So my dealer here offered me the info gauge by Greddy. It cost about as much after customs as the AFR gauge from gtm. The info gauge connects directly to the OBD and you have the ability to connect to the info gauge external sensors as well. A couple questions: 1. What can be checked through the OBD? 2. AFR, oil pressure, AT temp, etc. 3. If so are these readings accurate? 4. Does the car have a wide band?
thanks
