adjusting the km/s - gas gauge problem
 

hey whats up

i have a 98 civic si
the gas gauge is always going to full after 10-15 min of driving, then comes back to normal then back to full.
anyone else heard or had this problem b4?

i changed the sending unit, no difference.
so i got a used cluster. but the kms are only 74 540. my original kms are 275 000.
anyone know how to adjust the kms?

thanks for any help
