I checked more or less all the parameters that are documented in the files. But, the cars doesn't work in this way.
I wrote a program to check/change the fuel consumption and the tank capacities that are "strange".
The result of the program is a list of all the cars parameters used for fuel consumption. Based on those parameters, the program calculates the final results (fuel consumption per hour and per 100km).
Example : Mini on Mid Ohio No chicane
Formula to get the amount of liters/hour for each car (found on rsc) :
Cons = Rad * AccelValue * FuelCoef * Duration * 60
- Cons = the fuel consumption per hour
- Rad the radians based on max engine rev/mn (Rad = MaxRev / (2*3.14159)
- AccelValue = Throttle value (0 to 1)
- Fuel Coef = the value "FuelConsumption=" from the engine.ini file
- Duration = 60 for a minute
Let take the mini with original values:
With an average throttle of 66%, the mini needs 121L/hour ! (On Mid Ohio, the average throttle value is 72-75% with the mini)
If I want to correct this and if I understood the principle, I have to change the "FuelConsumption" value in the engine.ini file.
So, after some talks with a "Racing Mini" Driver, the car shouldn't need more than 25L/hour
So, I just recalculate the new FuelConsumption value to get a final consumption of 25L/hour.
But, I changed this value in the engine.ini file and tested with the Motec (to be sure that everything is OK).
Résult : The Motec result (on 3 laps) is completly different !
For the 3 laps, I have need 321 seconds and 1.24L fuel.
So, 13.9L/H. That's completly different from the goal/real value of 25L/H !
That's why I'm trying to understand why the formula I found on rsc gives me such a big difference (not far from 50%) compared to the Motec...
Maybe the formula is wrong, maybe I did something wrong in my formulas, I don't know... But I hope I could find an explanation in the rsc topic. That's why I'm asking
