what is the best way to hook up WB02 signal?
hi, i just got a Innovate LC-1 for my FD, there are 2 programmable signals output, i have a Datalogic box, a AFR guage that is tapped to my factory narrow band O2 signal wire on the PFC harness, PFC commander and a Blitz I-color that can take any AUX input with programmable range. so wat i have in mind is:
cut the wire from the factory narrow band O2 sensor to the PFC, and connect one WB signal to the ECU side that's programmed to 0-1v, so both my A/F guage and PFC will get a WB signal,
and hook up the 2nd WB signal wire to one of the AUX input of the datalogic, so i can log and tune. i do not know exactly how to since i lost the manual of the datalogic, i assume just put that signal wire to one of the screws, and i wanna have hook up my blitz i-color to that same spot.
question is, is there any need for the PFC to see a WB signal? since there isn't any autotune features, and O2 cant be monitored in the commander, also i guess most people have the O2 feedback option unselected.
and if i split the signals to 2-3 devices, will it become not accurate?

your narrowband gauge is completely useless. The only thing it tells you on a practical level is whether you are in closed loop or not. If you are running a PFC you need to turn o2 feedback off (resulting in no closed loop) unless you have a functioning cat and airpump. So toss the narrowband gauge in the garbage and get either the digital XD-16 AFR gauge (which also has a calibration function so you don't have to have a switch wired up) or the cheaper analog one they sell. Cut the narrowband signal out altogether.
you can tap your blitz into the 5 volt signal from the LC-1 but I would make sure all the grounds for the blitz run to the same main ground (not the heater ground) as the LC-1. this signal is very sensitive to electrical noise.
for the rest of the stuff, you need to do a search. this has been covered extensively. I even made a thread about wiring it up: https://www.rx7club.com/power-fc-forum-47/my-power-fc-lc-1-xd-16-datalogit-wiring-diagram-707298/ . read the links at the bottom of the thread as well, including the innovate tutorial.

thz for the info, i know the o2 feedback for the PFC only adjusts the mixture when idling or curising, so no point hooking up a wideband into that since it desn't selftune like AEM or Emanage. i ended up hooking up a 1-5v wideband signal to the AN1 of datalogic and shared with he Blitz i-color Aux input (which is preset for wideband 1-5v), and hooked up and other 0-1v signal simulated 9-16 A/F% to my narrowband A/F guage, becus it's easier for me to read the guage than the jumping digits.
there is a setting for response time for the LC1 wideband output: instant, 1/12sec, 1/6sec and 1/3sec, which one would u guys use?
