I'm now running open loop, but back when I was leaning out the closed loop with my wideband, I got it to work pretty good but it definitely took some dinging around with the output settings to get it right. The new firmware sucks on the LC-1, it makes the AFR jump everywhere and makes closed loop about impossible to even use. Even in openloop the AFR it shows flies all over the place. My cousins that came with the newer firmware is that way, and mine was when I upgraded the firmware; I've since downgraded mine and it works great again.
