New to E85. Getting a baseline...

I don't like the PLX units that much. They read wrong on a lot of cars. The cheap Bosch sensors that most of these systems use nowdays are a failure prone part (As are most Bosch electronics, just look at most german cars). So they fail and the AEM UEGO, Innovate, and NGK AFX boxes throw up an error or stop giving a reading, however, the PLX boxes instead keep "working" but it's a wrong reading. I would rather have it a "Sensor Error" on my screen than a 11.0 A/F reading when it's really 12.0.

I like to use the NTK sensors instead, they cost a bit more though, but they do last a lot longer, especially if you ever run race gas.

Narrowband emulation doesn't always work perfectly, depending on the wideband and the ECU it's used on. If you have a wideband and no real stock O2, you might just want to run in open loop all the time and tune for gas mileage.

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.

.

I never knew that about the plx units I might have to think of switching to a different one
