Hi guys-
I just took my exhaust system all the way apart to fix an exhaust leak at the cylinder head. I have everything put back together and put the LC-1 sensor back in the downpipe, and it is reading way rich when I think I'm richer than stoich, and pegged lean when I'm leaner than stoich. Needle on my TS gauge is all over the place during normal driving.
Sensor placement is good, right at the first bend in the downpipe. Was reading fine before I took it all apart. Wiring did not change.
What do you all think? Is the sensor toast? Would the wires getting a little twisted when I took it off affect anything?

Re: LC-1 Showing Wacky Readings
I'm not an LC-1 fan, I went through three of them within a year on one car, two controllers replaced under warranty. Ultimately I just threw it all into the trash and got an AEM, worked perfect. Having said that I'd first check to see if you can still communicate with the controller, if not then yes its toast. You can and should also do a free air calibration.

Re: LC-1 Showing Wacky Readings
Interesting you say that. I am actually using an LC-1 because I couldn't get the new LC-2 I bought to work.
I have verified I can communicate with the controller. I s'pose I'll try another free air cal and buy a new sensor if that doesn't work.
Thanks for the tip on AEM- I'll have to try one of those next time.
