DANGER! Check for proper clearance between engine components, such as the distributor, coil, etc., and the throttle body. Also check for clearance between the air cleaner and hood. If any interference is found, correct the condition before continuing. Failure to do so can result in damage to the engine components, throttle body, or hood. 6. Position the STEALTH TERMINATOR™ Throttle Body Assembly (Item 4) over the manifold flange studs with the throttle lever located on the driver’s side. 7.
Figure 9 Figure 10 7.0 FUEL SYSTEM Connect the fuel system per the manufacturer’s instructions. 8.0 ECU MOUNTING AND WIRING OVERVIEW The Terminator™ EFI ECU (Item 10) can be mounted inside the passenger compartment (preferable location) or in the engine compartment. If mounted in the engine compartment, follow these guidelines: The ECU should be located such that it isn’t being directly hit by water or road debris.
Figure 11 9.1 Harness Routing If the ECU is mounted in the interior, the harness will have to be routed through the firewall into the engine compartment. Use a 2” hole saw to create a hole in a desired location if no other point of access is available. A Grommet (Item 14) is supplied for a 2” hole to seal this area.
9.2 Sensor Connections & Loose Wires At this time, connect the Bulkhead, CTS, WBO2, CAN, and Fuel (for optional fuel pressure transducer P/N 554-102) connectors to their dedicated sensors/connectors in the diagram on page 8. The loose wires shown in Figure 12 should be connected as follows on all systems. These wires come out of the harness about 40” from the ECU connectors except for the “12V Switched” wire (approximately 7”).
Do NOT use this input if you are using an aftermarket Capacitive Discharge (CD) ignition system such as a MSD, Mallory, or others. The ECU will be damaged if you connect to a capacitive discharge type ignition coil. NOTE: When using this input, the EFI will NOT control the ignition timing of the engine. The timing will be based on the distributor initial, mechanical, and vacuum advance, just like it did with a carburetor.
OPTION 2 WIRING: OPTION 3: “GM Small Cap HEI” Computer Controlled Distributor (Requires Holley Ignition Adapter PN 558-304) – Small and Big Block Chevy engines can use a small cap GM HEI computer controlled distributor that was available on factory GM vehicles from the 1980’s through mid-1990’s. This distributor is also available through MSD under part number 8366. The distributor (shown below) provides an engine speed signal to the EFI, as well as allowing the EFI to control the ignition timing.
OPTION 3 WIRING W/ CAPACITIVE DISCHARGE BOX (Such as MSD 6AL) OPTION 4: “Ford TFI” Computer Controlled Distributor (Requires Holley Ignition Adapter PN 558-305) – Ford Sequentially Injected 5.0-5.8L engines from 1987-1995 used this distributor. This option will allow the EFI to control the ignition timing. OPTION 4 WIRING: www.holley.
OPTION 4 WIRING W/ CAPACITIVE DISCHARGE BOX (Such as MSD 6AL) 11.0 ADDITIONAL OUTPUTS There are 3 optional outputs available on the system that can be used for the following features: Air Conditioning Shutdown at wide open throttle Electric Fan #1 output Electric Fan #2 output Three outputs are located in the “Input/Output” connector. This is a 3 Pin connector is located about 52 inches from the ECU. A mating harness is included with the system.
12.0 TRANSMISSION WIRING The transmission harness can be used on 4L60E, 4L65E, 4L70E, 4L80E, and 4L85E transmissions. Each connector should be labeled. Transmission ECU Connector (P4) – Plugs into the ECU. Plugs into the last connector opposite the main harness. Main Transmission Connector – Simply plugs into the connector on the transmission. Located on the driver’s side of a 4L80E (installed horizontally) and the passenger side on a 4L60E (installed vertically).
13.0 PREVIOUS INSTALLATION REQUIRED At this point, the installation of your EFI system should be 100 percent complete. The ECU, TERMINATOR™ Handheld controller, throttle body and intake hardware, all sensors, wiring, fuel pump, regulator and return line, and all other hardware should be installed. The vehicle should be ready to start and run. If this is not the case, refer to the hardware installation manual included with your particular system. 14.
