When you say the auto-reclose isn't working, does it not attempt to pull down the hood after 90 seconds, or does it try to close but the factory latch misses grabbing the hood striker since it's sitting up too high?
Maybe I just got lucky and the auto-close function is working well on mine without the patch which I think is supposed to help with the auto-close. I also have the plastic alignment insert on my version, but it's only on one of the bolt holes so there is a little bit of adjustment you can make by rotating it which can change very slightly where the striker pushes on the trigger bar. Also, with the heat shrink tubing I added around the "arm" of the soft-close trigger that bar is now slightly thicker and may help with maintaining contact.
It sits very high up, as if you gently lowered the frunk down to where the latch was resting on the sensor arm. That registers as fully open so it does not try to re-close the frunk. Good point on the rotation, that'll be the first adjustment I try.
