Racelogic Ltd Introduction Congratulations on your purchase and welcome to the worldwide DriftBox community. Drifting With your DriftBox you will be able to display and log your drifting performance. DriftBox also generates a performance related Drifting Score, which you can submit to the DriftBox website for inclusion in the worldwide DriftBox drifting league tables. See how your skills compare to other DriftBox users from around the world at www.driftbox.
Racelogic Ltd Introduction Lap Timing Displaying your Lap times as you drive around a circuit is simple with DriftBox. You can display your last and best Lap times and Lap count, and also display split times for up to six specified split points around the lap. Through the DriftBox website and forum you are able to download circuit overlays from around the world, compare lap times, and share lap overlay data with other users.
Racelogic Ltd Introduction Power Calculations DriftBox can help you to measure the power developed by your car‟s engine, either at the wheels or flywheel. Having set the vehicle weight, results are calculated from the measurements taken by the fast GPS engine to give you useful guidelines to the car‟s brake horsepower or kilowatt output. Because these calculations are made from the GPS data rather than accelerometers, your results are likely to be more consistent and accurate.

Racelogic Ltd Drifting Drifting DriftBox is the first performance meter to measure Drift Angle. A car is said to be drifting when the rear wheels have a lateral (sideways) motion in relation to the road as well as a longitudinal (foreaft) motion. In fact, the moment a car starts to turn a corner, the rear wheels need a certain amount of side-slip to go around the corner, even if you are going very slowly.
Racelogic Ltd Drifting Power Oversteer (FR) In a powerful car, flooring the throttle whilst turning the steering will cause the rear wheels to start spinning, which will reduce the amount of grip at the rear end, causing the tail to try and overtake the front of the car. Applying opposite lock on the steering, and then modulating the throttle to keep the rear wheels spinning is the method of controlling this situation.

Scores can be sent to the DriftBox website for publishing on the Top Scores database. By default, Drift Mode is enabled however when Predictive mode is enabled, Drift Mode becomes disabled.
Racelogic Ltd Drift Mode Drift Mode Display Screens DriftBox has three different screens, available in each mode, which are selected by using the ▲▼buttons. This screen shows speed and drift-angle in real-time, as well as the peak drift angle achieved. Holding the reset button for 1.5s will reset the peak drift angle. Practice Mode Only This screen shows the peak drift angle, the speed at which it was achieved, the maximum lateral acceleration achieved, and the score awarded by DriftBox for the run.
Racelogic Ltd Drift Mode Sectors A sector is made up of two virtual gates. If you have enabled Sectors Mode, the measurement process starts at the first gate, and ends at the second. You can have up to 6 sectors defined, and you will be awarded a score for each sector along with a cumulative score. You do not have to have all 6 sectors defined, you can use just one if required.
Racelogic Ltd Drift Mode Loading and Saving Sectors After creating sector information in your DriftBox you can then save this information to a sector file on the SD card. This allows the sector information to be copied onto your computer and used in the DriftBox software when you analyse your logged data. The sector file will be named DBOX.sct – this is the only file name that DriftBox will recognise as a sector file (see page 57 „Defining Drifting Sectors in DriftBox Tools‟ for further details.
Racelogic Ltd Performance Mode Performance Mode The Performance mode is used to measure the acceleration and braking performance of your vehicle. Press the MODE button to scroll to the Performance Mode screen. This mode is divided into six screens, each of which displays different performance data. Navigate between these screens by using the▲▼buttons. Each screen will automatically display the results as they happen, e.g. if you drive from 0 Mph to 60 Mph then the 0-60 section will show the time taken.
Racelogic Ltd Performance Mode This screen shows the time and end velocity of two userconfigurable distances, i.e. 0-100m. If the units are changed to feet then the two test ranges default to 60‟ and 330‟, but can be changed to the desired distance. This screen shows the time and end velocity of two userconfigurable distances, i.e. 0-400m.

You can make the DriftBox start all timing runs from 1 foot by enabling this feature. Enabling 1 Foot Rollout correction Press the MENU button to enter the Performance Menu.
