DANAS WSBK Data Acquisition System for alpha Racing Dashboard (Updated 11-15-2015)

DANAS: Data Analisys Software: Download Datalogging Desktop Software

DANAS: Data Acquisition User Manual (I2M): Download Data Acquisition Manual

DANAS: DANAS Multi-platform Java Installer (2.26.54beta): Download Java Installer (Mac) Beta

Danas software developed in Java to be able to analyze data collected from alpha Racing systems from miniLAP to Dasy or Chrome Dashboard. The choice of developing the software in Java makes it compatible with all platforms, whether Windows (Version XP through Windows 10) or Mac (See below for details). 

Apple Mac Users: Please use this procedure to use DANAS:
1.  You have to download version "2.26.54beta" from the our website.
2.  You also need to download the latest Java Development Kit ("JDK") software from Java.
3.  Install JDK first on you Mac
4.  Then install DANAS
5.  Open the Danas folder and double click the Danas.Jar file NOT the Danas.App file.
6.  Then it will work on your Mac (after changing the language setting or "Lingua" to "Inglese" or English in the "File" menu and then restart your Mac. END.

Danas thus allows to open the saved data from these devices and display, for example, the trajectories in the various laps, comparing several laps of the same session or belonging to different sessions or different drivers. Even just using data from GPS alone (miniLAP laptimer) you can see the speed at each point of the track, or you can enter any number of split times in order to understand where you have been most effective and it can extract Ideal Lap time.

The GPS map can be configured so as to have an intuitive representation in color scale of the speed (or of any other channel) at any point of the track. Using the overlap of data on the map Danas will automatically identify the beginning and end of each lap showing for each of them the main data directly over the path (it alternatively it can be set for rectilinear trips).

Starting from the GPS information, from which the leaning angle is also obtained, it is then possible to exploit all the features of Danas adding other acquisition channels such as RPM, the speed or the opening of the gas, all without adding any sensor to the bike. 

With rear wheel speed data and the RPM it is possible for example to draw XY plots and to study the use of individual gears and their effectiveness. The XY plots are fully configurable and therefore allow for increased flexibility in data processing. Using the data of RPM and rear speed you can take advantage of the simulated gear function with which it is possible to study what would be the gears/RPM if you had changed the final ratio (or single gear ratio). This feature significantly reduces the time needed to choose the correct ratio.

If the bike has a fast oxygen sensor installed (or you are using a Dasy-X with integrated lambda sensor) you can use the special functions for the vehicle carburetion. Danas is in fact able to obtain, from the lambda values, the RPM and the throttle opening, the complete stoichiometric tables and to automatically obtain the correction tables to set the control unit. For each cell of the table DANAS shows the points that the software selected for mixture so that they can be displayed on the graph having a 100% control of carburetion performed.

Danas has been further enhanced in recent years thanks to the cooperation with Team Pedercini in World WSBK and WSSTK. Through this collaboration we added features designed to reduce the time spent in data analysis during the practice sessions and qualifying. DANAS graphics of can be completely configured to better suit your tastes, choosing the location and size of the map, time table, charts. You choose how many and which graphics to display and where set it on the main window. Danas also allows you to store twenty complete configurations and recall them with a simple click. Each configuration can contain graphics in several different positions, with scales, colors and different views. In this way it is extremely simple to switch from the study of the parameters to those of the motor chassis very quickly or simply to always have on hand the display that each user prefer.

The tab of session Lap analysis viewer allowyou to have quick analysis of the performances showing for each lap/session the maximum, the minimum and the average of each channel, while a special function allows you to display them on the chart. Through the use of math channels and filters you can make a first mathematical study on the acquired data, if this is not enough Danas allows you to export all data in .csv format so as to be processed by other software.

The alarm function allows to configure some alarm condition that the software will search automatically within the data and that at a first glace may have been missed, such as an alternator not working perfectly, a temperature too high etc ..

The complete synchronization between the graphics and the map and the use of the sliders quickly allows to associate the various data to every single point of the track or to compare values ​​of different points. The delay function instead allows you to view how the delay  compared to a reference lap changes along the path.

