Does anyone know if this thing works? and how? i mean i want to set my A/F ratio back to where it should be and i dont understand how this thing does it or if it even does...any help is appreciated

 

I have one, PM me.
It does have a narrowband output, but it is programmable.

 

all it does is tell you accurately what your afr is. it doesnt adjust it. you some sort of ems for that.

 

What doood said.

All the LM-1 is good for is telling you the reading of your air fuel mixture. It is not plugged into the ecu or able to make corrections/tune your car. You need other stuff for that.

The narrowband output is programmable, so is the wideband output. They can both be setup for wideband (0-5V), or both be setup for narrowband (0-1V). So if you don't have it setup right, your car will get the wrong readings and run rich or lean to compensate.

You can tell it that 7 AFR is 0V, or you can say 10 AFR is 0V, or you can say 15 AFR is 0V.
RTFM