Racelogic Ltd Laptiming Mode Laptiming Mode DriftBox can be used to measure lap times by storing the position of a virtual gate and using this to trigger the start and end of a lap. Further locations can be added to represent split and dedicated finish lines. Start/Finish Line: Defines the point at which one lap ends and another starts. It also defines the start of a test that ends in a different location, such as a sprint or slalom stage.
Racelogic Ltd Laptiming Mode Lap Count A count of the number of completed Laps is displayed in the top left corner of the Lap timing screen. To reset the Lap count and the Best Lap time, press the RESET button. Lap Timing Including Split Points This method allows for the setting of a start/finish line, up to six split points, and a separate finish line if the course being driven is of a sprint or hill-climb type.
Racelogic Ltd Laptiming Mode Split to Split Time There are two different ways of measuring split times. The default is from the start of the lap to the split, the other method is from one split to another. To change between these options, tick or untick the option „SPLIT TO SPLIT TIME‟ in the DISPLAY OPTIONS menu.

Racelogic Ltd Laptiming Mode When this screen shows you can then start your lap. Timing of your lap will start as soon as you pull away and will then stop as you cross the start / finish line at the end of your flying lap. Start / finish and split lines Before DriftBox can measure and display times, you will need to either load previously recorded start / finish lines or create new ones in your DriftBox.
Racelogic Ltd Laptiming Mode To Save the lines you have created: Ensure the SD card is inserted. Press the MENU button to enter the Lap timing menu. Highlight the SAVE SPLITS option and press OK Loading start / finish and split Lines You can load start and split line information from a file stored on the SD card into your DriftBox. By default the DriftBox looks for a file it has saved out; DBOX.DSF in the „DATA‟ directory. If no DBOX.
Racelogic Ltd Laptiming Mode In each file, the best lap is indicated with an asterisk. To change the lap for which split times are displayed, use the▲▼ buttons to scroll between the laps; the split times will update automatically. Pressing the OK button in this screen will return you to the Lap Timing Mode‟s main screen.
Racelogic Ltd Laptiming Mode Laptime File Error If a file that does not contain any valid lap data, for instance if the car has only moved a few metres, then DriftBox will display this screen: Using a computer to review lap times Any of the „Laps-xx.txt‟ files can be opened using a text editor program such as notepad.
Racelogic Ltd Predictive Mode Predictive Mode Predictive mode enables you to graphically view your predicted lap time. Predictive lap timing works by saving your position around a circuit, every second. If the current lap is the fastest so far, then this positional data is saved as a reference. With just one button push of an arrow key, you are able to set a start/finish line within predictive mode. Please Note; this will overwrite a start/finish line set in Laptiming mode.
Racelogic Ltd Predictive Mode Once a valid reference lap has been created or loaded, the DriftBox will begin predicting. The prediction is shown in text and graph format which is a graphical representation of the amount of time gained or lost around the lap. When a lap has been completed, your lap time is displayed for five seconds before reverting back to the prediction screen. Fixed Lap In predictive mode your reference lap will change if it is faster then the previous.
Racelogic Ltd Speed Display Speed Display Mode The Speed Display Mode is divided into three screens. The first contains a compass and current speed in a large font, and will also give on-screen and audible notification of Points of Interest. The second is an Odometer and the third an Altimeter. Navigate between these screens by using the▲▼buttons.
Racelogic Ltd Speed Display Odometer In the Speed Display Mode pressing the ▼ button selects Odometer Mode. The total distance travelled in feet or metres (depending on units selected) will be displayed in the main window. Pressing the „RESET’ button resets the Odometer back to zero. Altimeter In the Speed Display Mode pressing the ▲ button selects Altimeter Mode. The current altitude in feet or metres (depending on units selected) will be displayed in the main window.
Racelogic Ltd Power Mode Power Mode Your car‟s power output can be measured using the Power Mode. There are two parts to this process: the acceleration run, which gives you the power at the wheels minus the losses caused by tyre and air resistance. The second part of the test measures these losses and also estimates gearbox losses. The Power Mode is also an additional tool for car tuning, where access to a chassis dynamometer is not possible.
