help with my lm1 I just bought an lm1 and i cant make it work in the afr histogram. I have gone in the pid section and selected lm1, but it still wont work. Is there something else im suppose to do? Any help would be awsome.
It isn't a plug in and it will work type of deal. All I can do is assume if you have EFI-Live. If you have HPTuners I hope someone else will jump in and help you.
Use these PIDs
Wide Band AFR 1 - LC-1 {CALC.AFR_LC11}
Base Efficiency Numerator 1 - LC-1 {CALC.BEN_LC11}
EXT.AD1
You must set up the LM1 with a computer. Period.
Set up 0 Volts to be 7.35 AFR.
Set up 5 Volts to be 22.35 AFR.
I got these numbers from the fact that EFI-Live uses this equation to calculate the AFR.
AFR = ({EXT.AD1}*3)+7.35
The Red wire I believe is channel one and the White Wire is channel two.
If I remember right, the LM1 doesn't accept those exact values so I made a custom PID. The custom PID will help get a more accurate reading for you AutoVE process.
Let us know how this works for you.

The LM1 is factory programmed to mimic a NB O2 sensor.
What you need to do is set up the LM1 to match the linear equation which it uses. Go to where it describes your PID for the LM1. Find out what that equation is and program your LM1 to match those characteristics. I believe that is your problem and if not a great place to start.
For example:
AFR = ({EXT.AD1}*3)+7.35
You know that the LM1 puts out 0-5Vs. If that abouve was your equation you would just plug 0 and 5 in there to get the AFRs you should program the LM1 to have at 0 and 5 volts.
Hopefully, someone will jump in to help you further.
