I eventually need an air/fuel gauge. I was planning on getting the knock sensor as well. Does anyone know if this is an accurate unit? Or do any of you guys know of a better one? The only thing that concerns me is that it looks a little like the auto meter. With the way it graphs itself, with little lights. I know for a fact the autometer one is crap. A friend has it or should say had it cause his car blew up. Was too hard to read. So any help would help out alot. Thanks

 

Im guessing nobody has it.
