LM-1 and HPTuners I need some help on getting these two to work together. My LM-1 display is reading 14.6AFR at idle and my histogram is reporting 11.1AFR. I have the cell under Intake Air Temp (Input 1) allocated for the LM-1 and my connections to the EIO are as follows:
EIO LM-1
white>>>>red (Analog 1)
black>>>>ground (bare)
If I use the white wire on the LM-1 (analog 2) the readings are closer. The LM-1 display will read 14.6 and the histo reports 13.1. I must be missing some kind of configuration step somewhere. Anyone have these two reporting the exact same values simultaneously? Thanks for any help

did you configure your LM-1 for the correct output? You need to use the LM-1 software and the serial cable it comes with to change output 1 to be
0 volts: 10:1 AFR
5 bolts: 20:1 AFR
then it should display properly
0 volts: 10:1 AFR
5 bolts: 20:1 AFR

Thanks horist, I got it working. I'm not sure if it makes any difference but the LM-1 Programmer would only let me enter 0V = 10AFR and 4.996 = 19.994AFR. I tried to enter 5V = 20AFR but it automatically reverted back. Should be OK though.