Racelogic Ltd Power Mode Power Runs Once the vehicle weight has been set, a simple power run can be carried out to give engine output at the wheels. Put the car into second gear at a low RPM, 2000 RPM or less.
Racelogic Ltd Power Mode Begin to accelerate, and press OK. Continue to accelerate to the top of the engine rev range. At the top of the rev range, disengage the clutch and put the gearbox into neutral.
Racelogic Ltd Power Mode Input Module Screen The Input Module screen provides the ability to configure the input and output channels of a connected Micro Input Module and view the data on each of the input module channels. NB: This mode requires the RS232 chip upgrade in order to function. Input module connection The DriftBox connects to a Micro Input Module using an RLCAB094 cable plugged into the Auxiliary connector on the back of the DriftBox to the DATA socket on the Micro Input Module.
Racelogic Ltd Data Logging Data Logging Providing that you have registered your DriftBox (see Quick Start Guide) then it will be capable of logging data to an SD. Using the SD Files logged by DriftBox are named „DBOX_001.dbn‟, where 001 increments when a new file is created. A new file is created every time DriftBox is powered up, or when the card is re-inserted. If you wish to log data to the SD card then simply insert the card into the slot in the front of DriftBox.
Racelogic Ltd Connecting DriftBox to external devices Connecting DriftBox to external devices Drift Data output DriftBox transmits live data on its serial port at the rear of the DriftBox when it is in Drift Mode. Any other devices with a serial input, such as a video overlay unit, can use this data. A serial output cable will be required (part number RLCAB032), please see the DriftBox website or contact your local supplier for details.
Racelogic Ltd Upgrading Firmware Setup Menu There is a single Setup Menu that is accessible in all of the DriftBox‟s modes.
Racelogic Ltd Upgrading Firmware Diagnostic Screens DriftBox has two different diagnostic screens, use ▲▼ to swap between the two. GPS Diagnostic Screen This screen allows you to view the following basic GPS information: Number of satellites being used by Latitude. DriftBox. Longitude. Signal strength of each satellite.

You are able to select the current Comms Mode in the Comms Mode submenu of the Setup menu. The default mode is input module. COMMS MENU INPUT MODULE LAPTIME TELEMETRY LAPTIME PULSE DRIFT TELEMETRY YAW DIAGNOSTICS EXIT Input Module Sends an input module firmware version request at about 1Hz until a response is received.
Racelogic Ltd Upgrading Firmware Upgrading the DriftBox Firmware It may be necessary in the future for you to perform an upgrade to the firmware inside your DriftBox to add new features. Connect your DriftBox to the computer onto which you have installed the DriftBox software. Download the upgrade file from the website and save it to your computer. Press and hold the MODE button whilst you connect power to your DriftBox. This will force the DriftBox into Upgrade mode.
Racelogic Ltd Troubleshooting Troubleshooting My DriftBox does not pick up or lock onto satellites Some modern cars are fitted with a special windscreen that cuts down the amount of UV (Ultra Violet) rays that will be transferred through the windscreen which help cut down on glare.
Racelogic Ltd Troubleshooting DriftBox displays an angle > 10o when the vehicle is not drifting Check the „Alignment‟ of the DriftBox; see the alignment section of Setup Menu in this manual for further information. If the road has a severe camber / gradient this will slightly affect the Drift angle calculation. If you are in an area of poor reception quality then this will affect the Drift angle calculation.
Racelogic Ltd DriftBox Tools Software DriftBox Tools Software The DriftBox Tools software allows you to view the driving data recorded by DriftBox in a „.dbn‟ file. The software also allows you to display Lap times, Acceleration, Deceleration and Drift results, and to carry out detailed analysis of driver and vehicle performance. Installation Each DriftBox is supplied with a CD containing the DriftBox Tools software. Insert the CD into your computer, the installation should then auto run.
