This morning I was tring to get my digital tach to come on. But some how r another I turned on CAI comes on odo how do I gett this off and what's it mean I posted this off my phone srry for the errors.

 

What happens if you turn the key off and back on?

 

CAL or CAI?
could be your compass maybe?

 

A little confussed, i see digital tach, making me think you are talking about a programmer like CTS/Gryphon/Edge, etc. Did you set the display to something you were not trying to display? If you get a chance please clarify.

 

CAL is the compass, follow the instructions in the owner's manual for completing the calibration.
