INPUT ACCESSORY GUIDE
Map - (Input 1 or 2) The PCV has the ability to hold
2 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. (Set to Switch
Input #1 by default.)
Shifter- (Input 1 or 2) These inputs are for use with the
Dynojet quickshifter. Insert the wires from the
Dynojet quickshifter into the SHIFTER inputs.
The polarity of the wires is not important. (Set
to Switch Input #2 by default.) This option
does not apply to watercraft.
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. This option does not
apply to watercraft.
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
Wire connections:
To input wires into the PCV first remove the rubber
plug on the backside of the unit and loosen the
screw for the corresponding input. Using a 22-24
gauge wire strip about 10mm from its end. Push the
wire into the hole of the PCV until is stops and then
tighten the screw. Make sure to reinstall the rubber
plug.
NOTE: If you tin the wires with solder it will make
inserting them easier.

1 Remove the seat to access the watercraft’s engine compartment.
2 Locate and unplug the stock wiring harness from the engine’s fuel injectors
(Fig. A).
The injectors are numbered from front to rear.
3 Plug the PCV wiring harness in-line of the fuel injectors and the stock wiring
harness (Fig. B).
The PCV connectors with ORANGE colored wires should go to injector #1.
The PCV connectors with YELLOW colored wires should go to injector #2.
The PCV connectors with GREEN colored wires should go to injector #3.
The PCV connectors with BLUE colored wires should go to injector #4.

4 Locate and unplug the stock wiring harness from the MAP sensor (Fig. C).
The MAP sensor is on the intake manifold between injector #3 & #4.

6 Secure the ground wire of the PCV wiring harness to the bolt pictured in
Figure E.
This bolt is on the bracket at the front of the engine.

7 Locate and unplug the stock connectors for the Crank Position Sensor (Fig. F).
This connector is by the #2 fuel injector.

5 Plug the PCV wiring harness in-line of the MAP sensor and the stock wiring
harness (Fig. D).
The PCV MAP sensor connectors are the 3-pin connectors that have the solid
BROWN wires going to them.

8 Plug the 2-pin connectors from the PCV wiring harness in-line of the stock
Crank Position Sensor connectors (Fig. G).
9 Locate and unplug the stock wiring harness connector from the Throttle
Position Sensor (Fig. H).
The TPS does not have sufficient accessibility for a picture and is difficult to
access. The Throttle Body is located towards the rear of the engine. The TPS
is located on the Throttle Body at the opposite side as the throttle cable pulley
shown here (Fig. H).
10 Plug the PCV wiring harness in-line of the stock wiring harness and Throttle
Position Sensor.
FIG.H
11 Use the supplied zip ties to secure the PCV wiring harness to the locations
shown on the fuel rail such that it is clear as possible of any hot or moving
parts (Fig. I).

FIG.J
Bypassing the PCV
In the event you need to run the engine without the PCV module, the supplied
bypass plug will return the engine control and tune back to stock. Refer to Fig.
K.
1 Unplug the wiring harness from the PCV Module.
2 Plug the bypass plug into the PCV wiring harness in place of the module.
FIG.K
12 Using the supplied 3M Dual Lock fastening strips, secure the PCV module to
a suitable mounting location. We recommend and use the location shown in
Fig. J on the hull in the forward right area of the engine compartment, but your
location may vary depending on watercraft model and other considerations.
Keep the module as high in the hull as possible. Use the supplied alcohol
swab to clean the surface area prior to applying the 3M Dual Lock strips.
13 Plug the PCV module to the PCV wiring harness and plug the supplied CAN
termination plug into one of the expansion ports on the PCV module. Cover
any remaining open ports and the wire terminal strip clamping screws on the
back of the module with the supplied rubber plugs.
The picture in Figure J was taken with the optional Ignition Module accessory
installed. If you are not using the Ignition Module accessory, the additional
WHITE 3-pin connector on the PCV wiring harness does not need to be
connected to anything and the supplied Crank Data Port Plug (WHITE 3-pin
mating plug) should be installed to it to prevent corrosion..

The PCV Control Center software allows you to enable and configure Auto-tuning
when it sees one of these devices connected.
Refer to the appropriate Wideband device installation guide for more information on
installation.
Refer to the PCV Control Center Help for more information on enabling and
configuring Auto-tune.
FIG.M
Connecting the PCV to the Wideband
1 Verify the Wideband device is installed correctly. Refer to the appropriate
Wideband device installation guide.
2 Connect the PCV to the Wideband device using the CAN to CAN cable. Refer
to Figure J or K.
The CAN to CAN cable is provided with the Wideband device.
3 In one of the open CAN ports on either AutoTune module, attach the provided
CAN termination plug. Refer to Figures L, M, and N.
FIG.N
Using Auto-tune with PCV
To take advantage of Dynojet’s AutoTune feature with the PCV, you need to install a
Wideband device on your vessel. With the PCV, this could be one of the following:
•Wideband 2—single channel Auto-tune module with gauge output
•AT-200—single channel AutoTune only module (shown in Figure M)

EFI Tuning with PCV
The PCV makes fueling changes based off of the values in the map stored in the PCV.
The PCV is shipped with a Zero Map. A Zero Map means that all the values are 0, which will yield no changes and the watercraft
will run exactly the same as if the unit were not installed.
When a map is loaded into the PCV, the engine fueling will be adjusted according to the values in the map.
The PCV does not make changes to the ECU programming. The numbers in the PCV map add or subtract a percentage of the fuel
the ECU is supplying for a particular load condition. For example, if the PCV map shows a 10 in a given cell, the PCV increases
the amount of fuel the ECU is supplying by 10%. If the PCV map shows a -10 in a given cell, the PCV 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 PCV, the injector duty cycle may reach 100% (always open) before the PCV fuel change 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 PCV will max out the injectors. In this case, the amount of fuel that can be added will be limited by the injectors.
Primarily, tuners will choose to map the fueling based off of a throttle position versus RPM fuel table; however, the device has the
capability to map fueling based off of intake manifold air pressure versus RPM as well.