Racelogic Ltd DriftBox Tools Software Graph Window In the Graph window different channels can be plotted, either against time or against distance, and up to four „.dbn‟ files can be overlaid on the graph. The Graph window can display large amounts of data at once, with the addition of various axes to aid analysis. Graph: Map Window The Graph: Map window shows the path of the vehicle, calculated from the latitude and longitude data.
Racelogic Ltd DriftBox Tools Software Data Display Once a file has been loaded the three windows will each display some information, as described in DriftBox Tools Windows on page 45.
Racelogic Ltd DriftBox Tools Software moves through the file one sample at a time (one-tenth of a second.) The cursor can also be placed in the graph window by left-clicking the mouse button at the desired cursor position. Zoom Zooming in on the data in the graph or map window can be done three ways. Use the left mouse button to click and drag a window from left to right around the area of interest. Click and drag from right to left to zoom out.
Racelogic Ltd DriftBox Tools Software Additional File Functions By clicking on the small arrow next to the Load All button, a further set of file-loading options is revealed: Load Compare File The Graph screen has the facility to load up to three more files for comparison.
Racelogic Ltd DriftBox Tools Software Editing DriftBox Files Sections of a DriftBox file can be removed using basic editing commands accessed through the „Edit Data‟ icon in the Graph screen toolbar. Note from the screenshot below that each editing function has a keyboard shortcut. Cut All Data before Cursor This feature removes the entire file up to the cursor position in the main memory (ie not any compare files currently loaded) only.
Racelogic Ltd DriftBox Tools Software the image to export. A dialogue box will appear that will allow you to choose several factors, including the format in which you wish to export the file: Selecting Channels All channels logged by DriftBox appear in the data window; all except speed are initially greyed out, but the data can still be seen. To enable a particular channel and make it visible in the Graph window, click in the tick box to the left of the channel name.
Racelogic Ltd DriftBox Tools Software A channel can also be found by typing the first letter of the channel, for example ‘S’ for Satellites, providing that the data table is the currently active window. If there is more than one channel that starts with the same letter then press the key again until the software stops on your desired channel.
Racelogic Ltd DriftBox Tools Software Channel and Axis Setup For each channel there are a number of attributes that can be configured, including those relating to the y-axis. These are configured in the Channel Set-up and Axis Set-up screens, which are accessed by double-clicking on any of the channels in the data table or by right clicking the mouse button and selecting the „Channel scaling & Axis setup‟ option, or by clicking the „Graph Set-up‟ icon on the Toolbar.
Racelogic Ltd DriftBox Tools Software The example on the right shows the Lateral Acceleration channel with a smoothing level of 2. This example shows the Lateral Acceleration channel with a smoothing level of 25 – note how the individual peaks and troughs are no longer present, so the true dynamic values of the vehicle are now not shown. Smoothing Level should therefore be carefully applied – too little and the data can be too „noisy‟ for easy analysis; too much and valuable information can be lost.
Racelogic Ltd DriftBox Tools Software Run 1 This column shows the selected colour for each active channel. To change the colour click on the colour box of the channel and select a new colour from the colour selection box that appears. The colour chosen will also be applied to the axis, should this be selected; for example, if the Lateral Acceleration channel is used in green, so too will the Lateral Acceleration axis, if it is used.
Racelogic Ltd DriftBox Tools Software Min / Max The Min and Max boxes allow the scale ranges for each axis to be set. Autoscale The autoscale option causes the axis scales to automatically fit the minimum and maximum values of the loaded channel. Symmetrical This option will cause the positive and negative maximum values on the axis to be the same magnitude. The magnitude of these will be determined by the largest positive or negative value of the channel.
Racelogic Ltd DriftBox Tools Software Analysing Your Data in DriftBox Tools DriftBox Tools has three main features which will allow you gather results from data you have logged. Many of these results are available to view on the DriftBox itself, but the software allows for more detailed analysis and the replaying of data. This section is divided into three subject areas: Drift Results, Lap Time Results, and Performance (ie Accel/Decel) Results.
