Thread: Wiring Switch For Datalog

  1. Default Wiring Switch For Datalog

    I can't seem to find the link or writeup on how to wire in a switch for datalogging. I know I've seen it before.

    You're welcome. I like having that easy datalog switch too.
    May God's grace bless you in the Lord Jesus Christ.

    A late question: Is the push button switch a momentary, or push on/push off?

    Read the two sentences in red & blue:

    Immediate vs Triggered Start Methods
    With “Immediate” & “Triggered” start methods and an option to use the ECU Log Trig Input, there are actually four combinations.
    We will address these separately:

    * Immediate Start Method with no ECU Log Trig – This combination results in logging as soon as the ECU is powered up and it
    continues going until the ECU powers down or you hit the “Max Log Time.” If you hit the max time, then the ECU wraps up the file and
    immediately starts a new one. If you want to log all of the time (including uneventful key-on time if the engine is not running) this one is
    for you. It would be advisable to set the “Logging Rate” rate very low or you will fill up the storage space in short order, and set the “Max
    Log Time” very high to avoid lots of little files.

    * Immediate Start Method with ECU Log Trig – This combination results in starting the log based exclusively on the ECU Log Trig
    input. That is pretty simple. The length of the log will be a function of the kind of switch you use and what you enter for “Max Log Time.”
    If you're using a momentary switch, it is pretty simple. The momentary ECU Log Trig Input starts the log, and the length of the log is
    set by the “Max Log Time.”
    It essentially ignores the switch input until it finishes the log. If you're using a toggle switch, the log will go at
    least for the time specified in the “Max Log Time”, but will continue beyond this time if the switch is still active.
    Beyond this time as soon
    as the switch is turned off the log stops. So really for this combination, the “Max Log Time” is actually specifies the minimum log time.

    * Triggered Start Method with no ECU Log Trig – This combination is useful if you know you always want to record data at a certain
    condition without having to worry about a switch. You can specify what condition will trigger the start of the log (like TPS>50,
    RPM>3000, or MAP>110 for instance) and then the log simply goes for the time you specify in the “Max Log Time.” Meeting the trigger
    conditions again during the log will not prolong the log, but of course meeting the trigger conditions again after a log is finished will start
    a new log. Many people choose to setup the trigger conditions based on things you would see at the burnout for instance and then set
    the log time long enough to capture the run.

    * Triggered Start Method with ECU Log Trig – This combination is the strictest in that you have to have the ECU Log Trig input active
    in combination with meeting the trigger condition based on the variable and threshold you selected. BOTH must be active at the same
    time for the logging to start. While you can do this with a momentary switch input, you have to be confident that the trigger condition will
    be met at the time you hit the switch. It might make more sense to use a toggle switch for the ECU Log Trig input when using this
    combination. After being triggered the log will run for at least the length of time set in the log time, and will continue to run so long as the
    ECU Log Trig input is active. What you do not have to do is select “ECU Log Trig” as the trigger input. That is already taken care of as a
    predefined system input and can actually cause confusion and problems if you use it as a trigger condition as well.

    Creating a Switched Input for the Internal Logger – A switched input can be created for the internal logger (+12V or Ground). Its
    function is described in the start methods above. It's created by selecting the System Parameters ICF & Basic I/O – Datalog. Select
    the "Enable Input for Internal ECU Log" to create this input.
    May God's grace bless you in the Lord Jesus Christ.

    Danny, sorry, missed the "momentary" part! I need to go back to reading comprehension 101.

    No problem, you're welcome. I only a momentary datalogger switch.
    May God's grace bless you in the Lord Jesus Christ.
