NOTE:
The Suzuki Engine Interface Device Configuration menu contains
two Engine Trim calibration commands, which will be addressed in
the next segment of this section, Calibrating EP Sensors.
Calibrating EP Sensors
The factory calibration settings for the EP-10 Fuel Flow, EP-15 Fluid
Level and Suzuki Engine Interface should be adequate for the majority
of applications, so calibration will not be necessary in most cases.
EP-10 Fuel Flow Calibration
The default calibration for the EP-10 Fuel Flow is adequate in most
cases, but if Fuel Used readings are off by more than 3 percent, calibra-
tion is recommended.
To check fuel flow accuracy:
Select Fuel Used to be shown as Overlay Data on your unit's main dis-
play. Refer to the Overlay Data segment of this manual for instructions
on how to select Fuel Used data as Overlay Data.
1. After selecting Fuel Used as overlay data, fill up your tank and press

8. Take your vessel out on the water and burn at least five gallons of
fuel. Be sure you run only ONE engine — the engine connected
to your fuel flow.
9. Fill up your tank again, noting how much fuel you added to the tank.
Compare that number to the Fuel Used figure displayed on the page
you customized. If the amount of fuel you added to the tank and the
fuel used figure are off by more than 3 percent, we recommend the fuel
flow be calibrated.
NOTE:
You must use the gauge's Fill Tank command when filling your fuel
tank to keep the fuel flow updated with correct information on the
amount of fuel in the tank.
