Control valve lapping is a controversial repair method, not recommended by OEM’s. One of the main reasons is the compensation calculation after the lapping may become very complex and the repair of the injector with the lapped control valve may become almost impossible. Maktest KO4000 Cars system practically recalculates all the critical dimensions after the lapping very successfully and eliminates the risk of failing during the Flow Test.
