  1. Introduction The data logger is build into the PCMTEC editor, and allows you to seamlessly log your vehicle, and switch between the Nagivator and Flashing windows during a logging session, and then continue logging after reflashing and restarting the vehicle. Once the Datalogger windows is opened, and the vehicle ignition turned on, the data logger will automatically connect to the Vehicle PCM: Vehicles with a ZF automatic transmission can connect also the the transmission, using the 'Trans' button External logging for recording AFRs, boost pressure or other user defined variables can be done using the DLP IO8-G Analogue/Digitial converter. This is covered in another HOWTO here Selecting Channels Use the Channels tab to select which Scalars you wish to view in the chart. Whilst the chart itself can display upto 16 channels (comrised of 4 charts, with 4 slots per chart), extra channels can be logged and saved and reviewed later on. These can be selected live whilst connected to the PCM and TCM (ZF) and are then added to the logging session. Clicking on the Scalars tab displays the currently selected items. Anything greyed out is not displayed on the chart, but can be added using the right click menu Allocating Chart Items Right click and select a Chart item to allocated TQ_ETC_SRC to Chart 4 / Slot 1 for example Otherwise use Multi Chart add to quickly add to the next available slot (if any are available) That now displays in our chart Using Scalar Delete will remove items from the chart, but they will still be recorded as part of the logging session Using Chart Remove will free up the slot on the chart, but keep logging it and displayed in the Scalar section (greyed out) Adjusting Ranges There are several methods to adjust ranges of scalars from their defaults: 1. Right click Scalar and adjust range 2. Click and use the Zoom +/- buttons 3. Hover the axis and use the mouse scroll button, and adjust by hold and move up / down 4. Otherwise click the axis and use CTRL PAGE / CTRL DOWN keys Use the PAGE UP / PAGE DOWN keys to adjust the position of the axis 5. Right click the axis and adjust the range using the window All range adjustments are saved, and can be stored in the save Layout feature Sorting Scalar items list By default all items are sorted into their 'parent' groups, matching the Channel tree. If you Right click and disable 'auto sort' you can custom configure the ordering of the 'Scalars list' Here I used CTRL UP and CTRL DOWN to move the scalar items with all temperature scalars positioned together Enumerated Items Some chart items like FUEL_SOURCE and TQ_ETC_SRC have meanings attached to the values, these are enumerated items. You can display the raw value by unticking the Enumerated tickbox Update rates Whilst there are no limitations on the number of channels you can log, on BA all channels will be 'polled'. Adding more channels will gradually reduce the update rate. On vehicles BF upwards, rapid packet reading is available for upto at least 15 DMRs and then polling available on top of this. If one of the channels you have selected requires a faster update rate, it can be forced to use rapid packet by selecting High Priority for that channel The priority tickbox (left of the Scalar name) will be enabled for those High priority items you have selected. If none are selected then at least the 15 first DMRs in the list will be used for rapid packet. Layout Load / Save Use the Save / Load / Load append layout buttons (also available from the File menu) to keep a copy of your current chart configuration, including the items ticked, their chart slot and their ranges Load append will add extra chart items to your current chart (ticked and their position if available) if they were not ticked previously. Note: Where a slot is already used, these will be ignored and not displayed Layout files are saved in the PCMTec/Logging layouts folder, and saved as TLO files Pause / Start / Clear buttons During logging you can pause the live log updates (logging will still happen in the background) and then review your current log by moving the blue cursor You can drag the cursor with the LHS mouse button and moving the mouse, or using the LEFT / RIGHT cursor keys. Holding the cursor keys will flip through the log page by page as it scrolls through the log. The legend/scalar values will update showing the current values at the cursor, even during a live logging session. Clear button will clear out the current log. If the logging is over 10 seconds then you will be prompted if you want to keep the log. Logs are auto saved in case you wish to retrieve something later, then check out the auto save folder Loading and Saving Logs Use the Save icon to save your log as a TECLOG or CSV file (for loading into other software like MegaLogViewer for example) Open the file will start in the PCMTec/Data logs folder, where your save files are located CSV files from PCMTEC as well as other Ford tuning software export CSV format, are supported by the data logger for playback mode In playback mode, you can press Start to begin playback, and pause to stop. Display Options Smoothing: is on by default and will remove some of "stair casing" of the chart data Auto range: is off by default. This will adjust the chart range based on what has been logged so far (or the range during playback). Turning on will adjust the range to fit the current screen you see: Auto scroll: will stop the chart scrolling if unticked Legend: when unticked will hide the legend window if required Adjusting units Units must be adjusted whilst the PCM is disconnected. When doing this, the charts will be auto scaled to the new units type (for example from deg F to deg C) Either adjust individually, from the Units dropdown: Or adjust everything from bulk change: Zooming The time axis can be zoomed in and out using the scroll wheel on the mouse, when hovered over the main chart. Either zoom to the Left or Right hand side of the chart, upto a maximum of 1/8 second zoom level. Using the keyboard, using UP and DOWN arrow keys will also perform similar zoom functions Full short cut keys are available with F1 or the Shortcuts icon Full short cut keys descriptions are in this HOWTO
