- that's a Vacuum Tube Volt Meter. I used this for the analog output of the needle swing, vs the DVM (digital volt meter) that is hard to read with rapidly changing voltages. I also wanted to see how the different types of 02 sensors (T vs Z) would work or not work with the 1988 300zxt ECU.
note the ECU was set to MODE 1 which is ONLY the green light. I should have had it set to MODE 2 which would have shown the red light flashing with the green showing closed loop function.
