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 Remove both side panels by pulling out the split cotter pins and pivoting the
panels rearward out of the hinge points.
2 With the side panels removed, remove the torx head screw securing the hood
to the cowling on both sides of the snowmobile.
3 Unscrew the two torx screws underneath the front of the snowmobile.
These screws are recessed above the skid plate and accessible through two
access holes.

9 Pull rearward on the cowling allowing the tank shroud to pop loose above it.
10 Lift the tank shroud off the gas filler neck taking care to unplug the spade
connectors for the reverse beeper.
11 Using the supplied velcro, secure the PCV to the top of the stock ECU as
shown in Figure H.
Make sure to clean both surfaces with the alcohol swab before attaching.
12 Allowing the wire harness to loop rearward on the machine and then come
forward, route the injector leg of the harness down the left side of the engine
on top of the clutch guard as shown in Figure H.
13 Locate and unplug the 6-pin connector on top of the clutch guard as shown in
Figure I.

14 Attach the injector connector from the PCV harness to the stock injector
connectors as shown in Figure J.
Verify these connections are pushed down amongst the stock harness so the
side panel cooling vent can be slid over the top into its factory location.
15 Remove the fuse box cover on top of the clutch guard. This allows access to
the nut shown in Figure K.
16 Remove the nut.
17 Attach the ground lug from the PCV harness to the bolt.
18 Retighten the nut.
19 Route the other leg of the of the harness upward near the intake manifold.
20 Locate and unplug the TPS sensor.

21 Attach the TPS connector from the PCV harness to the stock TPS connectors.
22 Locate the MAP sensor connector.
The MAP sensor connector is located on the
manifold slightly rearward of the TPS connector.
23 Using the supplied posi-tap, attach the grey/white
wire from the PCV harness to the green/tan wire
on the stock MAP sensor.
24 Route the last leg of the PCV harness up and over the intake manifold to the
right hand side of the snowmobile.
25 Unplug the 2-pin crank sensor connector.
This connector is located inward of the exhaust silencer along the engine.

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.

Additional Features and Accessories for the Power Commander V
The PCV can be combined with the Dynojet Autotune kit (P/N AT-200) allowing you
to tune as you ride. The Autotune feature uses a target AFR table where the user
specifies a target AFR based on TP and RPM. After enabling Autotune, the user
rides as normal and the PCV calculates a trim table as you ride. Once the system
has calculated a trim table for the specified conditions, the user can accept the trims
as a base map and turn the Autotune feature off.
Autotune is a very powerful feature allowing the user to build custom maps for
any modifications made to the sled, including big bore kits, aftermarket pipes, and
intakes. The Autotune kit may also be used to smooth out a stock sleds fuel map
eliminating midrange flat spots and improving throttle response.
If you are looking for a display for your setup we have the answer. Dynojet’s LCD-
200 is a color touch screen display capable of displaying all PC data and AFR if you
are using the Wideband 2. The LCD-200 is capable of logging data including TP,
RPM, Injector duty cycle, fuel change, AFR, and two analog signals input into the
PCV.
The LCD-200 uses a standard SD card (1GB or smaller) to store data. The data
logged on the LCD-200 can be played back in the field or downloaded to your
computer and viewed in Excel.
