......on Bank 2 sensor 1 so I plugged the LC-1 into B2 senser 2(post cat O2 plug). I got an O2 bung welded up today and seem's to be working good with my wide band, my car seems to run way better with the stock O2 instead of using the simulated output of the LC-1's output's in place of B2 sensor 1, I just plugged my LC-1 into the postcat O2 plug and now I'm using output 1 of the LC-1 as a post cat O2 simm and sending the other output 2 to my scanning software, I't works geat that way and I have no O2 trouble codes yet. Knock on wood. Just trying to pass on my experience.
