Me Too ,Meeeee Too..... I just did the same thing on my JKU X , I measured the tires, did the math and adjusted the dip switches , turned the ign. on, plugged it the ProCal and the horn honked. I smiled a big smile, proud of myself.... I unplugged the Procal shut off the ign switch, got, shut the door.
Went to get back in to move the Jeep out of the shop and the Door was locked, luckly I had the keys, got back in, tried to start and NOTHIN....just clicks, all the lights light up on the dash.
I wrote down a post from here about resetting the Computer, so I came in to get it, and read this post.
Sure hope somebody is there on Saturdays.... LOL
Good luck on yours Vampire !!...... BH
