Just a thought..... I phoned a friend :P and he put in a suggestion that the LC-1 and/or the O2 sensor, may be very susceptible/sensitive to "overheating"

The O2 sensor itself is mounted on the number 3 exhaust tube, approx 9 inches from the exhaust port, as I have Apexi extractors. In other words the sensor is mounted alot closer to the engine than the stock location.

Could heating be an issue?
Could this be the reason why the LC-1 kits come with a strange-looking heat-sink?

I doubt it. I ran mine in the stock location for a few months more after I solved all the problems and it was fine.

If I was in your shoes, id troubleshoot the obvious first. Change the power source.

It's not the grammatical errors that prompted my response. They were merely an (ironic) bonus.

dug up the Innovate manual, and it states that the sensor can give incorrect readings and even fail if working in temperatures over 900deg F.
The "funny looking heat sink" I mentioned is a actually a plug and a bung so if you have overheating issues, the instructions state to plug up the original hole and move the O2 sensor further downstream.

This would explain why I get the funny readings after an energetic mountain run, and on the track.

You are bad friggin luck.

I went for a drive on saturday and my LC1 started doing exactly this.
After 1 year of trouble free driving, you had to jinx me by bringing this thread back from the dead.


Basically, it lost its free air calibration. I recalibrated while driving, so its all good, but was pretty pissed until I figured it out.

Anyway, check to make sure your calibration button isn't shorting out, it may be screwing up the free air calibration. Also make sure the sensor is plugged into the controller completely, if the controller loses the sensor even for a moment it forgets the free air calibration.

If it was overheating the light would blink you the code, E8 I believe. If it does not then its not overheating.

sorry to see the LC-1 is so temperamental. i could say **** the AEM UEGO 40 times in a row and mine will still work tomorrow morning when i start the car.

proof:
**** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO **** the AEM UEGO

OK, that's only 39, I got nervous that maybe the WBO2 gods will smite me.

My LC-1 always works. It has no conscious. No feelings. It never complains. It just does what it's born to do.

And is it true that UEGO is pronounced "way-go" as if it's one word? Waygo?

I think the LC-1 is temper mental to proper installs and perhaps the random weirdness problems are actually caused by a dirty power supply feeding it. IE, noise. I installed mine per the directions included with it and it works fine.

Sam, you should share with others your new found method of recalibrating the LC-1 if it's not already discussed here.

Now youre just making fun of me.

I also didn't "find" the method. I read about it on the LC1 forum a year ago while going through all my issues. I didnt believe it would work then so I never tried. I had nothing to lose this time around so I gave it a shot.


Got on the highway, fourth gear going about 80. Went into a coast, waited for over-run, counted to 5(slowly) and hit the calibration button.

I have yet to take a log and use it against my current table, but from my own knowledge of the readings the LC1 gives me while I drive and most importantly at idle, its spot on.

Not making fun of you at all. I think it's much better than having to jack the car up and pull the sensor. I just wish I knew about it earlier. Would have gotten far fewer screaming calls from a friend every time he had to recalibrate.

Hey... I'm a sharing kinda guy

Thanks for stating the free-air calibration method WITHOUT taking the 02 out of the exhaust. Where the 02 bung sits, it ain't the easiest of things to get a spanner on.

I'll try it out.

Just wanted to say thanks for this thread. I'll be receiving my LC-1 today and hopefully have it installed over the weekend.
