hey guys ,lately my lc-1 has been taking longer to warm up. then just last week if i was driving for over an hour all of a sudden it would start flashing and read 7.4, like what it does when it first warms up??? its starting to take less and less time to do this. Is the sensor on its way out? i got it from diyautotune about 5 months ago. Ive tried reading a error code on it but nothing shows. i also just recalibrated it but didnt help

haven't you heard? It's LC-1 death season.

unfortunately it's not obvious what the problem is. pull your sensor and run through the whole recalibration procedure.

i did the whole recalibration, warm up calibration and the fresh air one. Unless im missing something??

Double check your serial cable and terminator connections as well as the other wiring to the sensor. see if jiggling it around changes anything.

Damn. I'm just about to install one. Hope I'm not going to have problems.

ya the wires are all fine, happens sooner and sooner everytime i drive it, if im going down the road and it starts doing it i can shut the car off turn it back on and it warms up and works fine for another couple minutes. guessing the sensors fucked

i just sent my "defective batch" unit in about a month or so ago. they sent me a free replacement. now i finally have a unit that will hold a calibration. wooohooooh!

It is probably also flashing whatever the overheat code is, I forget. It's in the manual. Surprised the LED is not flashing a code. Does the LED ever work?

BTW when it gets an error like that it will go to some preset AFR value which can be set with the software interface IIRC. The idea is for it to go to an obviously wrong AFR so you know something is up.

Same thing happened to mine. Wiring was OK, serial OK, did numerous full recalibrations, flashed latest firmware, added a heat sink, and nothing worked. Kept doing the same thing. I thought at first it was an LC-1 problem and sent it in to Innovate to get checked out. Nothing wrong with it.

So I replaced the O2 sensor and it started working great again. Now I know when it does that it is time to replace the sensor.

I hate LC1's because of this ****. I had an AEM once also, it just works, none of this dieing ****.

defective batch what now?

I'm running a brand new sensor. still does it. except rarely.

They are supporting a "defective batch" recall pretty much?

These need to be updated from time to time? Never knew this, how do I go about such?

BUY A AEM UEGO AND WIN. it is so much ******* easier to install,and the most important part is you can trust it, it gets the job done well. I had an lc-1, couldn't deal with its ****, replaced it with a uego and now its so much better. It matches up perfect with the ms, and doesnt take long to warm up. do it.

I get the flashing or holding a steady number. Can't say it's overheating, though. First time it happened I was driving in 20F weather and the car wasn't even warmed up. Most of the time it's fine, though.

Mines fine reading on MS, but the gauge doesnt read correctly...im going to try to recalibrate it, i know i almost melted the controler on my exhaust last year though :S

Even with the issues, I still like it over the AEM

Since their forum is offline I think you would have to call them.

Yup. I eventually got so fed up with the analog output on my AEM drifting around that I replaced it with an LC-1 and XD-16. No regrets.

I think the reality of the situation is that low-cost wideband technology is still fairly new, and most, if not all of the wideband systems on the market currently targeted at consumer applications are potentially a bit... marginal.
