Doug, I welded bungs in my ERA FIA, approx 12 inches after the collectors. I use a hand held meter by FAST. I screw the sensors in only when I am doing tuning. Run the wire up the shifter hole, have to be creative for a power source, do not have cigarette lighter. A/F meter is great tool for tuning carbs, I will never do it any other way.
