The What's Up Display is a Windows program used for Observation, Playback, Data Logging, and Analysis.

The main screen graphically displays various engine parameters. Other screens display trip information, VE table learn, and spark knock data. There is another screen (Analysis) that can display or create a text file of a data log. 

Most of the What's Up Display functionality is intuitive. A short time playing with the various menus and it will become apparent what they are used for. During live use or playback you can switch between the five main screens: WUD, MPG, VE, SPK, and DIAG at any time. Can use either the ALT key or the numbers 1 through 5 to change displays. There is also a small pop up for displaying malfunction codes.

Sensor Diagnostics:

The Diag display shows the raw sensor values. These values may be different then the value for the same sensor in other displays. The reason for this is that the ECM may be using a defaulted value for a bad sensor. An installation that is not using an IAT sensor will show this. The default value is shown on the main display, while the diagnostic display will show -40 °C/°F.

Data Logging Features:

During data logging the file can have markers placed into it. These markers will show up as green or yellow highlighted lines in the Analysis screen.  A tap of the space bar will be green, with a tap of the Tab key shown in yellow. These markers are also placed in the Dump File (from the Analysis screen). This makes them searchable by using the key words 'timestamp' and 'mark.' They both place a date time string in the log, along with the Tab marker placing an incrementing value.

VE Learn:

The Learn VE (from the File menu) screen does need some explanation. In order to learn a new VE table the current BIN file needs to be accessed. As learning takes place corrections will be applied to the VE tables from that BIN. With the learned changes a new BIN will be created or an existing BIN will be updated. The one important item to remember is that the 'read from' BIN for learning must be the same BIN the vehicle is being driven with. Whether live or from a data log, this is important.

VE Smoothing:

A smoothing can be applied to the VE tables. The Smoothing Factor found in the preferences menu defines the amount of smoothing. A smaller value is less smoothing, while a higher value is more smoothing. A value of 0 disables smoothing. When doing back to back VE Learns try a smoothing factor of 5 to 8.

AutoUpdate:

This is ONLY to be used with a product that automatically updates the EBL ECM BIN. Such as the EmUtility and an Ostrich (a real time emulator). It works by updating the learn to BIN after the defined time frame, clearing the correction data, and re-loading the VE information. It allows for the active BIN in the ECM to be learned and updated as the vehicle is being driven.

How to set up and use the VE Learn:

The VE Learn process can be accomplished with either BLM or WB data. If a WB O2 setup is available it is recommended over using the BLM learn. VE Learn can be accomplished as the vehicle is being driven, or afterward from a data log. A proper VE learn has several requirements. Most important is that the BIN used while the vehicle is driven needs to be available. Second is data from the EBL system. This can be live or from a data log.

If you have a WB O2 setup I recommend that it be used. Learning is faster with the use of a WB. If the end goal is closed loop operation, follow the WB learn with closed loop BLM learn sessions.

When using WB learn the closed loop operation needs to be disabled and the BLM values need to be held at 128. To do this set the closed loop enable temperature at a high value and set the key-on (init) BLM min/max values to 128.

If the vehicle has an exhaust gas recirculation (EGR) system, remove the vacuum line from the TB and plug the vacuum port. Disable EGR in the BIN by setting the enable CTS at the maximum (150 C).

If the vehicle has a charcoal cannister purge (CCP) system, remove the vacuum line from the TB and plug the vacuum port.

This is required during learn using either BLM or WB input.

Once VE Learning has been completed re-enable the EGR system. Now update the 'EGR - BPC vs VAC' table for minimal change in the BLM while the EGR system is active.

Once that has been completed the CCP system may be re-connected and placed into use.


Here is an outline of the steps required to setup for a learn.

1). Select:  File -> Preferences menu.

    a) select Learn From: BLM or WB.
    b) if WB is used set the "Preferred: WB" on the ADC Channels tab.
    c) set the Learn Minimum and Maximum CTS values within the engine normal operating range.
    d) set the Smoothing Factor value.
    e) click OK

2). Select:  File -> Learn VE menu.

    a) enter/select the BIN file that is to be learned from.
    b) enter/select the BIN file to create/write the new VE table to. This defaults to the current BIN with the PromId added to the filename portion. A different name can be edited or entered in.

    A note on the Learn-To BIN file name creation:

The WUD reads the PromId from the originating BIN, increments it by one, and uses that value as part of the learn to BIN filename. This same value is used as the PromId within the learn to BIN.  The next time this BIN is used as the originating learn from BIN, the PromId portion of the filename will be updated. So a series of learns will end up with successive filenames such as : mybin.bin, mybin_00001.bin, mybin_00002.bin, mybin_00003.bin, and so on.

