you can run it in closed loop you just change the closed loop voltage to something around 2.3 volts then the ecu tries to maintain that voltage which is about 14.7:1 instead of the .5 volts on the narrow band 02. You are probably better off running in closed loop off your stock o2 but you can run ...

Just follow the same instructions as the plx and then change the values of the o2 in the s300 to read 0-5 volts. Thats how mine is set up. you may have to mess with the voltage correction so that your s300 and you wideband are show the same numbers and reads right. It's really easy and works fine ...