16.0 HANDHELD NAVIGATION & USE The 3.5” handheld utilizes a touch screen display. All navigation is done through “touching” an icon or button on the screen . The following is an overview of the different types of adjustment screens that are used in the display, and that may be utilized when tuning or making selections. 16.1 Making Adjustments Slider Bar: Slide the bar left or right with the stylus, or use the right and left arrow keys for fine adjustment (Figure 14).
Figure 17 Figure 18 Figure 19 Figure 20 7. If your engine is up to 409 cubic inches, select “Up To 409 CID”. If your engine is larger than 409 cubic inches, select “410 CID and Larger” (Figure 21). 8. The next choice should be dictated by the camshaft size and characteristics (Figure 22). If you have no idea, just simply select “Don’t Know”. The choices are further defined as: “Street Strip” – Camshafts with over 225 degrees duration at .050” valve lift (225º@.050”).
Figure 23 Figure 24 10. Select “GM Small HEI” or “Ford TFI” (Figure 24). Proceed to step 12. 11. If you are not controlling timing, you will have the following two choices. It is important the correct item is selected, as well as to double-check that you used the proper input wire when the vehicle was wired. “Coil – (neg)-” – Select this if you are NOT using an aftermarket Capacitive Discharge (CD) ignition box such as a MSD, Mallory, or others. This is for stock, factory inductive ignition coils.
Step 4: Select ‘Done’ Step 3 20.0 TRANSMISSION SETUP At this time, if an electronic transmission is being used, basis drivetrain parameters need to be set up. 20.1 Transmission Selecting TRANSMISSION brings up the following menu. There are two areas you can modify; TRANS SETUP and SPEED CALC. These are reviewed below. Transmission setup Figure 27 20.1.1 Trans Setup Transmission RPM: If this RPM is exceeded when in manual shift mode, the transmission will upshift automatically.
NOTE: The terminator harness does not have a Speedometer output wire, nor is the calibration programmed for it. Figure 29 Figure 31 Figure 30 Figure 32 21.0 SENSOR VERIFICATION Before starting the vehicle, verify that all of the sensors are reading properly. At this time, turn the key off, and cycle it back on. At this time you should hear the fuel pump come on and run for 5 seconds. Check for fuel leaks at this time as well. On the HOME SCREEN, select the MONITOR tab.
.0 SETTING IGNITION TIMING If you are using a computer controlled GM HEI or Ford TFI distributor, you must sync up the ignition timing with the ECU. You must have a timing light to perform this. You will possibly need a dial-back timing light or a harmonic balancer that is degreed up to 40 degrees. Again, open the Sensors monitor screen. You will see the “Ign Timing” parameter which will display what the commanded ignition timing is. Rev the engine up (CAREFULLY) to approximately 2000 RPM.
between 2 and 10 with the engine in neutral and up to operating temperature. Also make sure the “TPS” value is showing a value of 0. If it is not, you need to perform a TPS AUTOSET. If the “IAC Position” value is showing zero, you must close the throttle plates until it reads a value of 2-10. Slowly turn the throttle shaft adjustment screw on the throttle body out (counter-clockwise).
27.1.1 Multi-Gauge Sensors: Manifold Absolute Pressure (MAP), Coolant Temperature (CTS), Throttle Position (TPS), AFR Left, Engine RPM (analog), Battery Voltage, Ignition Timing, Manifold Air Temperature (MAT), Fuel Pressure, Engine RPM (digital), and Fuel Injector Duty Cycle. Air/Fuel Ratio: AFR Left, Target AFR, AFR Right, Closed Loop Compensation, Fuel Learn, Closed Loop Status, Engine RPM (analog), Learn Status, Fuel Injector Pulse Width, Engine RPM (digital), and Oil Pressure.
