need help with lc-1 wideband

[Mustangless]

I can't get this thing to work right. I have it hooked up, and calibrated. Under logworks it gives me like 20.9 for a while, then it will go down to like 4.x then back stuck at 20.9 for a few seconds. Under tweecer if I select innovative it will be like 24.xx or 40.xx

Does anyone have any tips for me?

I had that same problem when I first put mine on - the readings were ALL OVER the board.

I had to recalibrate it in open air and it started working correctly.

Double check your grounds and all your splices.

It's well worth the effort once you get it going right!

My Notes from my LC-1 install

I got a question about free air calibration

It says
1. to connect to 12v and turn on (turn key on)
2. push calibration button after sensor warmed up for brief period (5 seconds?)
3. after calibration is complete switch off for 30 seconds before starting.

Is all of this done while in the exhaust, or do you take it out?

What you want to do is pull the sensor out the exhaust and let it hang in open air when you calibrate.

Put 12v on the sensor and let it warm up. If you have a status light, the light should be solid green and not flashing. It takes my sensor 20-30 seconds to warm up.

At that point you can hit the calibration button. Your status light will go off for 2-3 seconds and then go back to solid green.

You can then shut the 12v off and put the sensor back into the exhaust.

The calibration only needs to be done every six months are so according to the documentation I have.

It is possible to let the car sit overnight and then calibrate the sensor in the exhaust pipe. This allows all the exhaust gasses to hopefully escape so that you have "open air" in the exhaust as well. Since calibration is done so infrequently and because I need my AFR to be as accurate as possible, I calibrated it in open air - well worth the 10min or so it takes to unscrew it and screw it back in.

if I have one narrowband, but both are wired to the one, do I need number of hego sensors to still be 2?

Spend some time checking your wires and grounds, its well worth it. The innovate forums are also helpful. Stanger007 i used your wiring scheme and it worked flawlessly. I ran both sensors to the locations you told me about. The only issue i had was i needed to replace the heater ground bolt with one with a nut on the back to hold it tight becuase i was losing heater ground. I now have both widebands up and running and have replaced the factory o2 sensors with the widebands with no issues. I havnt tried disconnecting the factory sensors from the heater circuit but i did clip their voltage outputs. I found that my car is running 14:5-15:1 at WOT, yikes!

I wouldn't run a wideband and a single narrowband - keep both the factory sensors and add the wideband or replace both factory sensors with two identical widebands like Vyal did.

Glad to hear ya got it going Vyal!
