Was wondering what are the good packages and if they are worth getting. I'm trying to see what my 02' Liberty's engine/transmission is doing specificaly, but also would like it to be universal for other cars and be CAN compatible. I've seen the Auto Tap on the net and it looks interesting. The $200 price is about right, but according to their Chrysler Parameter Page, don't show gear/shift point/converter lockup that I would like to have. That is unless I'm missing something. Any information or any other products that you guys have used/recommend would be most appreciated. P.S. I a noob at this so easy to use/good technical info would be a big plus. And I already have a laptop.
