So I have my wideband sensor setup and was able to configure it in HPTuners to have realtime readouts. The problem is I think its reading at 1/2 of what it should be. Could the formulas I'm using be wrong?

Here's what I currebtly have set for them both:

AFR (input/68.05) + 7.36 = output

EQ Ratio (Lambda :(input/1024) + 0.5 = output

Anyone have something else you're using currently?

Curious as to why you didn't go with the tried and true AEM 30-0334? That is what 90% use on this platform.

This one I'm able to link to my P3 gauge instead of buying another gauge to hookup.

This thread might be helpful. I haven't messed with any LC/LM widebands in years since the AEM OBD2 unit came out. But I do recall there was some extra work required to get it to work and report properly.

I was looking at this link last night but didn't read deep enough. I looked further and used some pointers and did a little thinking. What I did was monitor the lambda on logworks (the software innovative uses) and played with the math on HP Tuners until I had them both matching. The screenshot attached is the math I used to get it working but the readings look good to me. I'll let you decide on that one though.

@WiggyB any updates on your setup. This is the direction I'd like to go. I really don't want a pillar mount gauge or an extra gauge plopped on the dash somewhere. I really like the slick installation setup with this, plus the fact that it can be hardwired into the OBD2 connector.

Naw.............. I thought what was posted above was the answer but man was the car running rich. I gave up and went with the AEM. The problem was it kept reading lean so we kept dumping fuel into it and it was the exact opposite.

Thanks. Was hoping you figured out some magic. AEM seems they way to go, especially if you need help as that is what everyone else is using. Path of least resistance and all that.
