Hey guys, so i dont want to sound dumb here but i am a little confused. Im trying to set up my lc1 to log into link v3, i want it to work as a wideband and not just a narrowband sim. It is going to be in the front o2 however i can put it on the downpipe, but i will need something to plug the hole on the o2 housing. Also firstly i cannot get my lc1 to even do the initial calibration, the led indicator just blinks twice over and over, and the gauge reads 7.4. I have read that sometimes they may be set as lamba from the factory. So to try and hook it up to the logworks program it comes with and reset it to wideband. However i cant find the analog IN. Sorry for the book, any help appreciated, thanks.
 
Its brand new, although it may be possible i really hope not :/
 
7.4 lambda is like 108.8 afr, which is infinitely lean...I doubt it's set for lambda, I could be wrong though. I'm betting it just needs to be calibrated correctly or set up in LMProgrammer (assuming the sensor is not damaged).

Sensor Calibration:
4. Do not connect the O2 sensor to the LC-1 or in to the exhaust yet.

5. Switch 12V supply to the LC-1 ON and wait for 20 seconds. The LED will flash a two blink sequence during this time.
6. Switch the 12V supply OFF after 20 seconds.

7. Connect the sensor to the LC-1's sensor interface connector but do not put the sensor in the exhaust. The sensor must be exposed to free air for the first time calibration.

8. Switch the 12V supply to the LC-1 ON. The LED will first blink slowly and steadily indicating that the sensor is warming up. The LED will then start a faster blinking sequence indicating a Heater calibration.
9. Once the LED is lit steadily, press and hold the push button for 30 seconds. During this period the LED will go off. Once the button is released the LED light will come back on The LC-1 will now
calibrate itself by using air as a reference gas with known oxygen content. After the free air calibration is finished the LED should light up steady and continuously, indicating correct operation of the LC-1.
10. Install the O2 sensor in the exhaust. The system is ready for use.

It sounds like you're stuck in this state, where the sensor is not connected to the LC1 controller. You sure it's plugged in all the way?

You have an error no. 2:
Heater circuit open
Cause: Damaged sensor cable or Cable connector not fully seated
Solution: Verify Sensor connector is fully seated into unit. Repair/replace Sensor or cable.

Got it solved, i hooked up the analog to the program it comes with and reset it, i was getting the heater errir. It then proceeded to do its thing and all is well, thanks for the help guys.
