Dakota Digital 3 operation manual Fuel sensor setup Sender

Fuel sensor setup (SENDER)

This menu is used to select the fuel level sensor type. The table above 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”

∙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

∙When “CUSTOM” is displayed press and release the switch.

∙The speed display will show the current sender resistance as read by the control box.

∙The message display will show “SET 00”. Move the float to the empty position and then press and release the switch.

∙The message display will show “SET 33”. Release the switch and move the float to 1/3 full and then press and release the switch.

∙The message display will show “SET 66”. Release the switch and move the float to 2/3 full and then press and release the switch.

∙The message display will show “SET 99”. Release the switch and move the float to the full position and then press and release the switch. The new sender is now stored under the

“CUSTOM” sender selection.

∙The message display will be back in the fuel sub-menu showing “TEST”.

***If the resistances recorded during custom calibration are not in sequence you will get a “ FAIL” message at the end of calibration. No values will be saved and calibration must be started again. Make sure the resistance of the sensor is linear from empty to full.

Note: Once the custom sender is programmed, go back and ensure that “ CUSTOM” is selected in the “ SENDER” menu. Programming the custom sender curve does not automatically make it the ‘active’ sender.

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 troubles or feel that the reading is incorrect. You can use the table of fuel sensors above to get an idea on 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.
