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.
If you tin the wires with solder it will
make inserting them easier.

The PCV has the ability to hold two different
base maps. You can switch on the fly between
these two base maps when you hook up 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.
Not used for snowmobiles.
If your application has a speed sensor, 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.
Harley Davidson models have this feature
enabled internally—do use this input for
HD models.
Note:
NOT
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.
Do 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.

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.
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.
