Are you sure that you mean "basal"? The basal is the injection usually the first thing in the morning or the last thing at night or both. The "bolus" is the insulin injection used to offset the carbs after each meal. If that is the case, do a tag search for "Advanced Carb Counting", but first have a look at "Carb Counting 101".
Check this thread for
basal level calculations and
this one at the end for the carb info.
I hope the info helps!
