What is your geometry? It is very important that you have the correct bracket geometry where the cable attaches to your injection. Other than that the Lokar cable adjusts just like any other. Open your throttle all the way pull the cable out all the way and adjust the cable until it matches the WOT position. Then close the throttle and see if the unextended cable position matches the closed throttle position. Some pre-load on the cable is desired at idle position.