Through the use of the DashWare software (free download from www.dashware.net) a video can be realized with the acquired data overlay. The software is compatible with any video and using the protocol developed for the Danas software (downloadable aboave), you can easily import data from .csv exported to Danas. Setting up your own videos with style MotoGP becomes a matter of a few steps. The same result can be obtained from the exported  data with software like TrackVision.

-
Special Notes: You must use Windows XP or Windows 7 & 8 Operating System. Do not use Mac with Parallels. This Tuning Device is linked to your unique VIN Number, and use on a second VIN will require the unit to be unlocked for a fee by the manufacturer. You MUST un-zip the compressed .exe file to run on your desktop. 
-
IMPORTANT: ALL Power Commander PC-V or "Other" Piggy-back tuners MUST be removed from the bike BEFORE you READ the initial OEM file, and WRITE the new Map files. *** Failure to do so could result in permanent damage to the ECU*** The piggy-back devices will never be needed again, and our FLASH Tuning is Fully Adaptive and requires the BMW OEM O2 sensors installed at all times. If they were removed, you MUST re-install them. Please email us the .usr file with the LAST 7 digits of your motorcycle's VIN Number as the actual file name, so as to keep the correct files in our cloud server. Be sure that the PC-to-PG3 is never connected to the Bike-to-PG3 at the same time. Mandatory: Connect a battery charger during the READ/WRITE procedure. You MUST inform us if the ECU has ever been flashed before. If yes, please indicate that on the Tuning Forms so we can flash your ECU on the bench. 
-
When you receive your Powergate 3 Tuning Device you will READ the Original Map File ("ORI") from your motorcycle and email it to us for the creation of your alphaRACE Modified File ("MOD") that we shall send to you by email in 24-48 hrs if we do not have to build a custom driver for your ECU. Each and every BMW BMSK Engine Control Unit for the BMW S1000 RR and HP4 have different Firmware, Protocols and Software that require special modifications and drivers to create your specific bike's "tuning". You must CONNECT a motorcycle battery charger to your battery while performing the functions READ or WRITE from and to your ECU. 
-
Note about the mandatory use of SAS Block-Off Plates: The BMW Secondary Air System ("SAS") is an induction system that burns the unburnt exhaust gases by injecting fresh air (secondary air) into the exhaust ports of the engine, reducing the emission of hydrocarbons. Once these are capped off with the alpha Racing block off plates for the AIRBOX and VALVECOVER, the air injection system can be safely removed. This Block Off Plate is made from CNC billet aluminum, have an OEM O-ring for correct seal and feature the “alpha” logo. There are three reasons why you want to remove the air injection system from your BMW.


▪    1. If you are using your motorcycle on a closed course (racing, track days, etc.) you will want to remove all unnecessary equipment from your bike for reduced weight and ease of maintenance.

▪    2. To get an accurate Air:Fuel (A/F) ratio when you dyno the bike. The air injection system pumps fresh air directly into the exhaust stream in order to burn off any unused fuel. Unfortunately by doing this the A/F ratio is thrown off by the extra "fresh air" in the exhaust stream. By removing the air injection system you can achieve an accurate A/F ratio.

▪   3. This addition will typically remove the majority of popping on deceleration that can be experienced with un-burnt gasses within the emission charcoal chamber. 

If you are tuning your BMW with any aftermarket solution tuner - you need these SAS block-off plates (available in our SHOP).

IMPORTNANT NOTE: BMW Drive-By-Wire (DBW) Throttle advisory.

When you purchase a Clutchless Downshift Blipper Kit System, all customers are required to send alpha Performance the voltage measurements form (directly above) with information filled in according to the voltages from the TPS connector while connected. Also the motorcycle must be in perfect working order with no fault codes present. Once this is completed we build our blipper kit system's stand alone ECU to match these voltages, so it is hand built for each individual vehicle and THAT PARTICULAR TPS SENSOR.

Warning! If you switch or change the TPS Sensor, the electronic twist grip assembly or throttle bodies after you have ordered/received your blipper kit system - there is a very high probability these voltages will change.

We insist that you contact alpha Performance if you make any changes to the TPS, electronic twist grip or throttle bodies where we will ask you to fill in the voltage form once again. We will cross reference the original voltages to ensure that the blipper kit system settings are still compatible with your DBW throttle.

