I've made something like your looking for there is one thing you'll have to check first and that is if your car is reporting fuel level.

If the vehicle reports that then I just added it manually in the PID creator.

PID (Empty)
Long Name ("Distance to Empty")
Short Name ("Dist to E")
Minimum Value ("0")
Maximum Value ("1000.0")
Scale Factor (1)
Unit Type ("Miles")
Equation ("(([2F]/100)*17.5)*[ff5201]")
OBD Header (Empty)
This works on my car my tank is 17.5 gallons so adjust yours accordingly. If you car doesn't report fuel level as a standard PID then you would have to find a extended PID and it would take a few more steps to get something like this to work. Just a FYI [2F] is reported fuel level and [ff5201] is running average MPG.

I would like to make a custom pid for a distance to empty gague..

I was looking at this:

"Name", "ShortName", "ModeAndPID", "Equation", "Min Value", "Max Value", "Units", "OBD Header" "Transmission Temperature(Method 3)", "Trans", "0105", "A-40", 0, 200, "C", ""

as an example to put in a csv file on the sd card...

Could someone point me in the right direction on getting this going..

I figured I would have to use the ammount of fuel % calculated with the Tank volume (manually entered I would assume) then figure out how to get a dte value with the mpg average...

Man this is exactly what I am looking for.. Luckily my car does report fuel level readings...

Thanks for the quick response! =)
