    A tuner has requested for me to log these values through the BT software... how do i find these values?

    I have a BT cable/software and I am looking to log these values:

    Lambda (Bank 1) – Internal wide-band oxygen sensor bank 1.
    Lambda (Bank 2) – Internal wide-band oxygen sensor bank 2.
    Ped Pos. (%) – Accelerator pedal position.
    TPS Act. (%) – Actual Throttle position.
    Timing Cyl. (1) – Ignition timing in degrees before top dead center.

    Load Act. – Actual calculated engine load value.

    Load Req. – Requested calculated Load from the ECU.
    Coolant Temp. – Engine coolant temperature.
    Engine Oil Temp. – Engine oil temperature.
    Charge Air Temp. – T-Map sensor value of charge air temperature.
    Boost Error – The Difference between Boost mean and requested.
    Req. Boost Abs. – Requested boost calculated by the DME in an absolute value.
    Boost Mean Abs. – A rolling mean average of boost.
    Boost Set point Factor – Boost pressure set point factor utilized by WGDC system.
    Boost – Manifold Absolute Pressure.

    RPM – Engine speed in revolutions per minute.
    Vehicle speed – Speed calculated by vehicle speed sensor.
    Wastegate Duty Base – Base percentage of wastegate solenoid duty cycle (0 to 100%).
    Wastegate Duty After PID – Percentage wastegate solenoid duty cycle after system PID control
    (0 to 100%).
    Wastegate Duty Bank 1-2 % - Percentage of actual wastegate solenoid duty cycle at bank 1 (0 to
    100%).
    STFT 1-2 – Short term fuel trims for bank one and two displayed in %. (See LTFT for description)
    LTFT Bank 1-2 – Long term fuel trims for bank one and two displayed in %.
    Does anyone have a recall file or know what these would be labeled as?

    Thank You

    What I've been able to guess:

    Lambda (Bank 1) – Internal wide-band oxygen sensor bank 1. Maybe: "Lambda Value In Front Of Catalytic Converter Bank 1"?


    Lambda (Bank 2) – Internal wide-band oxygen sensor bank 2.
    Maybe: "Lambda Value In Front Of Catalytic Converter Bank 2"?


    Ped Pos. (%) – Accelerator pedal position.
    Maybe: "Pedal Value Control", "Pedal Sensor Potentiometer 1", "Pedal Sensor Potentiometer 2", "Pedal Value Requested Load", "Accelerator Pedal Value" or "Pedal Sensor 1"


    TPS Act. (%) – Actual Throttle position.
    Maybe: "Throttle Value Sensor 1", "Throttle Valve Nominal Value", or "Throttle Value Actual Value"

    Timing Cyl. (1) – Ignition timing in degrees before top dead center.
    Maybe: "Ignition Point Cylinder 1" or "Ignition Angle Cylinder 1"


    Load Act. – Actual calculated engine load value.
    Maybe: "Load Value For Misfire Detection"?


    Load Req. – Requested calculated Load from the ECU.
    Maybe: "Calculated Load Value"


    Coolant Temp. – Engine coolant temperature.
    "Coolant Temperature"


    Engine Oil Temp. – Engine oil temperature.
    "Engine Oil Temperature"

    Charge Air Temp. – T-Map sensor value of charge air temperature.
    "Intake Air Temperature"

    Boost Error – The Difference between Boost mean and requested.
    ?


    Req. Boost Abs. – Requested boost calculated by the DME in an absolute value.
    ?


    Boost Mean Abs. – A rolling mean average of boost.
    ?


    Boost Set point Factor – Boost pressure set point factor utilized by WGDC system.
    ?


    Boost – Manifold Absolute Pressure.
    Maybe: "Pressure In Front Of Throttle Valve" or "Pressure After Throttle Valve"



    RPM – Engine speed in revolutions per minute.
    "Engine Speed"

    Vehicle speed – Speed calculated by vehicle speed sensor.
    "Speed" or "Speed 2"

    Wastegate Duty Base – Base percentage of wastegate solenoid duty cycle (0 to 100%).
    ?

    Wastegate Duty After PID – Percentage wastegate solenoid duty cycle after system PID control (0 to 100%).
    ?


    Wastegate Duty Bank 1-2 % - Percentage of actual wastegate solenoid duty cycle at bank 1 (0 to 100%).
    ?


    STFT 1-2 – Short term fuel trims for bank one and two displayed in %. (See LTFT for description)
    "Multiplicative Fuel Adaptation Low Load Bank 1"?
    "Multiplicative Fuel Adaptation Low Load Bank 2"?



    LTFT Bank 1-2 – Long term fuel trims for bank one and two displayed in %.
    "Multiplicative Fuel Adaptation High Load Bank 1"?


    "Multiplicative Fuel Adaptation High Load Bank 2"?

    That makes sense... Usually I would log through my Procede but Piggyback ECUs can't datalog in their Stock Map (Map 0 for me). So I flashed my Factory ECU but wanted to log it with no interference from my piggyback.

    Just incase anyone else needs it, I set up to log the following values:

    <SelectedValue>Intake air temperature</SelectedValue>

    <SelectedValue>Engine speed</SelectedValue>

    <SelectedValue>Throttle valve actual value</SelectedValue>

    <SelectedValue>Lambda-actual value group 1</SelectedValue>

    <SelectedValue>Lambda-actual value group 2</SelectedValue>

    <SelectedValue>Pressure in front of throttle valve</SelectedValue>

    <SelectedValue>Accelerator pedal value</SelectedValue>

    <SelectedValue>Ignition angle cylinder 1</SelectedValue>

    <SelectedValue>Lambda value in front of catalytic converter bank 1</SelectedValue>

    <SelectedValue>Lambda value in front of catalytic converter bank 2</SelectedValue>

    <SelectedValue>Target boost pressure</SelectedValue>


    This should get me enough info for the time being... Then I can start logging with the Procede Maps active as I used to do to pull the rest of the needed information. I'm sure the BT software has all the values, there are literally hundreds to choose from - but none of them are labeled in layman's terms.
