    Not really possible directly.  You may be able to do it via a GP PWM with a motor controller that has is own internal PID.

    amg reacted to Simon in Signal Switch for Solenoid Control?   
    The switch could be wired to a Di and then that will activate a AUX out to switch the solenoid. 
    Should work well.

    Starter Control
     
    Starter Control provides ECU managed operation of the Starter Motor.
     
    There are two requirements for starter control to function:
     
    · A Digital Input Function must be setup as Start Position. This could be a conventional key activated ignition switch or a push button. and
    · An Auxiliary Output Function must be setup as Starter Solenoid. This output should be connected to starter solenoid relay.  
     
    Starter Control Settings
     
    Start Switch Mode
     
    Selects the mode of starter control. Options available are:
    · OFF - No starter motor control by the ECU. · Test - Use for testing input/output functionality only. When Start Status is active the ECU will activate the Starter Solenoid Auxiliary Output. No other conditions are checked, this could potentially lead to starter damage, engine damage or personal injury if operated at the incorrect time. · Normal - Behaves the same way a typical vehicle starting system.  The key is turned and the engine will crank until the key is released.  However it offers the added protection of preventing the starter being engaged at a high engine speed and the option to disable starting if the vehicle is not in Park/Neutral or is immobilised. When the conditions specified for Deactivation RPM, Anti-theft Lockout and Neutral/Park  Lockout are met AND Start Status is active the ECU will activate the Starter Solenoid Auxiliary Output. The auxiliary output will stay active until the Start Status turns off OR the the Deactivation RPM is reached. · Start/Stop - Allows the use of a single button for both starting and stopping the engine.  When the engine is stalled, pressing the button will crank the motor over.  Once the motor is running, pressing the button again will stall the engine.  This mode is suitable for a single start/stop button on the handle bar of a motorbike or jet ski. When the conditions specified for Deactivation RPM, Anti-theft Lockout and Neutral/Park  Lockout are met AND Start Status is active the ECU will activate the Starter Solenoid Auxiliary Output. The auxiliary output will stay active until the Start Status turns off OR the Deactivation RPM is reached. Once the engine is running, if the engine speed is above the Deactivation RPM AND the Start Status becomes active the ECU will apply a 100% Fuel and Ignition cut to the engine. · Touch Start - Allows a starter motor button (or key) that can be momentarily pressed to start the engine.  The driver taps the button and the ECU will take care of starting the engine.  Typical applications for Touch Start mode would be remote starting or a jet boat. When the conditions specified for Deactivation RPM, Anti-theft Lockout and Neutral/Park Lockout are met AND Start Status is momentarily active the ECU will activate the Starter Solenoid Auxiliary Output until the Max Crank Time is met or the Deactivation RPM is reached.  As of firmware version 5.5.6, pressing the start button again while the engine is running will stop the engine.  
    Starter Deactivation RPM
    Specifies the engine speed (RPM) above which the Starter Solenoid Auxiliary Output turns OFF.
    Use Anti-theft Lockout
    An option to make the Starter Solenoid Auxiliary Output conditional upon Anti-theft status. If set to Yes and Anti Theft Status is Active the Starter Solenoid Auxiliary Output will not function.
    Use Neutral/Park Lockout
    An option to make the Starter Solenoid Auxiliary Output conditional upon Neutral/Park status. If set to Yes and Neutral/Park Status is OFF the Starter Solenoid Auxiliary Output will not function.
    Max Crank Time
     
    Used only on Touch Start Start Switch Mode, this is the maximum amount of time the starter will be allowed to crank if the engine does not start.
     
     
    Starter control Examples
     
     
    Example 1:  Normal Mode with Anti-theft
     
    Assume Starter Control is set up as:
     
    Start Switch Mode = Normal
    Starter Deactivation RPM = 600 RPM
    Use Anti-theft Lockout = Yes
    Use Neutral/Park Lockout = No
     
    With the above settings the ECUs Starter Control would activate the starter motor if:
    · Engine speed is less than 600, and · The anti-theft signal is off and · The driver presses the start button (or turns the key).  
     
    Example 2:  Start / Stop Mode with Neutral / Park Lockout
     
    Assume Starter Control is set up as:
     
    Start Switch Mode = Start / Stop
    Starter Deactivation RPM = 550 RPM
    Use Anti-theft Lockout = No
    Use Neutral/Park Lockout = Yes
     
    With the above settings the ECUs Starter Control would activate the starter motor if:
     
    · Engine speed is less than 550, and · The Park/Neutral signal is active and · The driver presses the start/stop button.  
    With the above settings the ECU would apply a 100% cut to both fuel and ignition if:
     
    · Engine speed is greater than 550, and · The driver presses the start/stop button.  
    Note: The fuel and ignition cut will remain until engine speed is zero RPM.

    amg reacted to Simon in Aux 9/10 & 17/18 under voltage   
    For the manual cal you need to move the throttle plate by hand to fully open and fully closed to get the matching voltages.
    ·Manual Calibration - Type the sensor open and closed voltages into the TPS (Main) Closed, TPS (Main) Open, TPS (Sub) Closed and TPS (Sub) Open settings.  The TP(sub) 100 setting must be set to the TP (Main) percent that TP (Sub) stops changing if a non linear sensor is used.  If the TP (Sub) signal changes over the entire range of throttle plate movement (most common) then set TP(sub) 100 to 100%.  Note: the sensor pin voltages can be seen in the Analog Inputs tab of the Runtime Values Window (press F12).

    This would think is a fail safe of the unit so that if the wire was disconnected it would run full speed.
    Our drive is geared to pull the signal low and the Duty cycle refers to the % time it is held low.

    amg reacted to Brad Burnett in Camshaft Trigger Edge / Sync Mode   
    That would be "cam pluse 1x"
    If it were one tooth that spanned about 1/2 the way around, that would be cam level.
    As for rising or falling, I would start with rising.
    Once you get to cranking the engine, I would do a scope trace and if the rising edge of the cam signal happens at the same time as crank edge then switch to falling.
    With hall sensors it really doesn't matter unless one side is dirty/has some weird shape or happens at the same time as the trigger edge on the crank.
    And with the 60-2, the cam pulse cannot occur within the missing tooth or 30deg after it.

    I know that this doesn't answer your question, but the greater water flow through a closed loop water 2 air circuit the quicker air ambient air cools the water down. 
     
    Use a 2D PWM table with rpm on the axis. 500rpm @ 75%DC. Set condition 1 only with rpm greater than 500rpm

    amg reacted to Brad Burnett in Thunder Lambda Inputs   
    You can wire two lsu4.9 sensors direct to the ecu and let the ecu do the control of the sensors.
    You could utilize the zeitronix controllers that you have, but the lambda reading will typically be slightly off due to the analog to digital conversion. 
    My choice would be let the ecu do the controlling.
