    the engine, a vacuum will form in the ventury sucking harder on the idle jets and main jets and so make the cranking mixture rich enough for starting. The moment the engine starts, a vacuum canister will force the choke butterfly open slightly causing air to flow freely through the ventury. As the engine heats up the choke butterfly will open completely also releasing the bottom throttle to its normal position.

  • Page 11: Jumper Selection

    4.3 Jumper Selection The TITAN ECU has standard harnesses for all engine configurations. The two basic groups of sensors require 12V for Hall and Optic sensors and 5V for Magnetic sensors. This selection between the supply voltages is done by jumper settings. There is also a stronger pull-up resistor required for the hall or Optic sensors and they are also selected with the Jumpers.
  • Page 12 • Ensure that the enclosure of the ECU is grounded with at least two metal screws onto the metal body of the car. If the ECU is not bolted directly onto an earthed metal surface, you MUST make sure that you run a 4mm ground wire to one of the ECU’s bolt holes, otherwise your ECU will not power up and you will damage the MAP sensor permanently.

    6.7.1.2 Engine Configuration Cylinders – 2,3,4,5,6,8 or 12 cylinders can be typed in this block, depending on the engine specific ECU. Most ECU firmware will over-write this block at start-up. Map sensor – adjusts the map sensor range that you use e.g. 1bar = 10, 2.5bar=25. If you have a 2.5 bar sensor but you only use 0.5 bar boost, enter a value of 15 for 1.5 bar and calibrate the MAP sensor so that you are able to make full use of the complete vacuum range for correction adjustment.
  • Page 41 Example: RPM for a shift light, RPM or TPS to switch nitrous on, water temp to control a fan relay. Also set the appropriate values in the min and max blocks e.g. shift light – min 5000 max 8000. The light will switch on at 5100 RPM’s and switch off at 8100 RPM’s. If the min value is smaller than the max value, the relay will switch on between the limits.
  • Page 42: Timing Configuration

    6.7.2.1 Timing Configuration Maximum Timing – this is the max timing allowed by all the timing maps combined. Coil time – 2ms to 5ms. This is the maximum charge time that the user can select. The ECU will vary the charge time automatically according to vacuum load from 2ms to the user selected value. If the ECU heats up it is a result of too large charge times.
  • Page 43 6.7.3 Fuel Setup (Alt 3) 6.7.3.1 Fuel Configuration Start enrichment – Set a value in milliseconds here for start enrichment. This enrichment is added to the calculated fuel when the engine is started. It will then be phased out in a certain RPM’s.

    the throttle position in conjunction with RPM is used to calculate engine vacuum. It is a bit more difficult to tune but can be done. A disadvantage is that it cannot compensate for sea level correction. The TPS is calibrated as normal to allow the tuner to make use of the full graph. Then the TPS signal is projected in the Map sensor’s graphs.
  • Page 45: Active Sensors

    The RPM correction maps are divided in four groups of map values. A low, cruise, high cruise and high map. The Low map – this is the map for low throttle cruising or idle The Cruise map – this is the map for normal cruising The High Cruise map –...
  • Page 46 Then click on the Write to ECU button. When you switch the ECU off and on again, the TPS bar should indicate 0% when pedal is released and 100% when pedal is pressed. Remember that idle control will only take place when the TPS is less than the value set in the Fuel cutoff TPS block.
  • Page 47 6.7.4.3 Idle Control Before adjusting the idle control you must select which type of valve is on the engine. Remember if it is a stepper control (4 to 6 wire), then you require the external electronic driver. Also remember to set the relevant GP outputs to Idle Control. Idle control can be used for two-wire and non spring loaded three-wire valves.
  • Page 48 6.7.4.4 Lambda Configuration This block is used to set control parameters for the ECU to use the lambda signal to adjust fuel enrichment while driving. Note that lambda sensor correction will only operate when the engine temperature is above 60°C. The target volts are the set point for the ECU to achieve during fuel correction.
  • Page 49 6.7.5.1 Launch Control The launce control is activated by a push button on the dashboard to activate and a button on the clutch pedal if automatic latch up operation is required. Once the RPM’s go over 4000 then these 3 parameters will take effect. The new rev limiter will cut the fuel and spark. The timing will be retarded and the fuel mixture will be enriched.
  • Page 50 If you are not sure on the injector sizes, first tune the engine with only the primary injectors. Choose a certain RPM and load on manifold pressure and set the Vacuum Limit field higher so that the secondary injectors stay off. Now start with 50% value in the Compensation % field. Reduce the Vacuum Limit so that the secondary injectors start operating.

