Hello all,
The thing that I love about Torque is the ability to add custom pids and formulas.
One thing that I miss or I just don’t know how to do, is related to the fuel level.
The fuel level button only allows us to fill or empty the tank by 25% steps.
At least, whenever I go to the gas station, I fill my tank in liters (or gallons), not percentage.
So I am wondering, is there any way, by using OBD commands or a virtual PID to solve that issue?
For example,
R = Fuel remaining in my Tank. (% from [ff1271])
T = Total capacity of my Tank. (liters, from the profile or user input)
F = filled volume at gas station. (liters, user input)
Whenever I fill the gas, I would enter the gas volume, F, so that:
R = 100*((((T*R)/100) + F)/T)
Or
R = (100*F + R*T) / T (%)
So that the PID is updated with the filled volume.
Another interesting thing is to update the fuel costs, also.
C = current fuel cost per volume (pid?, the one that provides the $/mile)
N = Filled gas cost (eg. I spent when I went to the gas station)
C = (C*(R*T/100)^2 + N*F)/(R*T/100)
(so that the program calculates the actual gas price inside the tank)
For example:
My tank has 40 liters of capacity.
I have 20 liters of gas, that I have paid
T=40
R =50%
C= 15/20 = 0.75 $/liter
Then I stopped by another gas station,
and filled 10 more liters at the cost of (yes I was dumb)
N = 25$
F = 10 liters
Cnew= (0.75*20*20 + 10*25)/30
Cnew = 18.33 $/liter
As for the R
Rnew = (100.10 + 50*40)/40 = 75%, after filling the gas
