Default LC1 wide band question

i have an inovative LC1 wide band and i believe its a XD16 gauge... now i have it wired into my interface for my Hptuners. on the Pid it reads normal for A/F now on the guage it reads off from that. like for example 4 to 9 i havent paid attention if it reads lower or higher but thats the range i know of. Any reason this is like this?

You need to make sure HPTuners reads what the XD-1 gauge reads...the XD-1 is being fed by a different signal that isn't subject to calibration or setup issues, so it is indeed the truth source. Can you give some more details of what exactly is going on? I'm kinda lost...

someone had mentioned on another site that my gauge might need recalbrated using the serial cable?

The gauge itself only reads and displays what the LC-1 tells it...at least the number portion of the XD-1. The only thing you can calibrate on that gauge is the "needle" portion, as you can assign the range of AFRs to display around the full sweep. You can, however, calibrate the LC-1 itself, and that is where you need to pay close attention and make sure that the HPTuners interface and the XD-1 are reading as close to identical as possible.

I know my guage has the voltage ranges for 10-1 and 20-1 that you just program into it and then use the other output wire.

You didn't read his post, the number being displayed on the gauge during cruise is not 14-15, it's 5

^good catch.

well then the lc-1 is not programmed properly as 10.0 is as low as it should ever read.

i have an lm-1 and an lc-1
the lc-1 reads about .6-.8 richer than the lm-1
i did free air cal on both, same deal
i replaced the sensors on both, same thing
i kind of believe the lm-1, it seems to be more forgiving, where the lc-1 needs cal more
i even used a heat synk on both sensors

The first digit being out makes sense to me, because 14.7-15.2 would be right in line. 4.7-5.2 wouldn't even be lambda readings...
