What is new?

SportDyno V3.3

  • TQ and HP peaks filtering (FEB/15/06, release 03) The program detects TQ and HP peaks (when speed changes from 0 to certain value) and removes the peak done for this sudden change.
  • Channel manual boundaries, certain channels are better displayed with fixed upper and lower boundaries. 3.3 version lets the user to setup these boundaries in the channel configuration window.
  • Slip % calculation, the program calculates a slit % ratio from a base value (base ratio) to see how the roller sleeps during acceleration. The program DOESN'T calculate the base ratio, for an accurate ratio the user should do a stationary test without acceleration, to get the ratio when slip% is 0.
  • SP4 support PID configuration window added. For SP4 setup, PID, brake, throttle, etc.
  • SP3 and SP4 load cell setup digital amplifier setup in PID window (zero and scale are now digital).
  • SP4 monitor shows all PID data (target, current speed, current brake action) to ease the PID setup process.
  • Ramp Window Configuration The program lets to automatice the stabilization, load control, acceleration, process to ease repetitive testing with SP4.

SportDyno V3.2

  • Max Speed field added (DEC/5/06, release 029) in configuration window, for Roller Speed Gauge.
  • Record timing in munutes (NOV/30/06, release 028). Record time has been changed to minutes in configuration window, and code has been reviewed to allow more than 10 minutes of recording (as in previous releases).
  • Speed column in printing added (SEP-28-6, release 27). New column in printed/preview report: speed (km/h or mph). Requested by some customers. Not really useful because it depends only on vehicle's ratio. Not the actual speed on track.
  • Disable interpolation option (SEP-28-6, release 27). From version 3.0 new interpolation code was added to increase accuracy on HP and TQ readings at high speed, and to enable the program to work with few pulses. But sometimes it can be useful to disable this code to comparate different gear tooth configurations.
  • Clear commentaries check box (JUL-7-6, release 26). This lets the user to determine wether the commentaries box is set to blank for each new test or the previous text is kept.
  • Channels box has been replaced by a dynamic list(JUN-23-05, release 17). This will enable the program to add more channels to the list as they are being using: from a file from other user with more channels, or from a net of units with more channels.
  • Cursor interpolation (JUN-23-05, release 00017), when moving the cursor in a zoomed channel, the samples of the test can be far one from the next one, this caused the cursor to jump from one value to the next one, without following the channel's line. Now the cursor motion has been interpolated to follow the graph.
  • More info has been added to channel config window (JUN-23-05, release 00017). When moving the cursor slowly across the channel data grid it will displaying some info about its fields.
  • When saving (JUN-23-05, release 00017), if all channels was at the same frequency, the program records exactly the same channel lenght for all of them, in order to keep the compatibility with older versions.
  • After updating Frequency of Voltage values (JUN-23-05, release 00017), the program reads they again from the unit to ensure the unit has received the same values (and they are allowed)
  • Frequency and Voltage values transmission to SP1/SP3 (JUN-14-05). With the new firmware version 4, the SP1 and SP4 modules can acquire a higher frequency at the analog inputs. In addition, the input voltage can be changed from software (in previous versions a resistor has been removed or placed on the board to do this)
  • Gauges window reviewed (JUN-14-05). Gauge control reviewed to display more accurately the scale. In addition, the gauge window isn't a "modal" window, the program can still running (load tests, etc), without closing it. It will serve in a future version to have several gauges windows.
  • Internal data structure changed to allow channels at different speeds (MAY-30-05, release 00015). We are going to send a new FIRMWARE upgrade (from version 3b to ver.4) to enable the SP1/SP3 to do data acquision faster on channels J,K (lambda). Special care has been taken to save the data in the same maner as on older versions when the standard frequency is used to keep the compatibility.
  • Pre-data acquisition (MAY-30-05, release 00015). The recording procedure has been upgraded in order to do data acquisition all time in the gauges window to record some data previous to the starting of the test. In this way the program can draw the exact TQ and HP values at starting of the test and also it can start the test with more accuracy when the automatic start option is used.
  • Test data can be changed on the properties window (MAY-11-05). This version enables the user to change several data from the test at the main test list. But as this list usually only shows some columns, it can be easier to change certain data over the "properties" window. To display this window you can double-click over the HP and TQ values on the list, or you can choose properties option (at the popup menu) with right-click.
  • "Keep colours while loading tests" option added (MAY-11-05). As the test loading order has been changed (now the new tests are loaded/done at first position of the list) the user can chose whether the program will keep the current colour for the previous tests (default) or whether the program should assign again the colours.
  • Ratio calculation while doing a dyno run. When using rpm pickup (ratio=0) the program will calculate the ratio value while doing the dyno run in order to get the actual rpm reading without having to wait to the end of the test (APR-20-2004)
  • Correction factor on gauges screen. Now, you can change the correction factor before doing a dyno run. Changes on this setting only will affect to next dyno runs, but existing ones will remain at their previous state (APR-19-2004)
  • Correction factor per test. Now, each test stores its own correction factor and type at which it was done. When the user changes the correction type at the configuration, the program asks the user if he wants to change the loaded tests or not. In this way you will see the HP and TQ values at wich the test was done, unless you change it intentionally. (APR-15-2004)
  • Added "power at engine" option. The user can choose if HP and TQ at engine are displayed or not, always in brakets.
  • Preset facility added: a preset combo has been added to the channel configuration window to ease the channel setup process. Several configuration has been stored, and more will be added in future for several types of sensors. (APR/13/05)
  • Save picture option added: it is available at the "file" menu, (right clicking) over the curve's area, and at the preview window (here all the preview is saved)
  • Tests order has been changed, now the program places the new files and dyno runs at the top of the list, instead of the bottom as before.
  • "Remove last tests" option has been changed to "max. number of tests" option at the gauges window
  • Correction factors added: SAE-J1349, DIN 70020, JIS D1001, ISO 1585 (MAR/9/05)
  • Channel data interpolation table and options have been added to channel window, to let the user to configure any analog sensor, even non-lineal (like LSM11 lambda), (MAR/7/05)

    First release (FEB-28-2005):
  • Gauge's screen look modified, gauges can be changed by the user
  • Average power option added, and time taken in average area (from starting rpm to ending rpm)
  • Average power utility add to create average test from several tests
  • Autosave option (now it is optional)
  • Test values can be modified directly over the grid (list), properties window has been removed
  • Hide/show option for columns on the grid (there are a lot of columns, and the user can choose wich columns want to see)
  • Time offset has been added to test to enable comparison between tests (the starting point of each test is not always the same)
  • Ratio calculation has been unified (the same ratio for engine or vehicle), now ratio=engine rpm/roller rpm always
  • ZOOM and SCROLL controls has been added, now the user can magnify certain area of the test and move across it
  • Histogram window has been improved for the new ratio formula
