I've been looking at motorsport dash devices and I'm wondering if anyone here uses one. There are expensive full dash units with screens and shift lights, lap timers and track mapping; mid-range modules for sending data via bluetooth to an Android, and then less expensive units that use the GPS/Gyroscope from iPhone/Android.
Some of the features seem redundant to what is already available on the dash (
oil pressure and temp, tach, speed, et cetera...), except for GPS/Track-mapping and then the data logging.
Anyone have experience with these? Any opinions?
