WB Swap

[Yamahaulin]

Ok let me give you a run down on what has taken place. The car had a Inovate LC-1 o2 sensor on the car when i bought it, the owner couldn't tell me how to get a reading from it, so I decided to install a new Autometer Nexus WB and gauge so that i could see what was going on. Well in the process of the uninstall/install i noticed that the LC-1 was hooked to the 02 wires on the ECU, by the time i had found this out I was about 80% uninstalled so I went ahead and finished taking it off. I installed my new WB and guage which works great, nexus rocks. Anyhow now my problem is that I don't have any 02 readings going to the ecu, I guess the LC-1 has a NB capability on it. He cut the factory wires at the ecu and hooked the wires in from the LC-1. My question is what should I do, the car runs great even in open loop, which should be because i have no 02 reading right? What should I do here, i'm kinda stuck. The AFR's are great cruising, idling and since closed loop doesn't effect wot it's good too. What would the disadvantages be to leaving the car like this? Also why isn't my service engine light not on when i have no 02 readings, is that something to do with link?

Only one way to know...post a log idling and cruising showing CombinedFT. You can also log the open loop variable that specifically tells you if you're in open loop mode or not (there's a corresponding closed loop variable too).

I can't even find CombinedFT to log it, it's not a value I see. I believe it shows a 1 next to the openloop status as i found where i could log that. Just going off my AFR's from new wideband everything looks good, i'm going to try and get it hooked into the ecu so i can log it. Why can't i find CombinedFT where would it be, i'm going back out now to try and see if i just overlooked it.

Unless your calling CombinedFT both of my LTFT. That's the only thing i could see. The more i'm driving the more holes I see in the tune running SD, guess i'm gonna have to reinstall this damn LC-1.
