well im going to be getting a wideband and im look at the innovative on ebay for $200. my car is a 99 civic ex and im getting my p28 ecu in a few days. so i need to make a datalogging port which shouldnt be to hard. but the wideband is still confusing me. does the p28 ecu only work on one sensor or both of mine cuz my car has one before the cat and on the cat? so if i were to get the innovative does it plug in the o2sensor harness before the cat or do i have to cut the wires right after the stock narrowband sensor and wire it up to the wideband sensor or do i have to make a new wiring thing to the ecu? and what does calibrate mean? they say in the video on innovative they calibrate it and ---- that has me confused. if i dont have one of those box things how do i calibrate?

i also have a 99ex that had two O2 sensors. once you go obd1 with the chipped ecu the secondary o2 is just there and doesn't do anything. at least it doesn't seem like it. i gutted my cat and just left the sensor in it just to plug the whole and don't get any codes. i have the innovate LC-1 wideband and when i got it i had to do a little wireing. nothign hard just twisting wires together and i put some male connectors at the end and used a T tap for the power wire on the ecu and ground. then find the o2 wire on the ecu and clip it and put a male and female connector on it so that when your running normal you can just plug it in, but when you want to use the WB you just unplug and plug in the wb.


i really hope that makes some sort of sence

do you know where i can find a wiring diagram my car has 4 wires on the downpipe sensor can i cut these and hook it up to the wideband? then do i just go in uberdata and put in the wideband or do i have to chip anything else? can i run a wideband all the time instead of a narrow.

you really don't need to hook up the wideband for full time use. i just hook mine up for tuning then put the stock one in after i'm done.
