Dl-1

[David Ferguson]

I'm sure the discussion was about the Race Technology DL-1, a GPS & Accelerometer based data acquisition system.

What sensors are useful with data acquisition systems depends on the questions you are trying to answer. You can measure vehicle and driver performance with the basic DL-1 without any additional sensors. But if you're trying to monitor your engine parameters, then having RPM, a temperature sensor and an oil pressure sensor might be useful. If you are looking at driver technique, then throttle position, steering, and maybe brake pressure would be helpful.

Beyond that, what do you want to know? Suspension position? IR-tire temps? Airbox pressure?
