I'm looking into getting a uprev tune on my 2003 g35 sedan with new ecu. I was reading that you need to install wide band o2 sensors to get the afr. I see innovative products sells them for my car but idk what to buy. I see the sell a gauge with whole set up also sell a afr recorder do I need the recorder to use uprev or do I just need to install the o2 and gauge. I'm alittle confused on the subject new to the g35s. The gauge and o2 is like 300 where the digital recorder and o2 is like 700. Thankyou for your time any links to help me to understand exactly what I need would be appropriated. Just want basic tune not racing on track.
