Thread: Is data acquisition possible with just plug and play?

Yes.

You will want front and rear wheel speeds and lean angle too though.

With some of the bikes with traction control they may already have them...but can all that data be tapped into from one port is my real question.

The specs show it already has a built in accelerometer, and it's set up for a 0-5v input for throttle position. Should be plug and play - the bikes I have hooked up my PLX datalogger to have all been 0-5V TPS.

Different ballgame entirely due to total lack of electronics but I was thinking today how much I'd really love to have some sort of data acquisition on the motard. Lean angle sensor was at the top of the list.



I already have traction control installed for it. I wired one bicycle computer to the front wheel and one to the rear wheel. I just watch both at the same time. Anytime that the rear wheel speed is higher than the front I just dial back on the throttle...or return the front wheel to the ground.


In all seriousness I think that in the future I'll try to find something for it for data acquisition.

"Data aquisition" is trick and all that...but having a reason to collect the data you are collecting, and then knowing how to use it, are the real tricks.

I had an extensive system on the 929. Long story short, my conclusion was you needed a crew to really use it properly.

The newer stuff is much more user friendly in ultimate track mapping and all that and maybe I'd change my mind if I tried one...but getting the basics, wheel speeds and positions, throttle position, engine speed, lean angle etc maybe isn't as useful as you think.

Not really thinking of usefullness...but it would be nice to get a better understanding of whats going on and what the bike is doing compared to what I think its doing.

I definitely have no real reason to getting the data other than I'd like to see it. If I was doing more track riding though I'd really like a system that would at least show my speed at various points on the track. Something like this. They claim it is accurate enough to tell the difference between the inside and outside of the track so you can see you're actual line. Being able to see your actual line paired with lap times and speed in the corner would really help you to see if what you are imagining to be the "faster" way through the corner actually is. After that I'd like to overlay that with TPS and lean angle to see if I actually am getting to WOT when I think I am (I'd bet not in some cases).

I think for the majority of us it will just tell us to stop being pussies and open the throttle.

Well in that case Philly fans have no hope...

Looks very good. That seems to be what the other one I posted claims to do as well. I can't find a price on the one you posted? I really think that stuff could prove useful to even a semi-beginner for figuring out the fastest way around a track however at this point just learning to be smooth and get all my shifts in at the appropriate times would be more important.

Edit: looks like $859 for the DL1, the G2X is $699 or $943 with on board dash, with the DL1 you have to pay extra for that. Someone smarter than me would have to make an actual comparison of the internal tech. I can't seem to find the sample rate of the GPS.

I got to see it in action at the track with a pair of endurance team drivers. They were definitely able to overlay data and adopt each other's "fast sections" turning it into quantifiable results within a session or two...

Not enough details yet but this looks promising Solid State Digital Video Recording Systems and Cameras | ChaseCam And with that big Doc money you can get video and data sync. Could use a 3d gyro though

Sheep you dont like to read do you...look at the link in the first post...

the worst part is I looked part way but missed it despite that since I was heading out the door,

Wished I'd saved some of my data traces.

You will learn some interesting things, might catch some interesting events in the data (tankslappers look like the world is ending), but for the two years I used it as an amateur racer, I thought it was a waste of money and time. I already knew the things I needed to do to go faster, and it was very distracting to have to mess with in the pits. When you're running trackdays, or especially races solo, things are already tough enough without making them more complicated.

We put my system on a friend's bike for an AMA practice. That was more useful as we could take suspension rates to the Ohlins truck, among other interesting things....