Figure 36 Figure 37 Samples of Monitor Screens 27.1.3 Diagnostics Channels displayed are: AFR Left, AFR Right, MAP, TPS, MAT, CTS Figure 38 – Sample Diagnostics Screen 28.0 Custom Setups 28.1 Dash Setup Up to three (3) Custom gauge layouts can be created on the 3.5 Touch Screen. Follow these steps to configure: Step 1: Choose ‘Dash Setup’ from the Multi-Gauge screen (Figure 39). Step 2: Choose the Dash number to be configured (Figure 40). Figure 39 www.holley.
28.2 Channels Scaling Each HEFI channel displayed by the 3.5 Touch Screen can be configured to have caution and warning indicators. To do this, choose ‘Channel Scaling’ from the MONITOR menu. Cautions will display as Yellow and Warnings will display as RED when using the MultiGauge screens. Figure 41 Figure 42 Figure 43 Figure 44 29.0 FILE SAVING/LOADING The following areas review the options located under the FILE selection.
29.1.1 ECU Overview Information specific to the engine and ECU configuration is shown here, these include the name of the current global folder, transmission type, ignition input type, WBO2 type, throttle body type, fuel system type, and ECU firmware version. Note that this menu is view only – no information can be changed. Any changes to engine or transmission setup must be done through the TUNING or WIZARDS menu. Figure 46 Figure 47 29.1.
.1.3 ECU Data Logging Holley HP and Dominator systems come standard with powerful data logging capabilities. Logging can be stopped and started via the 3.5 Handheld. The sampling rate is adjustable from 1 to 100 samples per second and can be changed by selecting ‘Setup’. Typically a high sampling rate is used for drag racing and a lower rate may be used for something such as road racing.
29.1.5A Touch Calibrate The touch screen may be recalibrated by following the on screen prompts. Figure 57 29.1.5B Local Info Displays device and firmware information for the 3.5 Handheld. Figure 58 29.1.5C Local Options By selecting ‘Restore screens on startup’ the 3.5 Handheld will revert to the last screen used prior to powering off. 30.0 BASIC TUNING The TERMINATOR™ systems allow the user to perform some basic tuning changes to help optimize mileage, drivability, and performance.
30.1 Basic Fuel Selecting BASIC FUEL brings up the following menu: Figure 60 30.1.1 Target AFR Allows changes to the Target Air/Fuel ratio at idle, cruise, and wide open throttle. The following are typical values and some tuning notes. Figure 61 Figure 62 Idle Air/Fuel Ratio – Typically between 13.5 and 15.0. Engines with larger cams may need a richer setting for smoothest idle. Cruise Air/Fuel Ratio – Typically between 13.5 and 15.5.
Figure 63 Figure 64 30.1.3 Fuel Prime Fuel prime is an option that is enabled by default in all of the base calibrations. The fuel prime function injects a small shot of fuel into the intake manifold when the ignition is turned on, wetting the intake and allowing the engine to start much quicker. The amount of fuel is based on the engine temperature and how long it was since the engine previously ran. This amount of fuel can be increased or decreased by changing the “Percent” value.
30.2.2 Learn Speed This parameter adjusts how fast the learning process occurs. In the beginning with a new tune it should be set to “Fast”. After the vehicle is driven under various operating conditions, and is running well, it is advised to disable learning, OR slow the Learn Speed to “Slow”. Figure 68 Figure 69 Figure 70 30.3 Basic Idle Selecting BASIC IDLE allows you to change the Target Hot Engine Idle Speed. This should be adjusted to your desired idle RPM. Values between 650-800 rpm are typical.
30.4 Spark Figure 73 Figure 74 All Holley base tunes contain timing curves that will provide adequate engine operation, however the ignition timing at idle, cruise, and wide open throttle can be adjusted independently from each other to compensate for different engine combinations and geograph ical and climate extremes. The following are typical values for each: Idle Timing – 18-34 degrees is typically used at idle. The larger the camshaft, the more timing is usually used.
Figure 75 Figure 76 Figure 77 Figure 78 Figure 79 30.5.2 WOT Shifts Use this menu to choose the RPM at which the transmission will upshift at WOT. Each gear change may be adjusted independent of the others. Figure 80 www.holley.
