lc-1 reading way lean
Before you ask, I did the free air and heater calibrations with the sensor hooked up sitting on my valve cover. I then disconnected, installed, and re-connected the sensor.
I get a E2 error, only blinks about 5 times on start up. It will warm up, read H10-H99 then will start to read AFR. Problem is, it reads in the high 20's low 30's when cold. If I give it a blip, it will dip down about 5 then shoot up to around 50.
So my question is, did the sensor calibrate wrong? Is the sensor bad? My white, blue, and gauge ground are all soldered to the same ground lug. Should I force another heater and free air cal? I can't tell what voltage yet, I need to grab the wires so I can hook up to laptop, do you think that has something to do with it? Is there a reset so I can reset it back to original configuration? Thanks for any help.

Reading crazy where?
All of these devices are microprocessor controlled and can be individually calibrated to different scales. Where are you reading this? An Innovate gauge? A third party gauge? An MS? Do you have a multimeter to troubleshoot with?
Also, never, ever solder wires to a lug for use in a high-vibration environment. Never, ever, ever.

I just double checked, it is hooked up correctly. I reset it once again to factory defaults, and it was set at Custom so I switched it back to Gasoline. I think that may have been my problem I didn't recognize it last time. I free air cal'd it twice and both times it settled on 20.9.
So now I start the car, and it idles low 20's. When I touch the throttle, it shoots to under 10. If I hold the pedal to the floor, it misfires like crazy and the gauge stays under 8. I have a feeling this has something to do with my clt sensor not being hooked up. I am still chasing down that problem. Maybe tomorrow I will just hard wire it and see what happens.
Also, after about 10 minutes of running, it flashes E8. So I need to move it farther down the exhaust. Yay. Any tips on doing this without a welder? Or is it impossible? Thanks for the help so far!

I've got an entire write-up on error 8 here:

Requires a firmware upgrade to the LC-1. Fortunately, you can do that yourself and the firmwares are in my write-up. I did the firmware update 3.5 years ago and it's been trouble free ever since.
You using a custom ECU or the OEM? Can't imagine how the car could idle at 20:1.

So at idle it's reading between 20-30.
On Decel, it's reading 20.9
On Accel, it's reading rich around 9-10.
At cruise (2nd gear going about 25mph) it's around 14-15.
So, I think it's reading right, I just have a bad misfire condition at idle. My timing light furthers my interest. With ten and gnd jumped, my timing light will skip every now and then, indicating a misfire. So now I need to figure out why it is misfiring at idle. If it is at idle it probably is at speed as well. Bleh.
