By installing the buyer confirms he/she has read, understood and accepted the Important information. Note In order to ensure maximum performance and safety, 91 octane fuel or greater must be used. The tuning box is programed with a warm up sequence that will not allow full performance to be reached until 10 min or after 3500 RPM is exceed. It's important to allow the vehicle's oil temperature to reach operating temperature before driving the vehicle aggressively. 2
Preparation for installation Do not start the installation when the ignition is on! 1. Switch off your vehicle! 2. Open the hood./bonnet 3. Lock all doors and close your vehicle. LOCK 1. Wait 5 minutes after locking!!! 2. Do not open any doors during this time. 3. During this time all sensors of the vehicle will switch off. 4. After the 5 minutes you can begin with the installation. 5 min Notes to be observed during the installation! When installing the wiring harness and the electronics, pay attention to the following: Do not mount near moving parts Mount the electronics in a place protected from water, vibration and high heat sources such as exhaust. 3
PREPARATION Preparation Remove the two engine access panels by pulling up on them carefully. These covers are only held in place by rubber grommets 4
PREPARATION Preparation Remove the remaining engine covers by loosing the T30 torx scews. To remove the side engine panel you must remove only the lower portion of the engine bay hatch strut.!!! Attention screws have different lengths.!!! 5
PREPARATION Preparation Remove the covers of the two air filter boxes on both sides. To do this loosen the hose clamps and disconnect the sensors. Then loosen all clips and carefully remove the covers of the air filter boxes. Images above are only for reference. All engine covers must be removed for install. 6
PREPARATION BOOST SENSOR #1 A BOOST SENSOR #2 D CAMSHAFT SENSOR C B MANIFOLD AIR PRESSURE SENSOR A: Boost pressure sensor 1* B: Manifold air pressure * C: Camshaft sensor * D: Boost pressure sensor 2* Images above are only for reference. All engine covers must be removed for install. 7 * Colors correspond to the marking on the wiring harness
INSTALLATION A. A. Boost pressure sensor 1 The boost sensor #1 (A) is located in the upper left corner of the engine compartment next to the intercooler. Unplug the factory 3-pin plug at the boost sensor #1 (A) and insert the supplied cable loom marked (A) in between. Make sure the connection is good. The connectors should click and lock into place. Removal of the intake pipe will provide better access to boost sensor #1 (A) 8
INSTALLATION A A. Boost pressure sensor 1 Additional image showing the location of the boost sensor #1 (A) 9
INSTALLATION D D. Boost pressure sensor 2 The boost pressure sensor #2 (B) is located at the top right side of the engine compartment, similar to the boost pressure sensor 1. Remove the three 10mm bolts and carefully move the ecu out of the way to provide better access to the boost sensor connector. You do not need to disconnect the ECU. Disconnect the 3-pin plug-in connection at the boost pressure sensor 2 and insert the supplied cable loom which is marked with (D) in between. Make sure the connection is good. The connectors should click and lock into place. 10
INSTALLATION C 11 C. Camshaft sensor The Camshaft Sensor (C) is located on the left side of the engine, slightly behind the throttle body. Disconnect the 3-pin plug-in connection at the camshaft sensor and insert the supplied cable loom which is marked with (C) in between. Make sure the connection is good. The connectors should click and lock into place.
INSTALLATION B B. Manifold air pressure sensor The Manifold Pressure Sensor is tucked under the aluminum shield, just in front of the engine cover. Disconnect the 3-pin plug-in connection at the manifold air pressure sensor and insert the supplied cable loom which is marked with (B) in between. Make sure the connection is good. The connectors should click and lock into place. 12
INSTALLATION Mount the tuning box and secure the wiring harness to the vehicle using cable ties and 3m double side tape. To allow easy access for switching out the Bridge Plug, we reccomend placing the tuning box near the air boxes. (SEE BELOW) Before reinstalling engine covers, start the car to verify all connections are good and that no check engine lights are present. END Function of the bridge plug 13 With the bridge plug, you can return your vehicle to the Stock without removing the cable loom. The bridge plug only fits into one position. Before using the bridge plug, please refer to Prepararion for installation on page 3.
Adjusting the Tuning Box Different climates and temperature can affect how the tuning box works on your vehicle. Depending on your location and type of octane fuel you can adjust the the tuning box by turning the dial up or down. To access the dial, remove the 4 torx screws located on the back of the tuning box and remove the cover to reveal the adjustment dial. This dial allows for small adjustments to the power setting which allows the box to work correctly in different climate conditions and on different quality fuel. The dial settings are 0-9 and work in reverse 0 being the highest setting and 9 being the lowest (A-F are not used in this application) 0-3 Dial setting recommended octane is 94-100 octane and dial setting 4-9 is recommended octane is 91-93 octane The dial on the NSX Tuning box comes preset on #4 and is designed to operate on 91 octane fuel or greater. To adjust the dial use a flat head screw driver to turn the dial up or down. 14
