The innovate LM-2 comes the most recommended but it has a lot of extra features that fulfill no function on my 1969 mustang (OBD connection, by way of example) and which add cost. All I want is a dual sensor wideband so I can tune my car perfectly and keep it that way. FAST makes a dual sensor wideband and it is about $140 less than the LM-2. I am very close to making a decision. Do any of y'alls have any informed opinions on the matter?
