Also, just out of curriousity, i've never timed an engine that is ALL computer controlled, lol... How do i set the timing back when i goto start it up, or does the computer already know what to fire cuz of the Crank and cam shaft position sensors? I have not taken apart the timing gears or anything, decided to stay stock cam for alil while longer to save some money, but will be doing that in the near future... all i've done is turn the crank with the heads off to inspect the cylinder walls.
