Hi everyone. I'm wondering what's out there in the way of datalogger usage instructions. I've been spending more time getting to know it and working out practical ways to help riders improve. Aside from the obvious manual, are there videos or resources that have been gathered up over time?

I have some things I was thinking about sharing but don't want to be redundant, and want to see what other knowledge exists.

I spent two days in a training class with a BMW race engineer going over the S1000RR, datalogger, and RCK3 which gave me a deep look into how these systems work together. I feel the datalogger in particular, with some basic training, can be pure gold for a rider.

There is not anyone else that I have seen post on here they have attended a 2 day training course on HP products. There is other threads with some postings with questions, but, not very many good answers.

so please feel free to express what BMW engineering product support has to offer on the integration and usage of RCK3 and HP Datalogger.

We I think the first place to start is at the beginning--meaning setting it up. I have outlined the first steps below so someone can at least get properly started.

Note: if anyone finds an error, pm me and I will edit the post. I'd like avoid bickering on the thread.

Steps to get started with your datalogger if you are riding on track:

​
1) Install datalogger on bike. Lift off passenger seat and plug in per manual. One plug and you're done.
2) Install software and check for updates TWICE on computer.
3) Plug in a "FAT 32" USB drive, then turn bike's key on. (Drive's "properties" will say if it is FAT 32).
4) Light solid when reading/writing, remove when steadily flashing. May read/write twice.
5) Put USB drive in computer, open USB and there should be a file on it now: "2D-Datarecording".
6) Open BMW HP Race Datalogger program. Click "Import log data"--> check "Start HP USB Stick Scanner with Windows" and also check "Start Analysis automatically after log data import" unless you specifically don't want to. Also check "Race track" at the bottom of the page.
7) Go to OPTIONS-->DATA NAME-->check box for "from date and time".
8) Go to OPTIONS-->HP RACE DATALOGGER SETTINGS-->RENAME HP RACE DATALOGGER--> then name it e.g. "Billy's Bike".
9) Go to OPTIONS-->SET RACE MODE.
10) Go to OPTIONS-->CHANGING HP RACE DATALOGGER DEVICE SOFTWARE-->then choose your year model. Each model year shows with an alternate choice of 2D extension box. Don't check 2D extension box unless you have installed an additional box bought separately from 2D that is used to connect an exhaust sensor and other accessories.
11) Remove the USB drive and bring to your bike--but don't turn the bike on.
12) With the bike turned off, plug in the USB drive, THEN turn the bike on.
13) Wait for the solid light to end and you see steady blinking.
14) Pull USB out, does not matter if bike is on or off. Set it aside.
15) Go ride, come in, shut bike off.
16) Put USB into bike, turn it on, wait until light goes from solid to steadily blinking, remove USB, turn bike off.
17) Memory of the bike's datalogger has been transferred to the USB. Datalogger memory has now been cleared--it's on the stick now.
18) Take to computer, open program and data will upload automatically, depending on settings. If no auto upload, "import log data".

One of the really important things that you should do when looking at the data is set the start finish line of the track with a GPS location. Without this start point you don't get lap times and most of the data analysis tools won't work correctly. I struggled with this for quite some time with my data. The data was there but I could not utilize any of the analysis tools within the software.

I considered writing a guide for this myself as the provided instructions with the datalogger aren't the greatest. Of course I got side tracked on other things and also did not see a lot of people really using the datalogger.

I tried to get some people to post about the inner workings of the DataLogger data. That thread dead ended

http://www.s1000rrforum.com/forum/b...gger-configuration-operation-help-thread.html


Then there was another thread on DDC and data logging

http://www.s1000rrforum.com/forum/s...s-wheels/133617-data-logging-ddc-signals.html

So, you went to school on it. Please feel free to share what the school presented on it.

 

[Dylan Code]

Tomorrow I go off to do 16 school days at the track in three states over four weeks. Thunderbolt, VIR, COTA, and back to Thunderbolt. Meaning I'll be busy. However I will be playing with the system as much as possible and during that time I will see what sort of ideas I can develop around doing a video tutorial. My main focus is to help people "get up and running" with the system: properly set up, start/finish line created, and seeing the data traces of what's happening when they ride.

The best source of information is 2D website itself. Since our BMW datalooger is a so called USB Stick logger with 32MB internal memory and internal GPS antenna you can download the full software version manual and also the USB Stick loogger spec/manual.

