Default LC-1: Full lean, then LED off, then full rich

I just got my LC-1. I've attached my LC-1 to my honda ECU according to the instructions here:

https://honda-tech.com/showpost.p...37&postcount=9

Wiring is double and triple and quadruple checked. I've checked voltages at the power and signal wires when it's running with a multimeter to make sure everything is good. I've soldered what can be soldered and used dielectric grease on all the connectors.

Everything is brand new. When I first started the car up, everything worked fine. I got readings that I was expecting. My car was running a little rich, but i knew that already. After driving less than a half mile down the road, it quit.

Now when I turn the key on, the sensor heats up and the LED does it's blinking thing until it goes solid. Then I start the car and it reads full lean under any throttle conditions. After a few minutes the LED goes off and it reads full rich under any throttle conditions.

What can I check for or has my sensor gone busted already?

I have gotten numerous faulty products from Innovate straight out of the box. I am nowhere near a satisfied customer.

Call them and ask for an RMA.

I'd like to troubleshoot the problem first. I don't know how to tell if it's the LC-1 or the sensor. Anybody know what to check?

With the sensor plugged in, backprobe the wires coming out of the O2 sensor connector and let us know which wires have power & gnds(during sensor warm-up). Innovates supplies the pin-outs in their online manual if you'd like to take a look at them.

Pump has +5v
Heater has +12v
Sensor has low positive voltage
Heater ground OK
Pump/sensor ground OK.

When I rev the engine, the LC-1 output doesn't change from full lean. But when I check at the sensor, both the sensor voltage and the pump voltage do change.

I received a code 8 during this. I turned the engine off and then back on and the code went away.

After a few minutes I turned the engine off, then turned the key back on. The LC-1 went through the heater start-up, went solid for a while, then the LED turned off. Sometimes when I turn the key on, the LED doesn't come on at all.

OK, I cross posted this over at the Innovate forum hoping for a response. Instead, I have been banned from their forum and I think my post was deleted. I'm determined to be patient about this, but that's getting a lot shorter. I've emailed their tech support and I'll call them tomorrow. In the mean time I'm going to try reloading the firmware after going to Best Buy to get a conversion cable.

Well, I got a serial to USB cable. Got the drivers to install after a little work on Windows 7 x64. I tried updating the firmware and it took a crap halfway through. Now it won't do anything. So I've just requested an RMA from Innovate to have this repaired.
