The Maximum # of honors points is 8 semesters or 4 year long classes for the capped weighted, not 8 Honors classes.
Are you on semester grades (2)/year or 1 grade per year?
I get 4.25 Capped weighted and 4.58 Fully weighted. Regardless you are a competitive applicant and but not a shoo in for UCLA or UCB.
UCI is definitely a Match/Target school.
Best of luck.
