Yes Theo that's correct. Ive left one of the analog outputs as is to mimmick the oem 02 sensor and programmed the other to suit me. As mentioned in an earlier post, be careful not to connect that second output without first reprogramming it's output voltages. From memory factory defaults were 0 to 5 volts and not sure how the ecu would react to a extra 4 odd volts. I programmed the second output with 1.2 volts as a maximum (to give a rich mixture) and .2 volts to give a lean mixture(from memory -I'd have to recheck my values). This actually reverses the graph from factory defualt but it seems to work. As i said there is still a bit of tweeking to do so hopefully I can get some input from yourself and Greg when your installs are complete. Good luck and hope it gets you good results .
Eddie.
