BoostMAX willwill increase the power output of your 3.5L Ecoboost vehicle. BoostMAX has been designed to be mounted with plastic zip ties near the OEM ECU. The wiring harness plugs into two sensors on the engine and then runs into the vehicle cabin through  a drivers side firewall hole and connects to the pedal sensor. 


Reasons to choose BoostMAX!


The concept behind BoostMAX:

• Add additional horsepower without reprogramming the ECU.
• BoostMAX connects to the MAP, TIP and Pedal Position sensors via a plug & play harness.
• Remote boost knob allows the user to add up to 5psi of additional boost (on the fly).
• 3.5L Ecoboost customers have reported gaining 90 rwhp on an otherwise stock F150 with just a JMS BoostMAX.

• Add additional boost "on the fly" and when you want it.
• Use the remote boost knob to"dial-in" additional boost.
• Replace the remote boost knob with the Red Chip: 87 octane boost curve.
• Or remove the remote knob and red chip and enjoy the optimized 93 octane boost curve.

• Simple to install, Plug and Play design that installs in just minutes.
• Plug and Play for 2010-2015 Ford Ecoboost vehicles.


STEP 1
• Ignition key off, remove key from ignition.
• Open the vehicle's hood.
• Disconnect the negative battery terminal.
• Remove the engine oil fill cap
• Remove the plastic engine cover and set aside
• Replace the engine oil fill cap


STEP 2
• Locate the MAP Sensor (on top of the manifold)
• Disconnect the OE MAP Sensor connector from the MAP sensor.
• Connect the BoostMAX Wire Harness Labeled "MAP Sensor" in-between the MAP Sensor and the
OE Connector.
• Use zip-ties to secure the MAP sensor wiring.


STEP 3
• Locate the TIP Sensor (directly in front of the throttle-body, integrated into the air-inlet tube)
• Disconnect the OE TIP Sensor connector from the TIP sensor.
• Connect the BoostMAX Wire Harness Labeled "TIP Sensor" in-between the TIP Sensor and the
OE Connector.
• Use zip-ties to secure the TIP sensor wiring.


STEP 4

• Connect the BoostMAX Module to the DB-25 connector, secure the screws with the screwdriver.
• Route the BoostMAX wiring harness alongside the factory ECU (located on the firewall).
• Use zip-ties to secure the BoostMAX Module near the factory ECU.


STEP 5
• Route the flat four pin wire harness across the back of the engine and pass it through the rubber firewall grommet. Route the four pin wire through the firewall grommet to the drivers side of the vehicle.
• Note: The firewall plug might be covered by insulation on the inside. It may help to attach the wire harness with tape to a stiff wire (coat hanger)
in order to fish it through the firewall opening (use two people).
• Use zip-ties to secure the wiring.


STEP 6
• Connect the Pedal Position Harness to the flat four
position main BoostMAX Harness (via flat four pin connector, left side connector in the picture)
• Choose between connecting the Pedal Position Harness to the Remote Boost Knob OR to the "87
Octane Red Chip". (Right side connector in picture)

Note: In the picture the Pedal Position harness in the center, the main harness plugs into the Pedal Harness and then the Remote Knob Plugs into the Pedal harness.


STEP 7
• Locate the Accelerator Pedal Position Sensor (Located on top of the Accelerator Pedal bracket)
• Disconnect the OE Pedal Position Sensor connector from the Pedal Position sensor (pull the red tab
out and then press the black tab to release).
• Connect the BoostMAX Wire Harness Labeled "Pedal Sensor" in-between the Pedal Position Sensor
and the OE Connector.
• Use zip-ties to secure the Pedal Position Sensor wiring.


STEP 8
• Mount the Remote Boost Knob: We recommend mounting via a single OE screw near the Brake Release
mechanism.
• Use zip-ties to secure the Remote Boost Knob wiring.
• Adjust the BoostKnob to the desired performance level:
• Recommended knob settings: 87 octane = 50%, 91 octane = 90%, 93 octane = 100%.


STEP 9
• Reconnect the negative battery terminal.
• Start and test the vehicle, it should function like normal with additional WOT power. If the Ignition
Key is "ON" the Green LED on the BoostMAX will illuminate ON.
• If the vehicle has a wrench light and no throttle: it is due to disconnecting the Pedal Position Sensor.
• Turn the vehicle off, remove the key, wait 30 seconds and restart the vehicle (the wrench light will
automatically clear itself on restart).
Enjoy the extra plug & play BoostMAX power.
