Odd data logging problem

[BAC5.2]

I tried to see what this AP datalogging thing was, and noticed an odd issue.

 

I went to the "log data" screen, pushed OK, then hit the button again to start logging. It logged for a whole 3.18-seconds, then stopped. The time resolution of the scan was TERRIBLE as well, only 6 data points.

 

Am I doing something wrong?

 

I also did a "dyno" run. 3rd gear, 2000 to 6300. It quoted 297whp and 325ft.lbs of torque. Clearly not right for a stage-1 car.
