I was having major issues with autoplunge hitting the upper flipper. I tested last night and got 1 out of 10 around the loop. I've done a lot of tweaking with pitch and autoplunge strength and really didn't have any luck. I also tried using the shooter lane adjustment screw to push the end of the shooter lane as high as I could get it. Still no luck. Today I took some advice from the Iron Maiden owner's thread and did 2 things. I very slightly bent the left shooter lane guide toward the center. I changed coil setting to "hard". Now I'm up to about 90% success with no further changes. I'm hoping it stays that way, at least for a little while.
