Fuel sensor setup (SENDER)
This menu is used to select the fuel level sensor type. The table, on previous page,
shows the seven options and resistance ranges as well as the custom option.
Note: You need to calibrate the custom sensor to your specific fuel sensor if you are
using this option in the custom setup in the steps below.
When "sender" is displayed, press and hold SW1 until you get " - "
Release SW1 and the current sensor selection will be displayed.
Press and release SW1 to scroll through the sensor options "GM 30" "GM 90" "GM 250"
"F 10" "F 150" "V 180" "SW 33" "CUSTOM" "BUS"
When the desired setting is displayed, press and hold SW1 until " - " "DONE" is displayed.
Release the switch to go onto the next menu item.
Custom fuel sender curve setup (CUSTOM)
You will need to have the sender out of the tank, or begin with the tank empty and
add fuel during the custom fuel sender setup.
*** The factory default custom curve is 110 empty and 5 ohms full

Fuel sensor test (TEST)
This menu will allow you to check the resistance the control box is reading from the fuel
level sensor. This can be used as a diagnostic tool if you are having trouble or feel that the
reading is incorrect. You can use the table of fuel sensors above to get an idea of the
resistance you should be seeing.
When "TEST" is displayed, press and hold SW1 until you get " - ".
Release SW1 and the current resistance from the fuel level sensor will be displayed on the
speedometer and "R fuel" is displayed on the odometer readout.
Press and release SW1 to scroll through the next sensor input if you wish "R TEMP" "V OIL"
"R FUEL".
Once complete, hold SW1 until " -" "DONE" is displayed.
Release the switch to go onto the next sub-menu item.
Note: Fuel level sensors are generally not precise; in the test function you should expect to see
some error. For instance a GM 0-90 sensor may display 5 ohms empty and 97 ohms full. If you
are within 10% of the values in the table, this is considered within specification.
