The fuel adjustment rpm ranges are blended as shown in the picture above. This allows for a broader range of adjustments
with fewer steps. Each fuel setting is centered at a particular rpm value, in this example: 3000, 5000, 6700, 7800, 8100rpm.
Each region is blended with the region below and the region above it as shown. For example, if the rpm is at 4000, the
adjustment value will be half the value of the 3000 setting plus half the value of the 5000 setting.

M1L

This displays current map that is being used – in this case, M1 stands for Map1. Five possible fuel maps can

be used. Each map consists of all your configuration and fuel settings for a particular setup. The “L”
indicates that this map is Locked – this means the settings cannot be changed (the up/down buttons have no
effect). If the map is Unlocked, adjustments can be made to any setting and these changes will be
automatically saved to the selected map. Refer to the Load/Copy sections for more details about how to lock
and unlock individual maps.

3000

This is the RPM Region for the fuel adjustments on this screen. For this example, this screen’s adjustments

will be centered at 3000rpm. There are usually 5rpm regions (some boxes with special programming will have
additional regions). The effect of the 3000rpm setting tapers off until 5000rpm as shown in the picture above,
while the effect of the 5000rpm setting is ramping up. The other regions work similar to this.

(3000 RPM screen only) This adjustment is for Idle (0-2400 rpms). The 3000 LO setting will take over above

2400 rpms.

This adjustment is for Low load conditions. This will affect throttle settings from approximately 0 up to 1/3.

For rpm region 3000, this adjustment will affect idle. For other rpm regions, this will affect deceleration and
light-load cruising conditions.

This adjustment is for Medium (mid-range) load conditions. This will affect throttle settings from

approximately 1/3 up to 2/3.

This adjustment is for High load conditions. This will affect throttle settings from approximately 2/3 to full

open.

Note 1: Each number is equal to about 1/2% of the total available fuel. The maximum available fuel will vary
with each engine as well as with elevation and air temperature.
