INPUT ACCESSORY GUIDE
Map- The PCV has the ability to hold two different
base maps. You can switch on the fly between
these two base maps when you connect
a switch to the MAP inputs. You can use
any open/close type switch. The polarity of
the wires is not important. When using the
Autotune kit, one position will hold a base map
and the other position will let you activate the
learning mode. When the switch is “CLOSED”
Autotune will be activated.
Shifter- Not used for snowmobiles.
Speed- If your application has a speed sensor then
you can tap into the signal side of the sensor
and run a wire into this input. This will allow
you to calculate gear position in the Control
Center Software. Once gear position is setup
you can alter your map based on gear position
and setup gear dependent kill times when
using a quickshifter.
Analog- This input is for a 0-5v signal such as
engine temp, boost, etc. Once this input
is established you can alter your fuel curve
based on this input in the control center
software.
Crank- Do NOT connect anything to this port unless
instructed to do so by Dynojet. It is used to
transfer crank trigger data from one module to
another.
ACCESSORY INPUTS
PCV Wire Connections
1. Remove the rubber plug on the backside of the
unit and loosen the screw for the corresponding
input.
2. Using a 22-24 gauge wire, strip about 10mm
from its end.
3. Push the wire into the hole of the PCV until it
stops and then tighten the screw.
4. Make sure to reinstall the rubber plug.
Note: If you tin the wires with solder it will make
inserting them easier.

1 Release the straps securing the side panels as shown in Figure A.
2 Remove the front cover as shown in Figure B.
3 With the side panels open and front covers removed, loosen the necessary
bolts on the airbox to lift the air box and headlight assembly off of the engine.
Leave the airbox and headlight on the sled, but lift it off the cylinder head and
prop it up with a 2x4 to allow access to the injector connectors as shown in
Figure C.

EFI Tuning with PCV
The Power Commander makes fueling changes off of the numbers in the map stored in the Power Commander. The snowmobile Power Commanders
are shipped with a Zero Map. With a Zero Map, the snowmobile will run the stock fueling programmed in the ECU. When a map is loaded into the
Power Commander, the snowmobile will be fueled according to the numbers in the map. The Power Commander does not make changes to the ECU
programming.
The numbers in the Power Commander map add or subtract a percentage of the fuel the ECU is supplying for a particular load condition. For example,
if the Power Commander map shows a 10 in a given cell, the Power Commander increases the amount of fuel the ECU is supplying by 10%. If the
Power Commander map shows a -10 in a given cell, the Power Commander reduces the amount of fuel the ECU is supplying by 10%.
When tuning, always start with a setting where the motor runs rich. Slowly trim fuel out to find the desired exhaust gas temperature (EGT) or air-to-fuel
ratio (A/F).
The PCV gives you the freedom to subtract up to 99% and add up to 250% of the fuel the ECU is supplying for a particular condition. When adding
fuel with the Power Commander, the injector duty cycle may reach 100% (always open) before the Power Commander value reaches 100%. For
example, if the ECU is running the injectors at 67% duty cycle (injectors open 67% of the time) then adding 50% fuel with the Power Commander will
max out the injectors. In this case, the amount of fuel that can be added will be limited by the injectors.
Fuel Subtraction
The PCV gives you the ability to trim fuel out of the map to correct rich conditions.
Caution: Engine failure can result from running the engine in a lean state.
