I love drifting but I hate how subjective it is. I do enjoy some of the subjectivity but things like “did he straighten out” or “was he off clip” should be easily and definitively answerable. I also love data. I have a G27 steering wheel and play GT6 drift modes trying to best my scores over and over again. And I want that in my car. Hopefully I can do it for less than $200.

As a result, I’ve ordered this obd2 arduino logger. It comes with an OBD2 interface that will log to an external SD card along with gps/accelerometer data. Eventually, I hope to put in an expansion IO board to capture external sensors like the hydraulic hand brake, regular brake (percentage), and clutch. Newer obd2 cars have steering wheel sensors but I might have to retrofit one on my car. I’d also like to get a second accelerometer to derive slip angle during runs.

The hope is to create a screen that will display basic diagnostic data in real time (temperatures/pressures/CEL codes) and also sense drifts to score them like most video games. Finish a run, get a score, gloat to your friends.

Goals:

Score/log drifts and drift telemetry

Map out courses on tracks via google maps and the gps

General data logging to SD card

Data logger analyzer

CEL read outs and ability to clear codes

Gauge readouts in real time

Flashing yellow and red “Danger to manifold” screen

No frills always on capability (start up the car and it logs)

Once I get the board, the first steps will be showing basic gauges and logging OBD2 data to the SD card. From there, I’ll move onto other inputs and extras.
