thinking about ditching my LC1

After 30,000 miles of trouble free LC1 use. No cal or error problems. I desided to run evoscan for the first time in almost 2 years to download a SES.
Deleted code and then my LED quit working. Checked sensor - was cold. Power was getting there for the SSI4 was up. Called innovate and got a RMA for the old 7 wire LC1 unit. I believe it's due to heart failure in heater circuit.
I can't see a link between evoscan and lc1 death but it's weird with the timing of events. Next time I'll just reset the battery, it's going to be a 0300 anyway.

After an inital RMA 
mine has been working like a charm. Logging is great too. I will say that via the serial to usb connector the unit does not log as quickly as the other data. This happens when I only am logging a few parameters. Perhaps I will do the LC-1 connection to the ecu at some point. Supposedly that eliminates the laggy logging.

You get lag with the LC1 AFR? That is unusual, at least from what I've seen. Have some afr logs displaying single cyl leaning (was probably a dirty injector). Spiking showed a direct correlation with rpm and the ignition event down to 0.01 sec. Although finding what cyl was the culprit would be impossible, it did represent a degree of precision. Would be nice to find a way to run four O2 sensors on these cars without reading rich from psi and killing the sensor early.
Still waiting for Innovate to get back on what they find with my LC1. They've had it since yesterday, but are rude on the phone (hang up, discredit my "gounding scheme" they know nothing about, question my reason for calling)

LC1 has been on my old Evo for 50,000 miles and never so much as a single problem. I believe the new owner just replaced the sensor simply because it had 50k on it. I always calibrated by decel fuel cut before I tuned (calibration button was in my glove box). It literally took 5 seconds and I looked to make sure it went to 20.9% 02. No issues ever.

C6 the evoscan 2.5 has LC1 lag problems.
Hamish is fixing this as well as adding a new feature I told him about called 'go for recalibration'... Where Evoscan goes into a LC1 calibration mode, monitors IPW and sends a reset signal to the LC1 (via serial) when IPW is 0 for a long time... It should continue monitoring IPW while the cal is happening and then report back to the user if it was sucessful or not...

Happy ZT2 owner here. I know someone with an LC1 and I'm glad I don't have to calibrate it like he does. I also really, really like the ZT2 software. It's simple and works really well. I pretty much agree with everything TTP said above.

I'm probably the guy he knows with an LC-1. 
And now that I'm calibrating it with the decel trick instead of pulling the sensor out of the exhaust, life with it has been pretty good.
I will point out, though, that is extremely sensitive to power and ground (as others have mentioned). I have power coming off the lighter right now, and with a (relatively low power draw) tablet plugged in there with an AC converter, the LC1 completely freaks out.
Unplug it, reboot the LC1, and life is happy again. I'll be moving to a relayed source directly off the battery soon, which should eliminate the problem entirely.
