WriteInstinct Calibration Issue

I'm getting some weird values for the acelY when I use the WriteInstinct Calibration. Any Suggestions on what to do about this? I've tried it about 3 times now, and the number is always -32768. Data is printed as: acelX acelY acelZ giroX giroY giroZ

Readings should be close to: 0 0 16384 0 0 0

Sensor readings with offsets: 6, -32768, 16375, 0, -1, 2,

Your calibration offsets: 1718, -4096, 1031, 73, 17, 46,

The offsets are saved and automatically sent to mpu.setXAccelOffset(yourOffset)

EDIT: I'm using the Bittle kit, and have the NyBoard V1_0
