    I love the new design and features! I mounted it next to the tach with no mounting cup needed, just made a simple mounting bracket.

    You need this if your serious about performance. My laptop with software was hypothetically at a good afr at WOT..My car felt great.. After installing this in my 1994 Z28 A4 car I test drove amd saw I was off a full point lean at WOT. I made the corrections needed in my VE table and you can only imagine the difference in power. IF YOU ARE OBD1 LT1 FBODY YOU NEED THIS SENSOR! EASY INSTALL ! Just remove cigarette lighter and grind the whole big enough to clear the 2 plugs and stud mounts!!!
