Help with Innovate LC1: Error 8

Help with Innovate LC1: Error 8
So I've done some searching and found this could have several possible meanings, including a faulty sensor itself.
Mine works fine for a while, about 10 minutes last night then through the code. Pulled over reset everything and it worked again but only for a minute or two.
Got frustrated and put everything up last night. This morning it worked for about 15 minutes all the way to work. Then I left work about an hour later to get the office donuts and on the way back it did it again.
I would have to test again to confirm but it seems to happen if I get heavy in the throttle and let out. Does anyone have any good ideas or suggestions before I try buying a new sensor?
I have not done a free air calibration yet, I got too hot driving around last night to feel like crawling under the car and taking the sensor out of the bung.

I'd bet on the sensor being aged past usefulness. I've had
to replace mine (I believe from leaving it in the pipe too long,
with insufficient attention to powering it up before motor start).

That's the sensor IIRC. I ran mine full time in my fair-weather Camaro for several years. Only had to replace the sensor once. You'll want it to be warm to do a calibration on it...the warmer, the better. Otherwise, I think the instructions tell you to power up the unit for 2 minutes before calibrating. This is so the heating element in the sensor will warm it up enough.
Are you sure you're getting adequate power supply to the unit? If it's happening under WOT, I wonder if the power is being chewed up by the rest of the system causing the sensor to fault...

Well last night I drove around for over an hour with no issues with the new sensor. Did a tuning run to correct my MAF and put it up for the night.
This morning I let it warm up, fired it up, idle to operating temp, and headed out. I got about a block from the house and let out of throttle to go over a speed table, when I looked back down it was locked out at 27.8:1 again with Error 8.
Guess it's a wiring issue I haven't found or could it be the controller itself? Going to check with a voltmeter for 12v and clean my grounds, it's been really humid there might be some corrosion on the ground area.
Anything else I should check?

Check the connector where the wideband hooks up to the extension cable - I used to tape mine up with electrical tape because the little o-ring in there didn't seem to keep moisture out...

I run my LM-1 full time in the TA and change the sensor every other season. your problem is probably not the sensor or wiring, but the black unit itself. I had the same code and sent it back to Innovate for repair for a small charge. Call them to confirm.

I checked my wiring last night and all the cables for cracks, burns, cuts and came up short.
Went for a spin and had an Error 8 by the time I got 3 blocks down the road. I pulled into a lot and reset everything and had the code again before I could get out of the lot.
I sent Innovate an email since it was after hours, if I don't hear back by lunch I will call them and see about sending it for repair.

Hey Thunder,
Did you do a heater calibration immediately after installing the new LSU4.2 sensor...?
see page 23 (Error 8) here:

Yes, calibrated it right off the bat.
It started working again Friday night when I went to the track. Drove 2 hours there and ran all night without a hiccup.
Saturday morning it worked fine all day in a guys truck I did some tuning on and then worked in my car again.
Today I went to fix some issues (low timing and MAF table was lean by 6%) and it started failing right off the bat. Left it alone for the rest of the day and tried again about 8 hours later and still no go. The a/f jumped between normal and high 20s a lot then it finally froze.
The fact it is intermittent has me confused.
EDIT: Also I just realized the thread title is incorrect. It is the LC-1 unit. It is also inside the cabin of the car, nothing is outside but the wire running to the sensor itself.

LC-1 and LM-1 are similar...
check the wiring/connector... if it passes thru you floorboard/firewall, are the wires rubbing on the passthru hole, or are they crimped or bent sharply or pulled tight...?
wiggle the connector and wires, see if it makes any change;
if the problem persists contact Innovate and explain it to them.

Correct the unit did the heater cal automatically after it was re-installed.
I've been emailing Innovate support, he seems to think the issue is power or ground related. I think I'm going to try running those to more direct sources in the engine bay to eliminate that. I will also check once again to make sure I haven't put any of the wires/connectors in a bind.
Thanks again.
