Well, the Trunk catapult shot WAS working perfectly for the previous 3 months but now it's all over the place. Coil was adjusted to 27 and it made it under testing load, but under game load the shot would fall short, so I adjusted it to 28. Now it will overshoot the trunk consistently. IF, however, you hold both flippers (attempting to draw voltage away from the coil), it makes the trunk shot beautifully, but it will still miss long if you don't hold the flippers as the catapult fires. Basically 27 is too weak and 28 is too strong.
The only major change was going from March code to May code. Is anyone else getting issues like this?