But all this is just a description of how to use the software/hardware. It doesn't tell you anything HOW to interpret the data but there lies the real knowledge and expereince :nerd:

This information is widely spread and there is no how-to guide available in comprehensive form. But with the BMW logger are coming plenty of templates you can use for each area to analyse DTC or even your fuel map if you also get the lambda probe and the extension box!

 

[DrIoannis]

Data logging is the best way to understand your mistakes in the track. You can "see" what was the mistake and correct it. You can also see where you loose or win time. If you have lambda sensors or potensiometers, you can tune your engine and your suspension. It's a new way of understanding riding.

But...you also need to understand the data you collect. You need to study. Everytime I come back from the track or a small drive to tune AFR I spent time to study the data. And when I say time I mean hours and hours. There are soooo many data and sooooo many things to understand and "discover". Just think that a team has more than 2-3 people just for telemetry.

A site that might help to start is http://www.datamc.org

 

[AndyHP4]

Totally agree and on top of that you need to know the sweet spots of suspension travel, suspension speed, DTC intervention at which speed and so on.

I am a novice in data logging as well, but here are some tips to start with, which improved my lap times a lot:

The most important thing is that you can compare 2 runs. Preferably is to have a better lap from a friend, or lend the bike to someone to ride it for a few laps to have a fast lap time log.

To start, open the fast lap and then your lap and select on top "Compare 2 runs"
From there I personally select the next channels from the dropdown menu:

Brake_press_f
Gear
Grip_pos (position of the hand on the acceleration)
Speed



from here you can:

1. Plot the laps by distance or by time. One helps to see where you make mistakes on each corner, while the other shows you where you lose most.
2. You can stretch a lap to fit the screen for optimum visualisation
3. Synchronise the 2 logs
4 and 5. I saw that grip position helps the most, as it shows where you start to open the gas compared to the faster lap, when you hit the 100% (or when you should), and when you let go of the gas.

Also you can zoom to see the point where you start to brake and how hard. Usually should be very little time from the point you let go of the gas to the point where you start to brake.

Also you an compare the gears you use to the fast lap log. Take into consideration different gearing if you have the log from someone else's bike.

This is the main screen I use at the moment. But would love to hear from others as well, especially on suspension travel.

One channel that can help is the delta. It is a way to see where you gain and loose in comparison with another lap (pic from the AIM Race Studio). The delta and the speed channels are The most important channels to watch. I believe there is a delta channel also in the BMW datalogger...

We have only a TimeDiff channel and since we can't create any channels in the Kit version that's all we can see here.

Andy, I for one, have the front sensor from 2d. I have tried to check the front suspension travel, also the rear, but it's mostly gibberish for me. Can you please explain a bit on a screenshot how it should work or what to look for in a fine tuned suspension?

The link I published earlier has some info about suspension potentiometers that can help you start understanding...

Totally agree - figure out, what the 2D software offers you for templates for suspension and read the theory about it.

But honestly I can't tell you just from the data if your rebound or compression is too hard/soft that easily and beside a detailed analysis is only possible if you can ride some decent laps on a track without crusing around. Check min/max suspnesion travel, speed and how you actually feel about it.

The data you are after are from years of expereince like how fast your front fork dive under braking, what's the avg position mid-corner, what's the fork position on the straigth - I don't have a guide for them.

If you have a chance to book BMW HP race days then invest the money and they can tell you more about the BMW, the HP Power Kit and data analysis.

I picked up one of the data loggers from California Superbike a few weeks ago at the Ridge for my new S1000. I was setting it up today and found it actually had stored off the data from my last run of the day on my initial ride which gave me an opportunity to play with the software.

Still some things I'm figuring out. One is that the 'wizard' did not get the turns quite right (probably more on my weird lines than the code) and I haven't found a way to manually map those out.

Will definitely have more to say once I've got a full day of data and can play with it some.

 

[bananaman]

Just received mine, headache already! How do you set a start/finish point?

 

[BMW_388]

@bananaman
To set the finish line:

once you have the session open in Anna Liza
right click in the view window and open "measure"

Now you have a RED dot that moves around the track view line, so, once you get to the location you want the START/FINISH, Click and the dot turns BLUE

now, right click again and click on "GPS" > SET GPS START LINE

Once that is open you get a box to save the name of the start finish line.. so give it a name click save
it will create the laps based on that Start Finish

Also download the full Analyzer docu from the 2D website - even we don't have the full functionality you can read what you need to know
