I know tbit=8xtq and brp 11.

The problem is where I edit this values ?

I'm using #import can-18xxx8.h

You can redefine the CAN_BRG_xxx constants in your code prior to including can-18xxx8.h. The new values then take precendence over the default values. But please don't ask me about the appropriate values, cause I'm not familiar to CAN. I guess you find them in the device user manuals.
