Harry, thanks. That's what I wanted to hear. looking at the first good image from my pictures above, I can imagine a 5x improvement would make that picture a LOT more informative. W/a 1Hz data rate on both GPS and the Accelerometer, I don't really think you can gather any useful data about your driving from that. I want to see where my measured brake zone are, where I'm accelerating vs where my friend is braking and accelerating. Looking at my videos w/the Overlay, There is a noticible delay between the video and the acceleration circle. Through the slalom, the acceleration circle lags behind by about 1 cone. It's still neat to see. Will have to upgrade to the Dual XGPS 150.Harry wrote:Yes, the Dual will give you much better values here. On recalibration: usually LapTimer keeps a calibration achieved. There are certain situations however, things are reset. LapTimer runs a sanity check calibration is fine from time to time. If e.g. LapTimer detects zero speed, but a high acceleration (actually it should be zero), it will start over automatically.

Part of the course was rediculously rough for the car. I am wondering if that might have had something to do with the calibration getting out of wack.
