To adjust the MAP, hold both the STEP and LF buttons simultaneously for five seconds,
which will proceed to the next step. Otherwise the next step will be skipped.

37.1.1 Programming the Horsepower Constant
You must adjust the HP Constant once for your aircraft. You must perform this adjustment in the air while the aircraft is
in flight between 5,000 and 8,000 feet MSL.
1. Enter the pilot program mode by simultaneously holding the STEP and LF buttons for five seconds.
2. Tap STEP repeatedly until you see—for example— HIP = I25. Then hold both the STEP and LF buttons display
until you see ADJUST, followed by HIP= I25. The adjustment range for the HP Constant is 45 to 180.
3. Set the MP and RPM per your POH to 70 percent power. Let conditions stabilize.
4. Change the HP reading on the EDM-960 to 70 percent by adjusting the HP constant in the lower display by holding
or tapping the LF button. Percent HP should be close to 100 percent during takeoff at sea level or you can set it at
take-off ,100 ft into the roll.
5. Tap the STEP button to proceed to the next step.
Fine tuning the MAP gauge
Sets the manifold pressure calibration .
You may need to correct the MAP based on the altimeter setting at a sea level airport.
1. Enter the pilot program mode by simultaneously holding the Step and LF buttons for five seconds.
2. Tap Step/OK repeatedly until you see—for example— HPConstant=125. Then hold both the first two buttons
Step/OK and Change buttons display until you see Adjust, followed by HP Constant=125.
3. Again, Hold both the two buttons, Step/OK and Change buttons display until you see ADJUST, followed by
MAP+0. The adjustment range for the MAP is ±2.0 in Hg. As you adjust the MAP up or down you will see a
change in the MAP gage under RPM. When you see the correct setting stop.
4. Tap the Step/OK button to proceed to the next step or hold both buttons again to exit setup.
Do this one time and only if the MAP on your manifold pressure gauge doesn't match the MAP shown on the EDM-960
You must do this on the ground with the engine turned off.
