I was looking at the Wide Band AFR 1 LM1 pid calculation that shows AFR = (EXT.AD1*10) and would like to know how you go about changing this calculation if you want to output the AFR from the 1 to 5 volt range? The above calculation covers a narrow range of input voltage and I would think it would be better to cover a 1 to 5V range instead in order to be more precise. There's no problem in programming the LM1 to output AFR based on the 1 to 5V scale. If anyone has done this I'd like to hear from you.

Thanks,
