I have a dual O2 sensor LM-2. I have also connected a TPS to my Quickfuel carb and Installed a GM map sensor. Both the TPS and map sensor are connected to the LM-2. The LM-2 can display on its screen or connect to laptop for custom display through log works software. The LM-2 will also log to SD memory card so you can review later. The logs include both O2 sensor output, engine rpm , TPS and map sensor output.
