LC-1 users come in Got my lc1 all wired up as a wideband and narrowband and seems like it's working....I'm getting readings on my digital dynotune gauge. Couple things though:
1. Logworks won't connect to the lc1, all the gauges stay grayed out even while I'm getting readings on my dynotune gauge. I've read on Innovate's forum that I need to update to logworks 2.0 to fix this, but when I go to their page to download it, they say "the page you requested is not available" and it gives me their site map listing. Am I missing something here?? How the hell am I supposed to update? Does anyone maybe have the 2.0 installer they could email me?
2. What kind of AFR readings do you guys see at idle? I'm consistently seeing 15.7-16.1 idling. Sound lean at all? It shoots down to 13-14 when I rev it a little.
Thanks guys!

Ok, got logworks working finally (thanks HavATampa!!), started the car and my dynotune gauge and logworks were working perfectly...fluctuating between 14.5 and 15 during closed loop idle. So I shut the car off and then turned the wideband back on and flashed the voltages I wanted in there to log wideband w/EGR through HPTuners (10:1 afr = 0v and 18:1 afr = 5v). Then I set up my PID's in HPT, started the car and started scanning. Now everything is puking all over the place. The dynotune gauge is reading 50:1 afr and logworks jumps all over the place, then logworks goes to 20.9 and stops working, my LED starts blinking and the gauge stops working. I tried setting the analog 2 output back to default, reset the whole lc1 calibration....still the same crap, didn't fix anything. Gauge shows 50:1 in open air now, where it used to show 20.9. Anybody have any clue wtf happened?? It was working perfectly until I changed the analog 2 output and now I can't get it to work at all. Help!!! This stupid LC1 has fought me since I opened the goddamn box.
My grounds:
heater is going to chassis ground, calibration wire is going to diff chassis ground and the rest are grounded through the EGR harness to the pcm (I think). Should be fine since it was working perfectly until I changed the output.

Update, I just tried the following:
Took sensor out of exhaust and flatlined the analog 2 voltage at 2.5. Measured voltage with multimeter at egr input (where analog 2 is connected) and got 2.5 volts. Checked it in hpt, 2.5 volts. The dynotune gauge changed to 25:1 instead of 50:1 like it has been
. Flatlined to 5 volts, egr input measured 5 volts with multimeter as well as hpt scanner. Dynotune gauge went right back to 50:1. I checked logworks just for giggles and it said 20.9.
I recalibrated everything in open air and then put the sensor back in the collector. I set the analog 2 back to default settings. Now logworks is showing the correct 14.7afr at idle, hpt is showing .61v and ~10:1 afr (I used the EGR writeup sticky for my pids, so they should be right) and a multimeter showed .60v at the EGR input. Now the dynotune gauge is at 6.0!!!! WTF is going on??? It seems the lc1 is working correctly now through logworks at least, but my analog 2 output seems fubar'd. It flatlines voltages fine but it's not putting out the right voltage to the gauge and hpt once the car is running. Seems to me I should be seeing around 3 volts on the analog 2 output instead of .60---I'm so lost here.
Any ideas?...will try just about anything.

sounds like you fried your DAC (Digital to Analog Converter in side the cable)
If logworks reports the correct voltage, and you're sure the analog outs are configured correctly (which if you restored to factory defaults... the voltage should fluctuate a little), and the analog output voltage isn't changing then your DAC is dead ... time to contact innovate to see if they'll warranty it for you ... then in the future use a resistor between the output wire and the source (I forget the ohm rating... you're probably setting, search innovates web site... this is all over their forums)

When you find out what it is please post up. I am having the same problem with mine. I didn't get a data cable with the LM-1 that I am using but I am getting it tomorrow. My buddy just forgot to give it to me. I figured that I was seeing what I was seeing becuase I needed to define the voltage range. I am curious as to what they say to you. I am doing the same thing w/ HPT logging the AFR thruogh the EGR. Subscribed!

UPDATE:
Just got off the phone with Innovate tech support, didn't take 5 minutes. He didn't do any troubleshooting at all, I just told him what was happening and that I thought the DAC might be dead. He had me email my contact info so they can start an RMA for a replacement. Good customer service!
Apparently this problem is not uncommon, and there's a newer version of the lc1 with build in resistors to save the DAC from a fatal surge. Hopefully I'll have better luck with the next one.

Received my lc1 back in the mail today, it took a little over two weeks. I was under the impression it was being replaced with a new one, not repairing the one I had. Oh well, I'll hook it up this weekend and see if I'll be pissed or not.
