What AFR values are you using in the LC-1 the represent start of lean and rich?

 

I've tried so many combinations ... currently it's (I think) 15.4 @ .9v and 16.1 @ .1v.

I've tried a wider AFR range with a 5v like response ... a super tight range with about .3 AFR span. I've closed the voltage range as well. So far, the best results are around 15.3 @ .82v and 16.1 @ .12v.

 

Sorry to bring this back from the dead but has anyone had any further luck on this? I too am averaging about 14.3-14.4 at idle and cruise with my LC-1. I am just wanting to make sure this is an LC-1 thing and not something else. I am strictly using the LC-1 as a WB not a NB.

 

Same here, averaging 14.2 on my LC1 in closed loop. Still using the stock front o2 sensor, LC1 mounted in my testpipe.

Any answers?

 

This same thing is happening to me but with my evo prosport wideband gauge. I idle around 14.1-14.4 and I cruise at 14.1 consistantly. Iv tried everything.. Replace my front o2 and clean my maf. Any help would be greatly appreciated. Sorry for bringing this thread from the dead

 

Glad you did. I have never gotten an anwer or figured it out myself. Logging cruise, the target AFR is 14.7, but my car always hovers around 14.3-14.4. Also changed the front O2 and tried all kinds of stuff.
