According to that product description yes. It says I quote:

"0-4v data output feed for ECU, data acquisition unit, or Laptop tuning"

So you would connect the gauges' output into one of the external voltage inputs and make a PID in the calc_pids.txt file that calculates the AFR according to the voltage that the gauge outputs.

so this can replace the lc-1 is was about to buy

I have never used that gauge before but according to the "notes" on the Auto Meter page that gauge will work fine with EFILive. Most likely there will be an equation in the instruction manual that will give an equation to convert the voltage output into a AFR for AutoVE or whatever other tuning you plan on doing.

From the instruction manual included with the gauge:

"The Auto Meter Wideband Air / Fuel gauge has a signal output for supplying information to a Data Logger or engine management system. The signal provided is a linear 0-4v output. See the BGD Range Setting Mode for information about how to define the air/fuel mixture values for low (0v) and high (4v) ranges of the output in order to scale this linear signal output for best operation with your Data Logger or engine management."

I read through the manual and it looks like the red will go to positive, black to ground, and the blue to the V1 or V2 ALSO you will want to run a ground from the gauges' ground to the V1 or V2 this will result in a more accurate voltage reading.

So according to the settings in the BGD Range Setting Mode the equation will differ depending on where you have the limits set. The equation is always linear between these low and high values. So if you set the low at 10:1AFR and the high 20:1AFR (gauge limits) your equation would look something like "({EXT.AD1}*2.5)+10"

That gauge looks like it can do A LOT of stuff!!! lol

Once you got your tune close you could change the high and low values so they were closer to 14.6 and then the equation would be:

({EXT.AD#}*m)+low -----> where m= (high-low)/4

Don't forget to change the # to the analog voltage input number that you are using.

Hope this helps!

thanks, when i get it I'll chime back in and let you guys know whats going on, thanks again