Racelogic Ltd DriftBox Tools Software Sectors Before you can display any Drift results you need to set up sectors. Defining Drifting Sectors in DriftBox Tools Each sector that you set requires that you define a start line and an end line. Each sector is numbered from 1-6. Setting sector Start Move the cursor in the Graph window to the start point of the sector.
Racelogic Ltd DriftBox Tools Software Displaying Drifting Data from a Logged file. Click the Load all button to load a DriftBox file into the DriftBox Tools software. Set up sectors as described above, or load a sector (.sct) file. Press the Drift Mode button to scan the file and display results. Replaying DriftBox Data A DriftBox file can be replayed at real time speed, or at 2 x or 5x real time speed.
Racelogic Ltd DriftBox Tools Software Lap Timing Pressing the Lap timing button in the Toolbar causes the software to scan the loaded file and apply loaded split file information to produce a table of Lap times, with a V Max for each lap and with the fastest lap highlighted. This facility also allows individual laps from the loaded file to be loaded and compared in the main Graph window. In addition a circuit overlay can be loaded into the Graph:Map window to aid with drive-line analysis.
Racelogic Ltd DriftBox Tools Software Start / Finish Lines and Splits Before you can carry out any lap time analysis you must set a start / finish line in the file you have loaded. The information pertaining to these points can be saved to start / finish files for later use with new data from the same circuit, or for sharing with other DriftBox users.
Racelogic Ltd DriftBox Tools Software Loading and Saving start / finish line and split data Click on the „Save‟ option from the start/finish drop down menu to save to the start / finish and split line information created in the Graph screen to a „.dsf‟ file. If you want to save more than six splits for software use only then choose the file type „.spl‟ instead which is only compatible with the software and not DriftBox itself. Click on the „Load„ button in the Start/finish drop down menu to load in a „.
Racelogic Ltd DriftBox Tools Software The circled area circled in green shows two sections of track passing by each other by only approximately 20m. If a split point is set on this section, and the virtual gate has been set too wide, the split point could be registered by the DriftBox as it passes by in the opposite direction. Track proximity can be checked in Google EarthTM using the measurement tool if you are in doubt as to how wide the split points should be created.
Racelogic Ltd DriftBox Tools Software Naming the split files (see „Split Names‟ above) from the option in the „Start, Finish & Splits‟ menu will result in the split names being displayed when the „Lap Timing – Split Line‟ option is chosen – see the example on the next page, which shows the split points that have been set on corners at Silverstone Circuit and named accordingly.
Racelogic Ltd DriftBox Tools Software Loading and comparing individual laps from the same file Individual laps from the loaded file can be compared to each other in the main Graph and Graph:Map windows. Each lap shown in the Lap timing table has a Graph Icon associated with it in the right hand column. Clicking one of these buttons allows that lap to be individually graphed: You will now have one individual lap displayed in the Graph window, and one corresponding column in the Graph:Data window.
Racelogic Ltd DriftBox Tools Software Result in the Graph window: The main run is in red, the compare run in blue. In this instance the two laps have been performed very consistently: the peaks and troughs, which indicate the braking and acceleration points, sit on top of each other almost every time. Note that the Graph window‟s X axis is set to distance – this makes direct comparison of braking and acceleration points possible as the distance covered on each lap will be virtually identical.
Racelogic Ltd DriftBox Tools Software Load the next file to be analysed – ensure that the results from the first file have not been cleared, and do not load the second file as a compare file. Click the laptiming button again and the second set of lap times will appear in the results window.
Racelogic Ltd DriftBox Tools Software speed plots, indicating that the faster driver carried more speed before braking, and accelerated harder.
Racelogic Ltd DriftBox Tools Software Replaying Laps If you have recorded laps loaded into the software you can replay them, by clicking on the Replay button. By default the cursor will move through the Graph window and round the path in the Graph:Map window at the same speed at which the file was recorded. However by clicking on the arrow to the right of the button a faster replay speed can be chosen.
Racelogic Ltd DriftBox Tools Software Circuit Overlays A circuit overlay is a file created to map the outer and inner bounds of a circuit, and is a useful aid in drive-line analysis - comparison of lines taken by different drivers can help to improve lap times.
