I have dynojet Wideband commander that I have been using for a few years and love it. Now I was just messing around and I stumbled on Innovative's website's forum. On there was post regarding how there Widebands are much more accurate because the offer "free air calibration" while sensors such as the AEM, PLX and Dynojet do not. Is this true-so I could be getting false readings all along? I need a pretty accurate reading since my car is FI. What are your thoughts opinions? Thanks!
