. 2.000V= 20.00 a/f
d. Select “advanced” button
e. Select the “Instant” sample rate.
f. Enter 0.00V at warm up.
g. Enter 5.00V at output error.
h. Press “OK”
i. Press the program Button. It takes one second to program,
you will not get any message about programming completed
but you will notice that the program button is now shaded.
This confirms that you have programmed the LC-1.
j. You are done! NOW REMOVE THE TERMINATOR
PLUG FROM THE “IN” CONNECTOR!

WHAT ARE THE values for b, c, f and g when programming the 2nd output to the LT8s? If I use the same values above for both outputs my AFR gauge and the Microtech give 2 different readings with the Microtech being a point higher.

PLEASE HELP!

i don't think the lt8 was available with wideband option. i thought only 10-12 could get it.
i think what you are trying to do is use the LC-1's analog output 2 to send a 0-1 volt signal to get an air fuel reading. i was trying to do that as well and i read that all you have to do is alter "b"+"c" so it fits in that range. i tried but at idle my wideband reads 12.5-13.0 at idle but on the microtech it reads 11.0 and never fluctuates.

Its an upgraded LT8s, Microtech no longer upgrades the LT8 as they want people to buy the 10-12. The wide band reading works its just off because I don't have the proper values. It will follow the output to the gauge throught the entire range just 1 point off. We have been tuning it like this, datalogging it and making adjustments knowing it a point high. We just want to be precise.

We havent datalogged to compare but yeah. At idle my gauge shows 13.2 the MT shows 14.4. Pretty much the same under load as well.

What values do you programme the LC1 to give you the readouts?
