In Lemons, keeping an eye on your lap time isn't often that important.
As a team captain, I am normally more worried about the condition of the car, and that's something that the lap timer cant really tell you.
Real-time data logging is where its at and Race Capture has an awesome system for this.
basically, 1) buy their datalogger unit and plug a bunch of channels into it. Like temperature and pressure sensors, fuel level, etc.
2)buy an android tablet and mount it to your dash. The race capture now outputs all the data to the driver as gages
3)pop a 4G card into the race capture and now the guys in the pits can view that same data-both real time and historical.
The unit has built in GPS and accelerometers as well, so bonus, you get the lap time data as well. If you really want to judge the driver, you can later add throttle position sensors and brake pressure sensors.
I really want to put the race capture in our car. For $500 its a sweet setup.
