Symptoms of a Bad Innovate LM-1/LC-1?

[praedet]

All right fellow tuners. I had heard that the LM-1 set-up has a high mortality rate, but I guess I was hoping I would be lucky

 

Anyway, after using mine for about 6 months w/ no problems, this is the output I was getting out of it today. I have 3 logs that have this same behavior in them, so here is a small snippet where you can compare to the Car's O2 and see the fact that under open-loop coasting, the LM-1 does not even register it...

 

Thoughts? Is the LM-1 gone? Will Innovate cover it?

Check the 7 wires, do a dance and hit the "calibration" button and stare at the LED

 

Sorry to hear it

 

The sensor's themselves are not all that expensive.

[praedet]

Is it the sensor, or the actual Innovate part? I am going to do a cal in a little while. Here's hoping...

 

The random zeros, and the fact it isn't ever seeing the 20+ during coasting, make me think it is shot

[rao]

Probably the Innovate controller. Maybe you had the grounds too close together or too far apart

 

Give them a call and see what they say tomorrow; be sure to tell them that you calibrated it every time before you started the engine

 

It should be giving you an error code. Check out the manual - http://www.innovatemotorsports.com/support/manual/LC-1_Manual.pdf

Bump for new lookers on a new day

 

Calibrated it this morning, still the same issue after

My LC-1 still works fine... I think. I haven't logged in a month or so. I think I've seen a few blips on 20.33 on mine, but pretty rare as I haven't seen any show up in logs nor any zero's in logs.

 

I'd replace the sensor. Then you'll know whether the sensor or the control unit is at fault. You'll need the new sensor sooner or later anyways.

ground black wire, pull out sensor, let it figure out what stoich is . Reset is your friend.

Mine works flawlessly in ST-A and Logworks, but it gets flakey in RR once in a while and starts spitting out seemingly random numbers. It has even gone the wrong direction from 14.7 during WOT runs before too. I just go over to the left and de-select the LC-1 and re-select it. It usually goes back to normal operation for a while at least. I hit 20.33(the lean limit of the sensor) when coasting in gear.

Remember that if you installed it with the reset button(or ground it out to reset it); you need to remove the WBO2 sensor from the pipe to reset it. If you reset it with the sesnsor in the pipe it will be off by a little.

 

Have you adjusted the LC-1 read rate in the programmer software lately/ever?

[mwiener2]

calibrate it in open air

[Legend]

calibrate it in open air

 

Or calibrate it in the morning after sitting overnight. No wrench required.

[mwiener2]

still do it in open air,

 

water vapor would be the biggest thing, but other stuff can sit in the pipes for a long time. The heating cycle of the sensor can cause the water vapor to heat up, among other things, and throw of the readings.

 

 

always calibrate in open air

[Legend]

I didn't use anti-seize on the O2 sensor and I don't have a lot of faith on my welded bung. I want to minimize the wrenching. I agree open air would be best but I'll continue to calibrate in-pipe.

[praedet]

Well, no change after calibrating in the pipe (after the car sat for about 12 hours)

 

Interestingly, the log/sensor seems fine if I use the Log Works Innovate software. I am just seeing the wierd stuff w/ romraider. Any thoughts?

[praedet]

All right, so now I can log w/ Romraider again...

 

I have no idea what changed. Oh well. So, which SHOULD be more accurate, the OEM O2, or the LC-1? When only looking at closed loop logs, cutting out anything above 15.2 or below 14.2, my LC-1 averages a reading that is about 0.25 higher?

 

Should I be worrying about this for my WOT runs (should be more conservative that way)

[Legend]

You're going to have to calibrate based on the OEM 02, right, since that's what your FT's are based off of. No, I wouldn't worry about it for WOT runs.
