PLATE INSTALLATION The following steps describe the proceedure for the installation of the ECI plate and supporting hardware. Specific layouts may vary on your application. 3. Be sure that the mounting flange on top of the manifold is clean and dry. Install the provided extended carburetor studs and new base gasket onto the manifold. Be careful that no debris falls into the manifold as SEVERE engine damage may result. 1.
PLATE INSTALLATION 5. Install the assembled injector plate and new carburetor base gaskets onto the intake manifold. 8. If you desire to connect a coolant temperature sensor to the system, find a suitable location in the cooling system to install the coolant temperature sensor. Usually this will be in the intake manifold near the thermostat housing. NOTE: A coolant temperature sensor is not provided. An AUTOMETER® temperature sensor PN 2258 will need to be purchased separately. 6.

02 SENSOR INSTALLATION 1. The following steps describe the proceedure for the installation of the 02 sensor, bung and pigtail routing. Specific layouts may vary on your application. 1. Turn off the ignition and disconnect the negative battery cable. Jack up the car and place on suitable stands to enable access to the exhaust system. 4. Weld the provided O2 sensor fitting into the exhaust pipe. NOTE: The exhaust pipe was removed for illustration.
02 SENSOR INSTALLATION Orientation of 02 sensors should be set at either 10 or 2 O’clock 10:00 12:00 6:00 8 2:00
WIRING INSTALLATION 1. The following steps describe the proceedure for the installation of the Wiring harness and associated connections. Specific layouts may vary on your application. 5. Route the wiring pigtails for the injector(s) and other optional connections so they will not interfere with mechanical assembly or exhaust and then connect them to the injector(s) and optional locations. NOTE: See diagram on page 11, all of the wiring pigtails and connectors are labeled. 2.
WIRING INSTALLATION WIRING DESCRIPTION BLACK GROUND: Wire connects to a good ground, engine block or battery negative (-) teminal. RED POSITIVE 12V: Wire connects to a positive (+) 12 volt source, live in key on position. 2 PIN GREEN / ORANGE INJECTOR #1: Connector plugs into #1 injector. 2 PIN BLUE / ORANGE INJECTOR #2: Connector plugs into optional #2 injector for use with the 2 injector plate. WHITE TACH IN: Wire connects to tachometer lead or with MSD® tach adapter #8910 as per instructions .

PROGRAMING TO START PROGRAMING... 1. Insert the K&N® thumb drive to a USB port on your computer and install the provided software by following the instructions in the setup file (setup.exe). 2. After installing the software, connect the ECI to your computer using the provided USB cable. a.The ECI does not need 12-volt power to access and change settings. It will receive power from the USB for communicating. It is recommended to program the ECI before powering it up with a 12-volt source. 3.
PROGRAMING Injector 1 and 2 Settings Idle Air Fuel Ratio – Setting to add fuel at idle when in the idle RPM range. The Min RPM and Idle RPM limit must be set for this function to work. Example: If Idle Air Fuel Ratio is set to 14.7, minimum RPM set to 500 and Idle RPM limit is set to 1500, the ECI will add fuel above (lean) the Idle Air Fuel ratio of 14.7 and in the range of the minimum RPM and Idle RPM limit (500-1500 RPM). Air Fuel Ratio – Setting to add fuel when above the idle RPM limit.
PROGRAMING CONTINUED... Warm Duty cycle – Amount of fuel to add when warm engine temperature transition occurs. Cold Duty cycle – Amount of fuel to add when engine temperature is cold. Warm/Cold Transition – Temperature value to determine if engine is warm or cold. Other Cylinders – Drop down menu to select number of cylinders. Fuel Type – Drop down menu to select type of fuel being used. A custom fuel type setting is available. Stoichiometric Ratio – Ideal air fuel ratio for selected fuel.
