    engine management

    is there anyone out there who has installed a haltec engine management system on a BPT engine. I need some help. To be specific it is a haltec E6X.

    #2
    This is for an E6K, but the X is basicly an updated version of the K.




    Installing a Haltech E6K on your Mazda BP Motor

    Preparing your motor prior to the install will take a little bit of time, but will be well worth it. Follow most of my instructions and you should be up and running in no time.

    Factory Harness Removal (Optional)

    Unplug the ECU and remove it from the vehicle. Clip all tie downs and unbolt all bolts holding any of the loom to the chassis. Pull the loom out from the engine bay through the firewall. This does not need to be done if you wish to keep cruise control or factory idle.

    Note: Some wire colors may vary, I have tried to spot them all and note them but it may differ on your harness,

    Haltech E6K Install Notes

    Fuel Injectors

    Batch Fire (Optional)
    Batch fire is only for people who need to use the extra Digital Outputs on the E6K. This mode fires the two banks of injectors alternately, i.e. 1+2 fire, 3+4 fire. This in term is like waste-spark but with fuel. You will always be injecting 1 cylinder with un-needed fuel.

    INJ-1 (LIGHT BLUE | +13.8V) Cylinder-1 (Yellow | WHITE / RED)
    INJ-2 (BLUE / RED | +13.8V) Cylinder-3 (Yellow | WHITE / RED)
    INJ-3 (GREEN / RED | +13.8V) Cylinder-4 (Y/B | WHITE / RED)
    INJ-4 (PINK | +13.8V) Cylinder-2 (Y/B | WHITE / RED)

    Sequential (Recommended)
    Sequential injection allows fuel to be delivered to the engine at a time that produces best combustion. Since this time is different for each cylinder, sequential systems inject fuel at different engine angles for each cylinder. This means better gas mileage and smooth idle!

    Ignition / Distributor

    Factory Ignition
    When using the factory ignition setup the Ignition Setup to the following settings:

    Trigger Input: Rising Edge
    Trigger Output: Falling Edge
    Fires on: Falling Edge
    Constant Charge
    Charge time is 3.0ms.

    This is for using the stock ECU harness and leaving the ignition circuit intact.

    Using an MSD 6A
    Change the charge time to 1.0ms and the Firing Edge to Rising.

    External Sensors

    Throttle Position Sensor
    The factory GTX TPS can be used in place of the haltech sensor if you do not want to fabricate the appropriate mount, or do not have a “D” shaft type throttle body. The automatic transmission TPS from the Escort GT or Protégé LX will be the same.
    Note: Each TPS sensor requires a different throttle body.

    Idle Switch (RED / WHITE) Ground (BLACK)

    Oxygen Sensor
    If you are using the Haltech 4-wire o2 sensor or a standard 4-wire Bosch o2 sensor the following wiring diagram will suit you. To retain the use of the factory 4-wire o2 found on most GTX and N/A motors use the second diagram, you will need to retain your factory harness for this to work properly.

    Cooling Fan Relay
    Be careful when hooking this up, always use a Ground to test this wire with the key on. If the fan comes on then it is ok to hookup the PWM to it. The settings for most cars are:

    On Temp: 190
    Off Temp: 180

    *Using a 180F Thermostat.

    Boost Control Solenoid
    There are three parts to the solenoid, one is the wastegate inlet, one is the manifold pressure inlet and one is the breather. You may have to switch the wastegate and manifold lines according to which way you hook up the BCS wires. PWM Settings are:

    Period: 33mhz.
    Use Wastegate: MAP 1
    Boost Cut: 12

    BAC Valve
    The BAC valve works in conjunction with the ISC (Idle Speed Control) valve on this motor. From 0-104F the wax inside the ISC starts to melt allowing more air into the manifold. There are two settings to this and they vary for every car, they are below:

    Input/Output
    Idle Speed Control: DISABLED
    Target Idle Speed: 1000
    Cold-Idle Up: 200
    Start RPM: 200
    Number of Steps: 100
    Cold Temp Limit: 104F
    Cold Min Pos: 78 *varies
    Hot Min Pos: 77 *varies
    Cold Open: 10
    Hot Open: 20

    PWM 3
    Period: 10ms.
