    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.
