well i woke up this morning and it was cool out for the first time in ages, and when i say cool, im not talking about a whole lot here as im in florida. i fire up my truck and the wide band worked for a bit then just dipped down to 7.4 and its just pretty much stuck there, got the truck to operating temp, put the hammer down and got some hot egts going to heat it all up, nothing. itl read a little something on the decel if i get into it hard, but for a second only, then its right back to 7.4. i don't understand it? i put a brand new 02 senser in, moved the bung back and added an extendo bung, and the lc-1 is only a few months old. it was all working 100% flawlessly ever since the extendo bung and new 02 untill this morning.
what do you guys think? bad ground maybe, defective lc-1? i dont know why this thing gives me so much trouble.

as i understand it. the lc1 should error out before it gives you a wrong a/f. so maybe the cal was lost.
some kinda spike on start up messing with the cal?
anyways, i'm in fl too. this little cold snap has been much needed. but back to 90s in the next few days.
yea i was pretty happy to wake up to a cool morning and not be soaked to my underwear in sweat by 10:00. and no, it never threw an error code, which really surprised me, it just sat there at 7.4. i let it sit and started it up after about 20 minutes and it worked perfect again. im just about to head out there and start it up this morning to see if its going to do the same thing.
There is a process to restart the process much like a new install. It involves disconnecting the LM1 from the sensor at the connection. My connection was handy at distributor maybe not handy for you. See owners manual. That may help or may not.
Do not turn controller on till engine starts and do so immediately when engine starts. I had all sorts of isssues with mine till I found the sweet sport then all was well.

the controller is on with key power, it shuts off when i crank and starts back up once the motor starts. i think i know the procedure your talkign about, i performed it a million times today, not on the one in my truck tho. iv got a spare one that burned on my header, i spliced it all back together and put an old 02 on it worked. i was using it on my buddys truck because he wanted it for some tuning and i thought it wold be cool to get a spare one working to keep in the toolbox, that lasted for 5 minutes then it threw code 2(sensor not plugged in) and i tried several different old sensors and checked over all my connections, just couldnt get it to work again... oh well.
so i guess ill do the heater calibration if it gives me trouble again(as if it were the first time starting it up), all i did with it when i put the new sensor in was the free air calibration. after reading the manual today i can see why it would give me trouble because the free air calibration is not what calibrates the lc1 to a new sensor.
well its been about a month and a half since i got the wideband working great and just yesterday out of nowhere, it gives out again. all it does is throw code 8, i tried to do the full recalibration, didnt help. iv been through 3 sensors now in less then a year, this is insane. i refuse to purchase another unit, they need to give me one for free at this point. iv got it way back in the exhaust system, extendo bung. theres no way im exceeding 900 degrees at the bung.
i need to figure out a way to ditch this junk. is there another company out there? can you tune equally as good off of an egt guage? i just cant afford a new $80 sensor every couple months.

Did you contact Innovate on this issue? I believe I am on my third sensor. Lost the first two first tuning season. then after permanent rewire of my startup prcedure and moving it back from header flange to ext pipe connection area about 14 inches further back and adding extendo it is now on I bet three complete seasons of use..