If any voltages have changed, the blipper kit system will need to be returned and checked by alpha Performance to prevent future problems.

alpha Racing Downshift Blipper (V2) INSTALLATION VIDEO SUITE

Section 3. INITIAL SET UP

Press both buttons to enter in the programming.
Push lower button to scroll the menus forward while push the upper one to scroll backwards.
Press and maintain the lower button to enter into the various menus. To exit from the menu and under menus, press upper or both buttons. System will go out of programming if no buttons are pushed except the "r" menu. During programming the quickshifter will not be working.

WARNING: Use only on the following setup options.

3.1 Signal time programming "t" (“Time”).

Set at the maximum allowed value. Upshift timing will be managed by original BMW ECU not by SGRACE. If the ECU requires a different cut time, it can be adjusted within 20ms - 99ms.

3.2 Downshift rpm "rL" (“RPM Limit”).

NOTE: The “Blip” function will not work below 3,000 rpm. Above this limit the timing of the blipper is automatically set in function of customer’s choice. “rL” are the lower rpm limit level.

3.3 Downshift timing "SL" (“Set Limit”).

Set the desired timing of the “blip” at “rL” rpm (see par. 3.2).

3.4 Upshift Pre Load adjustment "L" (“Load”).

Default setting "22" it's possible to change the load necessary to apply on the sensor for the upshift signal. With ignition on, engine off, try to select the upper gear. Shift lever should move through the spring load in gearbox until gear resistance is felt. If rpm is above the set value at par. 3.8, the panel LED should show "--" for a while. If this happen too early or too late consequently change the preload setting.

3.5 Actual Load displaying "S" (“Shift Load”).

Entering into this menu, it's possible to read the actual load value. Useful feature for preload adjustment and for gearbox check and maintenance.

3.5.1 Max Load displaying "--"    (“Max Load Display”).

At this point, pressing and holding the lower button, the display will show blinking "--" for about 10 seconds. Afterwards it will show the max load value registered in this period.

3.6 Downshift Timing "tS" (“Downshift Timing”).

Set the “Blip” timing within 20ms - 98ms at 8,000 rpm. Default 98ms. The blip timing at 12,500 rpm will be 70ms more than this value. In the between the CPU will interpolate the value. We suggest timings between 98 and 80ms. Too much timing allows gear in but then you’ll feel the bike pushing a while. A too short timing doesn’t allow a proper downshift. We suggest to start with high value and reduce it during the tests on road.

3.7 Downshift Pre Load adjustment "LS" (“Pre Load Sensor Adj.”)

At default setting "14" it's possible to change the load necessary to apply on the sensor for having the downshift signal. With ignition on, engine off, try to select the lower gear. Shift lever should move through the spring load in gearbox until gear resistance is felt. The panel LED should show "--" for a while. If this happens too early or too late consequently change the preload set.

3.8 Minimum rpm limit "Sr" (Minimum Shift RPM”)

Set rpm below where the system is not cutting RPM. Visualization: /1000.

3.9 Type of analog output "dS" “(Analog Output”)

If your system has the analog output, this function allows to set the type of output: "dC": 0-5V with 0 load at 2.5V. "dU": 0-5V with 0 load at 5V. "DD": 0-5V with 0 load connection at 0V.

3.10 Lower/Upper limits "dr" (“Limits”)

If your system has the analog output, set "5" = ±50Kg, "10"= ± 100Kg.

3.11 Pushing/Pulling "CE" (“Shifter Orientation”)

Set "C" Pushing, "E" Pulling of the Shifter orientation for STD. of GP Shift.

WORKING CONDITIONS : 8V - 17.5V; -20°C - +95°C.

*** Special Notes for BMW's with ATTACK PERFORMANCE rear sets installed: please use the following settings. These are modified base settings that you will fine-tune as required.***

T=63 upshift cut timing
L=16 upshift pressure
TS=80 blip timing rpm
LS=10 blip pressure

BMW S1000RR aR Dry Slipper Clutch Technical

SPRING FUNCTIONING
Primary spring:
• It makes pressure on the disc pack through the pressure plate;
• It replaces the helicoidal springs
 
Secondary spring:
• it makes pressure on the drum;
• it regulates the opening of the slipper clutch and regulates the engine brake.
 
Spring functioning
The primary and secondary springs are pre-loaded in order to generate an initial elastic strength of contrast.
 
