Track data recording
 

Is there a better app out there for Android besides Torque pro for datalogging basic OBD-II data? The autocross sessions here are pretty short and probably don't need to record data, but I would like to try to dip my toe into data collection before I get to actual track time and better data systems.

I use racechrono, but primarily for timing. It can log a good amount of OBD data too.

I'll take a look at it. Thanks!

There's not really a middle ground, you either spend <$100 and it's a little janky or you jump up to >$200 to SoloStorm or AIM.

Lots to be gained in getting autox data if you want to be competitive there, SoloStorm is great.

I tried a lot of free apps and couldn’t find one that did what I wanted and went to SoloStorm and it’s awesome and also works on track.

Then once I got used to it and wanted even more data I paired the solostorm with a RaceCapture and it’s amazing.

Honestly, I am happier with Racechrono, an XGPS160 and MX+ OBD link then with my Aim. The aim has some nice features but it's buggy sometimes. I get pretty good data from racechrono. And the battery in my Solo2 died not even two years old. It was always a bit dodgy and never held a charge well even when new.

TrackAddict works quite well considering it's free.
Just pair with the proper blutooth ODBII module and an external GPS.

Just curious. What do you log with your OBD2 module and TrackAddict?

Thanks.

I like Trackaddict for the track (as far as free stuff goes), paired with a Qstarz or XGPS160 it is just as accurate as my transponder. That's what I use on my TT4 BMW for time attack.

For autocross, Solostorm for sure, with same GPS.

Add on a Bluetooth OBDII adapter if you want the extra info.

Solostorm for AutoX.

AIM Solo 2 DL for anything else.

I use an ODBlink MX+ and mainly use it for RPM and throttle position. Sometimes gear position as well.
G-force readings from the phone.
Position and speed from the external gps. A Garmin Glo 2
GoPro Hero 5 black for video with an external mic mounted to the rear license plate frame.
Data and video put together with RaceRender 3 (also free)

Here is an example of it all put together.

Is there a real benefit of an external GPS? I would have guessed the phone's internal GPS would be fine. Or does the external GPS offer faster refresh rate than 1 Hz?

The external GPS that solostorm suggests is 10Hz refresh.

I used my phone's internal gps for a bit, then switched to an external. The phone GPS was WAY off. Speeds were wrong and lines were wrong. They don't update nearly fast enough or accurate enough. I could easily see each individual point of data collection on Trackaddict. There were large gaps between data points, made the line all angular and incorrect.