Racelogic Ltd DriftBox Tools Software If you want to load a .cir file into DriftBox Tools on its own, click Load All and then type *.* in the File name field: You can then select the .cir file and it will load like a normal .dbn file. A library of circuit overlay files is available from the DriftBox website. If you would like to share circuit files you have created please contact us and they will be added to those already available.
Racelogic Ltd DriftBox Tools Software In order to be able to view truer drive lines, right-click on the Graph Map - the option to align either the lap data or overlay will appear at the top of the context menu. Having chosen which you wish to move in the “Select run to align” dialogue box, use the keyboard cursor keys to realign either the circuit overlay or lap data. Once you are content that the drive lines resemble the actual lines taken, press return.
Racelogic Ltd DriftBox Tools Software Importing a background image in to the Graph Map You can import any image of your choosing into the Graph Map by right-clicking on either the Graph:Data, Graph:Map, or Graph windows and selecting the Graph: Map Background Image>Load option: - 77 -
Racelogic Ltd DriftBox Tools Software Performance Results Acceleration and deceleration results can be easily extracted from your logged data by using the various performance results tools. These are available by clicking on the „Accel results‟ and „Decel results‟ buttons on the Toolbar. You can extract speed or distance data for acceleration and deceleration runs. Most of the tests use standard parameters (such as 0-60 or 0-100) but custom results can also be produced.
Racelogic Ltd DriftBox Tools Software Creating a Custom Acceleration test 1. Click on the Custom option in the Accel test drop down list. This will then open the following window: 2. Enter the speed of the start condition. 3. Set the end condition option, speed or distance. 4. Enter a value for the chosen End condition. 5. Press Scan to scan the loaded file and produce a table of results for all tests fitting the custom test setup.
Racelogic Ltd DriftBox Tools Software Additional Data Analysis Features The software has additional features to aid in data analysis, explained in this section. Many of these features can be used as a part of the analysis whilst producing either Drift, Lap or Performance results. The G-Circle Pressing the G-Circle button produces a plot of the Longitudinal vs Latitudinal Acceleration data. A G-circle (or G-G Plot as it is sometimes known) gives a complete overview of how the tyres are being used.
Racelogic Ltd DriftBox Tools Software Graph Measure Tool This tool can be used to highlight a section of data in the Graph window and produce a table that summarises the data captured in the window: Measure Window Summary box Hold shift down whilst clicking and dragging to use the Measure Tool The area of data that is displayed in the table is highlighted in blue in the Graph window. This is often useful for quickly establishing average values between two points in a file.
Racelogic Ltd DriftBox Tools Software Event Marking Event Marking allows for the Brake Trigger channel to display a change in state – an „event‟ in a logged file which can be useful for measuring distances etc. The Brake Trigger channel defaults to a value of 0, until the an event is marked (see pages 22 or 31) at which point the value will become 1.
Racelogic Ltd DriftBox Tools Software Tools Clicking on the „Tools‟ icon on the Toolbar will reveal a drop-down list containing a number of useful features, such as File Repair and the Exporting Data to Mapping Software facility. Arrange Windows The use of different screen resolutions or multiple screens can cause DriftBox Tools windows to be placed out side of the default screen size, which is then not viewable when the default screen is used.
Racelogic Ltd DriftBox Tools Software open it, then select „Comma‟ as the delimiter and click „Next‟. In column F2 select Latitude as the column name from the drop down menu. In column F3 select Longitude as the column name from the drop down menu and then click „Finish‟. The program then generates a map of your data location and places markers on the map at every data point that was specified when the output file was, for example once every second.
Racelogic Ltd DriftBox Tools Software Radius of Turn set-up Click this option to open the Radius of Turn setup window, in which the smoothing level and maximum radius value can be set. When smoothing is applied to data, the value of an individual sample point is affected by samples around it. As the effective Radius of a straight line is infinite, the very high samples of data before and after a corner can adversely affect the values of Radius in a corner.