30.5.3 Torque Converter Clutch (TCC) Parameters Contains parameters that tune TCC activation and deactivation. Minimum RPM to Enable TCC - Minimum engine speed at which the TCC will apply. This value can be adjusted so that engines with large camshafts do not hesitate surge if the TCC is applied at too low of an engine speed. RPM to Disable TCC - Used to unlock the TCC once it is locked. The Lock and Unlock values should not be too close together, or they will continuously lock and unlock.
Figure 87 30.5.5 Line Pressure Tune the line pressure vs. TPS or MAP for each gear. A lower duty cycle (moving towards 0%) increases line pressure with 0% providing maximum line pressure applied. Values above 40-50% typically result in a line pressure too low for any throttle position, which may result in transmission damage. Figure 88 Figure 89 31.0 SYSTEM SETUP 31.1 System Tuning From the HOME MENU, select TUNING, and SYSTEM.
31.1.1 Outputs The OUTPUT screen allows for the Fan #1 and Fan #2 ON and OFF temperatures to be adjusted. The ON temp needs to always be a higher value than the OFF temp. Use a difference of at least 5 degrees so they aren’t cycling excessively. In Terminator Kits these are ground outputs that should be wired to trigger the fan relays.
Progressive TBI Enable/Disable: This should be selected if using a TBI throttle body with progressive throttle linkage. All 4 BBL TERMINATOR™ TBI systems do NOT have progressive linkage, so this should not be checked. This will NOT be shown if you have selected a MPFI application. TBI Secondary Blend: If using a TBI with progressive linkage, this value is used to start the ramp-in of the secondary fuel injectors as the rear throttle plates open. Enter the TPS when the rear throttle plates start to open.
32.0 ADVANCED TUNING From the HOME MENU, select TUNING, and ADVANCED. There are four areas you can modify; ADV FUEL, CLOSED LOOP, ADV. LEARN, AND ADV. IDLE. These are reviewed below. The Advanced Tuning areas typically won’t ever be needed to be changed. However, after getting used to the TERMINATOR™ EFI system, there may be some fine tuning of various parameters that you’d like to perform. Figure 100 32.
Figure 102 Closed Loop Enable/Disable: This menu enables or disables closed loop operation. There is typically no reason to turn off closed loop operation unless you suspect an oxygen sensor problem and want to disable the sensor. Note: Self-Tuning requires closed loop operation to function. Closed Loop Limit: The maximum percentage the ECU is allowed to deviate (+/-) from the base fuel calibration in order to maintain the commanded target air fuel ratio.
Figure 107 Figure 108 32.3 Advanced Idle The ADVANCED IDLE parameters adjust specific characteristics of how the idle air control motor functions on engine decel and startup. Selecting ADVANCED IDLE brings up the following menu: Figure 109 32.3.1 IAC Rampdown The Idle Air Control (IAC) motor is a stepper motor located in the throttle body that controls the idle speed of the engine by metering air. It also operates during engine cranking and when the engine returns back to idle.
Figure 110 32.3.2 IAC Speed This menu is used to select the type of IAC motor application that is being used. This selection drives the background param eters that control the IAC motor. These parameters have been fine tuned for each of these applications, eliminating the need for the us er to perform further modifications Figure 111 Figure 112 32.3.3 IAC Startup These parameters control the position of the IAC when the engine is cranking and immediately after it starts.
Figure 113 32.3.4 Idle Spark Idle spark is a feature active only when the ECU is controlling timing. When enabled, the ECU modifies commanded timing at idle to help maintain the target idle speed. Figure 114 Figure 115 NOTE: This feature should be disabled when checking base timing with a timing light! If not disabled rev the engine to approximately 2000 RPM when syncing timing. www.holley.
APPENDIX 2.0 SENSOR DIAGNOSTICS AND STATUSES Sensor diagnostics are included in the handheld. If one of the main sensors has some type of error, a small, blinking red circle will appear in the upper right of the screen. To navigate to the diagnostics, select MONITOR and DIAGNOSTICS. If there is an issue, an error will also be shown on any of the MONITOR or GAUGES screens. Wideband Oxygen Sensor Status – Shows status of wideband oxygen sensors. Text … Init..
