Hello Eugenio Balam,
Regards to Analog Expander, the existing fuel sender can send fuel value in 3 different ways, they are:
1. Resistve Value
2. Analog Volt based on Positive
3. Analog Volt based on Negative/Ground
Please confirm if Analog Expander can support all the above method.
FYI I have 2 Analog Expander but they can’t read the Resistive value. I can read the Resistive value using multimeter.
