Which transmission does it have? You need the C56 transmission .

If I am correct the VitzRS is the NCP91 and it should have the close ratio transmission. It should not bog down at 5k.. it should bounce the rev limiter at 190kmh on fifth gear at 6500rpm.

You should verify if it is an original RS NCP91-AHMVK

Verify the compression on all 4 cylinderes 213psi max, 156 psi low and max difference pere cylinder 14psi.

If your compression is ok procced to the regular maintenace items!

If not propably the piston rings are stuck. ( pm me )

Do an engine flush and use 0w-30 PFE ( diesel spec :) ) Cleans gunk out and can take 17:1 compression on its oil film.

Check intake for restriction and clean out the MAF sensor on the airbox.

Do the ECU reset you mentioned

Good luck !