    (learn is now enabled)

    Notes on the Learn-To BIN file creation:

3). In order to learn a new VE table it is time to either drive around or to play back a data log. Corrections will be made to the read-from BIN and applied to the write-to BIN. Use this BIN as the next one. The checksum is calculated and set in the BIN, ready to burn.

When observing the Volumetric Efficiency Learn screen a colored box will show the current RPM and MAP point. When this box is green learn is actively taking place. A yellow box shows when learn is not taking place. 


Analysis:

When selecting the analysis screen any current playback, data logging, or learn will be stopped. You may then select a data log to show on the screen, or a data log to dump to a text file. The created file can be read into Excel and various sections and/or parameters graphed. If the Dump Log is to be read into Excel, check the 'Single Header' box. Otherwise a new header row is inserted once a second.


1/4 Mile Performance:

From the Analysis screen the various performance information can be calculated and graphed. To select the start point left click the mouse on the desired line. Then click the 1/4 Mile button (or double click on the selected line). Once the graph is displayed a new start line may be selected. The graph will be updated to that new point. If a preference such as which WB is in use is changed, the Analysis data will automatically be recalculated and the graph redisplayed.

The accuracy of the performance data is affected by tire spin. Please keep this in mind. The calculated data is only as good as the input.


Creating User Devices for Data Logging:

In addition to the standard WUD WB units and fuel pressure transducers you can also data log any device that outputs a 0 to 5 volt linear signal. This may be anything from a TT-1 WB unit, EGT sensor(s), to accelerometers, to whatever you wish to log. Up to 16 different devices may be created. With the actual device physically connected to an ADC input on the EBL board, the user created device is then assigned in the Preferences ADC Channels dialog.

Note: connecting a device that outputs a signal greater then 5 volts or less then 0 volts can damage the EBL. So be sure of what you are connecting to an ADC input.

The device voltage will be converted to the units as set in the User Devices and output to the .EBL Dump Log output file.

All that is required to create a device is a name to identify the device, the unit name (KPa, AFR, G's, °C, °F, ...), and the voltage/unit range. For example, lets say you have a TT-1 WB unit that you are going to data log. At 0 volts the AFR is 10:1, and at 5 volts the AFR is 20:1. It is as simple as using 'TT-1 WB' for the name, 'AFR' for units, then 0 volts for 10 and 5 volts for 20.

For the number of places to the right of the decimal point, 1 is entered. This will show to tenths of an AFR.

Here is a screen shot of this entry  (ALT-File, U):

UserDevices0

Now click the Apply button and the device is created.

The 'Devices' drop down at the top selects which of the 16 devices to work on. For another example that is a little more difficult lets create an accelerometer device. At the top drop down select an available entry ("-Available Device Entry-" will be shown). It doesn't matter which available entry is used. No need for them to be in order or anything goofy like that.

The accelerometer outputs 2.5 volts at 0 G's, then a change of 1 volt per G for a max of +- 2 G's. So -2 G's is 2 volts down from 2.5 volts for 0.5 volts (at -2 G's).

And +2 G's is 2.5 volts plus 2 volts for 4.5 volts (at +2 G's).

So the range is: 0.5 volts at -2 G's, and 4.5 volts at +2 G's.

The User Device set up looks like this:

UserDevice1


Once the various devices are created they are then assigned to an ADC channel via the Preferences dialog.


Preference, ADC Channels:

Assigning devices for data logging is done via the Preferences dialog (ALT-F, F). Then click on the ADC Channels tab. The dialog will look similar to this:

ADCChannels


There are eight (8) available ADC channels on the EBL board. Each of these is labeled on the front edge of the PCB. In the ADC Channels dialog the channels are labeled 0 through 7. These match the labels on the EBL board.

The Device column is used to select the device on that ADC channel. It may be one of the standard built in devices, or one of the user created devices. Note that the same device type may be used on more then one ADC channel. Note the Accelerometer on both channel 2 and 3. This is a two axis G meter (acceleration, deceleration, left corner, right corner).

The Filter column applies a 1st order filter to the conversion. This can be used to smooth the values in the dump file. The larger the % the more the value is smoothed.

The Preferred push buttons are used to select a single WB channel and a single fuel pressure transducer channel. For the fuel pressure it selects which one is shown on the main Wud display (left side).

For the WB, it selects which WB channel information is shown on the Wud, Trip, Diag, and Analysis displays. It also defines which WB channel is used for VE Learns (when learn from WB is selected).

The preferred push button for each device can be turned off by clicking again on a selected button. Selecting another button turns off the currently selected button.

A note about the ADC channel data and logging. The raw ADC values are saved in the data log. It is not until the data log is analyzed that they are converted to a readable form. So if the devices and/or ADC channels are incorrect during logging, they can be changed to obtain the proper results during analysis or playback.

For how the ADC channel data is shown in the Dump Log file (.EBL) see further down in the Analysis Dump Log header section.
