I've read about it, and from what I understand it has a 10hz GPS unit in it along with accelerometers and OBD II interface. I'm trying to achieve the same thing with my phone but I need to get an external 10hz GPS unit (for position) and a better mounting solution (to have good accelerometer data), and I already have the OBD II data logging. As far as display goes, I have a head unit in my car that mirrors my phone. Essentially I am trying to get the data acquisition with a clean integration into the car. So far it is a work in progress though I am getting better with each event.

The problem with the data I had from my spin was that the accelerometer data was bad from the mount having too much play and the GPS was nearly useless except for general lap times (no decent correlation with exact on track position).

Hahaha that sounds kinda complicated, AIM makes it simpler but that comes with a price.... Ya usually spinning out turns off lots of sensor even GoPro too iono why

We use an AIM Solo DL in the CSG BRZ, and I use one when I'm doing instruction.

Let us know if you're interested!

Save yourself the headache and just get dedicated unit. While the phone apps will give you accurate lap times, data acquisition is unreliable. The root of the issue is that the external gps and obd2 units are WIRELESS. You will constantly get dropouts and disconnects. Been there, done that...

you got really lucky!

Thanks to all who posted in this thread. This has been super helpful just reading. To the OP Glad your okay and your car is as well

Whew, DAT DUST STORM!

Glad you and the car came out ok.

I dropped two wheels at Turn 2 Grattan raceway (MI) last year and it took all my willpower to not yank the steering wheel the other way.

Lots of good preventive advice in this thread for a beginner like me.
