I have a Lc-1 and I'm trying to wideband tune my car but I don't understand how. I'm not gonna make any changes at all until I actually learn what to do. I recorded a 40 second session of my car idling around 1k and the af ratio was not steady at all. It kept fluctuating between 13.6 and 14.14 but mainly staying under 14. How can I correct this, or is this normal?