You may switch the real-time tracking on so that the green adjustment bar will follow the blue active bar. Then you will adjust the value where the RPM’s is at the time. Notice the graph below 400 RPM’s is set to the cranking timing.
  • Page 55 6.8.2.1 Main Jet Setting The base line fuel is calculated by the ECU and not mapped in a look-up table like matrix systems. Calculations alone cannot compensate for all deviations in and engine. The ECU uses correction graphs to compensate for all kinds of deviations. The Main Jet adjusts global fuel supply to the injectors much like the main jet in a carburetor would.
  • Page 56 6.8.2.2 Idle Jet Setting The Idle jet setting adjusts global idling fuel supply to the injectors much like the idle jet in a carburetor would. Calculations at idle uses a part of the main jet setting, and gradually fade away as the vacuum signal decreases under load.
  • Page 57 When the Pink vacuum bar moves between these zones, a different graph is selected on the Fuel RPM Map below. You can click on the mouse button and adjust with a mouse by simply dragging the graph. You may switch the real-time tracking on so that the green adjustment bar will follow the blue active bar.
  • Page 58 These two graphs will manipulate the target voltage with a certain percentage. As we use a narrow band sensor it is not recommended using this feature. It is ideal for a wideband sensor with a linear voltage output. Then you can activate the sensor to control over all load conditions. 6.8.4 Correction Maps (Alt 4) 6.8.4.1 Temperature Correction map This map is to set the water temperature correction mostly for cold starting.

    1,4,6,7,8 &9 are broken out of the communications connector if you are not using a Spitronics USB Converter cable. 5. Now switch the Ignition off and connect the Laptop to the unit. Switch it on again. Start the PC software and connect to the ECU. The engine data like the water temp sensor should be displayed.
  • Page 64 11. You may now crank the engine without the 10 way connector. Check that the Green LED flashes. Also look at the RPM signal on the timing map. It should show 200 to 300 rpm constant. If it shows erratic and run wild, do not try to start. First find the fault. It must be constant.
  • Page 65 9.1 Fuel Settings for Starting the Engine The ECU has n few sequences how to start the engine. An engine requires an initial prime pulse of fuel to start the moment the engine is cranked, then a richer mixture during cranking. Once it started, it also requires a certain amount of richer mixture than idling to get it going till normal idle settings can take over.
  • Page 66 To start the engine the first time, use the main jet slider. Start with a low value and increase it until the engine start. If it starts adjust the main jet so that it can idle. Always go for the leanest position (bottom) on the slider not to over fuel the engine.
  • Page 67 decreased. Increase the idle jet 4 to 6 pulses higher when the engine is lean. The lambda should now read on the rich side. Too rich will also cause the engine to lose RPM’s or the vacuum bar to move to the right. Increase the mixture to see where is the furthest point to the right on the lambda bar to determine the sensor maximum.
  • Page 68 9.4.3 Setting the Idle in Drive for an Automatic Gearbox Put the gearbox in drive. The vacuum bar should move a bit to the right. This is due to load on the engine by the torque converter. Now adjust the vacuum map graph around the vacuum bar till it idles at the right mix again.
  • Page 69: Battery Voltage Compensation

    The TPS % must be below this value. Set a value small enough to activate when the throttle is released. If no TPS are installed, uncheck the TPS under active sensors. Then this feature will only work with the next 2 functions. The vacuum signal must be lower than this value to activate the feature.
  • Page 70: Fault Finding

    subtract cranking fuel for startup. The main problem is wiring. If positive wires supply different circuits, the voltage will vary with current flowing through the common wires. As the injectors and ECU are supplied by separate circuits it is very important to follow the wiring instruction during installation.
  • Page 71 b. It may be that ignition timing is setup incorrectly. Then firing occurs at the wrong time and failing to ignite the fuel mix. Check again the timing setup for the specific engine. c. The plugs may be old or dead. Replace. 5.
  • Page 72 2. Too lean mixture. Try increasing the main jet value. 3. Incorrect rotor fazing or timing. Check with a timing light. 4. Incorrect magnetic trigger polarity. 5. Check the micro fueling and boost limiter blocks and see if the settings there are correct. A symptom will be that the milliseconds bar on the real time block will jump to 0.
  • Page 73: Specifications

    10.1.14 Engine lack power, idle erratic, or runs lean 1. The fuel pressure is erratic. This may be due to the pump sucking air on the in feed which causes cavitations and loss of pressure. This happens more frequent when the engine is hot.
  • Page 74 The ECU can sense any crank or cam sensors. Popular types are 60-2, 36-1, 36-2, Nissan Optic, Toyota 24+TDC, Rotary, Spitronics Optic and lot more. These are program specific, and are combined with the type of ECU firmware loaded by the Agent. Some sensors may not be incorporated in programs before but can be done on request.
