I have V2 V7.5.6. I am having trouble getting my external voltage to log in my scan software. It has worked before, the calculations are correct in the sae generic file. I used a volt meter to check voltage at the orange connector at the interface and I have 5 volts there with engine not running. So I know the LM1 is sending the voltage, and I know the interface is getting the voltage, but when I log the PID's EXT.AD1 the voltage just sits there at zero.

Here is the calculations I have in the sae_generic file:

# Innovate LM-1 WBO2
# ========================
*CLC-00-928
V 0.0 5.0 .1 "{EXT.AD1}"
AFR 10.0 20.0 .1 "({EXT.AD1}*2)+10"
*CLC-00-929
factor 0.0 2.0 .1 "{CALC.AFR_LM11.AFR}/{GM.AFR}"
*CLC-00-930
V 0.0 5.0 .1 "{EXT.AD2}"
AFR 10.0 20.0 .1 "({EXT.AD2}*2)+10"
*CLC-00-931
factor 0.0 2.0 .1 "{CALC.AFR_LM12.AFR}/{GM.AFR}"

I have the firmware set in the LM1 to be 0 volts = 10AFR and 5 volts = 20AFR....which matches the sae_generic file.

As I said, the last time I tuned everything it was fine and but now it's not. I plan to get the serial cable soon but I simply need to get this tune done ASAP.

Please help!