Primary spring functioning
When you operate the clutch lever, the primary spring is compressed. The spring releases an elastic strength of contrast to the lever movement. The next chart shows how the spring load varies with its compression.
 
Secondary spring functioning
The engine brake makes the drum rotate and shift outwards causing the discs to disengage. The secondary spring is compressed in comparison with the initial resting position and generates an elastic strength of contrast. This strength is described in the following graphic.
 
Primary spring load/compression chart 
The origin of axes corresponds to the free height of the spring, i.e when the spring is not loaded. Each mm of compression corresponds to an equal decreasing of the spring height.
 
Secondary spring load/compression chart 
The origin of axes corresponds to the free height of the spring, i.e when the spring is not loaded. Each mm of compression corresponds to an equal decreasing of the spring height.
 
Diaphragm springs and helical springs
Operating the clutch lever, the diaphragm spring is compressed and releases a strength which is constant, if not inferior in the maximum point of the curve. alpha Racing slipper clutches use this characteristics to let the strength  to be done while actioning the clutch lever constant or even inferior. The helical springs usually present in the majority of standard clutches have a curve with a linear increasing chart. When pulling the clutch lever, the helical spring is compressed and releases an increasing strengh. This means that the lever becames harder as you pull the lever.
 
Spring adjusting #1
In case of downshifting or violent hard breaking the rear wheel generates a back torque. This back torque causes the hub to lift up and shift disengaging the discs. The secondary spring contrasts the hub movement.
Secondary spring: its function is to press the drum against the hub. It regulates the opening of the slipper clutch to control the engine brake. According to the load (expressed in kilos) of the secondary spring, the opening of the clutch is anticipated or deferred, that is the opening arrives at inferior or superior values of back-torque. The biker feels it as low gear effect: when the clutch opening is anticipated, the biker will feel less low gear effect; when the clutch opening is deferred, the biker will feel more low gear effect.
 
Spring adjusting #2
The engine brake can be modified according to biker preferences by using a different secondary spring. If the rider desires less engine brake while entering turns, and wants low gear effect we should replace the secondary spring with a lower loaded one (less kg). Street conditions also influence the set-up choice; different set-up can be chosen according to surface conditions: -wet ­-dry ­-mud.
The opening of the clutch also depends on the primary spring: the drum is contrasted by the secondary spring and also by the primary spring when the pressure plate lifts up. The standard set-up of aR clutches should be the ideal one for the most riders, because it results of tests made with the most important teams in many championships. However the spring set-up can be changed according to riders preferences.
 
Differences between 90 mm and 125 mm primary spring:
The main difference is that in the clutch with 125 mm spring, the elastic action of the spring is applied right on the disc pack. With the 90mm spring the pressure is not direct on the plates, because the spring is positioned in the centre of the clutch. The advantage of 125 mm spring is to give a softer clutch lever, being equal the pressure on the plate pack. The slipper clutch with a 125 mm spring is an evolution of the 90 mm spring, that is still supplied.
 
 
aR SLIPPERCLUTCH TYPICAL FEATURES
 
Lever ticketing
Clutch lever ticketing is due to the action of the clutch pusher plate, in the moment in which it is raised under the drum pressure. In this case the rider’s fingers can feel a small ticketing, indicating the slipper clutch system is working correctly;
 
Racing pumped engines
In order to use aR slipper clutch on “non standard” engines, with more hp and torque, it is advisable to fit the clutch with a primary spring more loaded (+ 10 kgs.). This to avoid clutch slipping in starting phase.
 
WHY TO USE alphaRacing SLIPPER CLUTCH
Road use:
Prevent engine overturning;
Prevent rear wheel hopping;
Enable the downshifting without use of clutch lever;
Enable the controlled sliding of rear wheel;
Manage clutch lever release, in order to avoid unsaddling;
Allow a better clutch lever release in starting phase, due to the diaphragm spring.
Off Road use:
Prevent engine overturning;
Prevent engine components integrity, gearbox first;
Avoid engine turning-off due to the holes in the track;
Allow a better jump preparation;
Set the shock absorber more easily and efficiently;
Determine a better drive feeling with the motorbike;
Allow a better clutch lever release in starting phase, due to the diaphragm spring.
