Data Logging
 

Starting to look into getting a data logging system for AutoX purposes. Currently looking at the Race Keeper SE-10. Plan would be to use the OBDII adapter to capture throttle and steering angle (still need to see if steering angle is avail over OBDII) and probably just wire a digital brake input for the moment. Definitely like the integrated video capture with up to 4 cameras (Only 2 at a time).

Anybody have any experience/suggestions with logging systems that might work well in this application?

Steering Angle isn't available so far as I know.

Those systems are damned nice, I'm going to try and make do with various smartphone-based solutions for as long as I can...

I'm pretty sure DR_ uses the Race Keeper Black Edition and likes it. If he doesn't see this thread, you might search or PM him about it. I don't have any personal experience, sorry :tiphat:

I only use Harrys Lap Timer at this point. I had a DL1 back when I raced wheel to wheel but even then it wound up being used more of a advanced lap timer then for getting data that I could actually benifit from. Unless you have engineers looking over the data and mechanics to make adjustments I think there is very little benifit to be had.

I am an engineer, so the data would be a good thing.

My fault :tiphat:

It was wstar that uses the Race Keeper Black Edition :tup:

Regardless of what you buy, make sure you download the demo of the software to make sure you can use it. As DR said, you don't want too much data that you can't dissect it.

I have a racepak iq3 w obd2,

Aim MXL
;)

I love my Aim Solo. I don't think you have to be an engineer to use the data... try something different, note the lap and see how it affects exit speed, etc.

AIM's software is free to demo.

I use the AiM Solo DL which captures all the data you asked for, throttle position, brake pressure, steering angle, wheel speed sensors, RPM, as well as all the GPS data for lat/long G's, position, true speed etc.

You have to capture the video separately with this one, but the price is right. I use a GoPro for the video, but if you like it easy buy the AIM SmartyCam setup and connect them together.

Here's a sample of the video medley of the AiM Solo with GoPro video, rendered together with RaceRender.

I'll add that the AiM analysis software is quite powerful but a little tricky to learn. The basics are easy but I'm still finding new features all the time :tup:

+1
on the AiM SoLo DL ! :)
Ive been using it since the unit was released.
Best buy ever for the price and capabilities.

So to confirm, the AiM Solo DL will pickup steering angle and wheel speed sensors from OBDII on the 370Z?

dataloggers are pretty useless in autox

It does. I show the steering position in my videos. Wheel speed is also there in the data steam.

Not one for necro bumping threads but just thought I'd share what I ended up going with or more to the point, built/programmed. Current version only does GPS (position & speed) and 3 axis accelerometer data but with with a few more parts it'll be able to grab OBDII data also. This is only the "beta" version and I haven't had a chance to build a interface yet so it still looks rather rough but it does function. :tup:

Please ignore the dirty table it's sitting on.

We are using AEM AQ-1.

AQ-1 Data Logger

Will be collecting variety of inputs, throttle position, inline brake pressures, oil temps, gps data, built in accelerometer, all engine vitals, steering angle and more.

Planning to do bit of a write up on data logging once we have car on track and start using this unit.

For autocross = solostorm

/thread.

Good info I was researching data logging too recently.
I found with a little effort on my part I can just use my phone/w app, ODB-II reader , and some software to put together a video (from my gopro) with all the relevant info I would need.

As much as having obd2, steering angle, throttle etc in your data, I'd guess 99% of people will not even use it, so a regular cheaper lap timer and datalogger is more than enough. For example:

Aim Solo DL (no obd2) about $399 I believe: AiM Sports - The World Leader in Data Acquisition
software is a bit hard to get used too at the beginning, lcd is monocrome only, predictable works well.
Qstarz LT-Q6000 will do the same as above retails same $399 LT-Q6000

The Qstarz can be had for way under msrp, vs the aim solo you are buying at MSRP.
Cons: no odb2 support
Pros: color lcd, green=faster, red=slower, predictable works well also easier to use software

Racekap G2x: tons of people run this one, very easy to see your lap times and segment if you are going faster or slower
cons: pricey but this can be found use for very good prices

Racepak Iq3 datalooger/dash: works very well but damn expensive, this is what I run on my car along with a Qstarz lap timer.
has obd2 support ($$ for cable), and you can add any sensor you want to it ($$$), everything is programmable and has shift lights as well.

Qstarz is one of my sponsors so if anyone wants a good deal I can hook you up with the Qstarz rep.

I found working with the racepak data is pretty damn complex so I don't do much analysis with it.

I found this on AIM site detailing datalog functions available for 370Zs.
