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.
LO 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.
MD This adjustment is for Medium (mid-range) load conditions. This will affect throttle settings from
approximately 1/3 up to 2/3.
HI 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.
Note 2: It is possible to max the injector (duty cycle > 100%) before the adjustment setting is maxed! Pay careful
attention to EGT’s, O2 readings, and fuel pressure when running with engine mods that require a lot of additional
fuel!
tr
This adjustment is to Trim the PTO cylinder (left-side cylinder when sitting on the sled). This is used to add
or subtract fuel on the left side if fine-tuning is desired. The LO adjustment is not affected by the Trim value –
trim is only used for the MD and HI settings. It is best to tune the right (mag) cylinder first then make
adjustments to the left (PTO) cylinder if necessary. If more than a small amount of adjustment is required
(greater than plus or minus 7), check for other problems first (such as incorrect harness connections to the PTO
cylinder).

This menu adjusts the fuel according to the pressure transducer. Fuel can be added or subtracted as follows:
-4: fuel adjustment when pressure is below -2 in Hg (normal idle)
-2: fuel adjustment when pressure is between -2 and 0 in Hg
+4: fuel adjustment is centered at 4 psi. If pressure is below 4, fuel is blended with -2 setting. If pressure is above 4,
fuel is blended with +8 setting.
+8: fuel adjustment is centered at 8 psi. If pressure is below 8, fuel is blended with 4 setting. If pressure is above 8,
fuel is blended with 12 setting.
Screen 7 (Turbo High Boost)
M1U 12 16 20 24

12: fuel adjustment is centered at 12 psi. If pressure is below 12, fuel is blended with 8 setting. If pressure is above
12, fuel is blended with 16 setting.
