help with MEMSIC 2125

I am having some problems with my memsic 2125 accelerometer. It works and displays an output to the LCD I am using. The numbers are WAY off though, how do i fix this? I have tried a software calibration but the application i am using this for needs it to be fairly accurate. The value from the accelerometer keeps bouncing and never stays at a steady state. Any suggestions?

The numbers are WAY off though

Without knowing what numbers you're displaying or how you're scaling, we can have no idea what "WAY off" means.
Can you post some code, and maybe some examples of results?

I'm fiddling around with my Memsic 2125, and it doesn't seem to be working... could you post a picture of how you've got it wired, and the code you're using in Processing?
