Possibly the 30-0300 can be used with any ADX, with the correct conversion?

Information from the link in post #2:

For the LC-1 WideBand 0V = 7.35 AFR and 5V = 22.39 AFR.
AFR of 7.35 to 22.39...

The attached .pdf does not show that the 30-0300 has a programable AFR range.

The attached .pdf shows the 30-0300 has an AFR range of 8.0 : 1 ~ 20.0 : 1
