which is the most appropriate source code for the Arduino(atmega 168)
I B4 Passat TDI
I am from Romania and I need units of measure kilometers and liters
Thank you in advance

I used this code: You have to modify it slightly to work on the Passat's fuel consumption signal. Find this line in the code:

attachInterrupt(0, processInjOpen, FALLING);
attachInterrupt(1, processInjClosed, RISING);

and change it to:

attachInterrupt(0, processInjOpen, RISING);
attachInterrupt(1, processInjClosed, FALLING);

More info on it here and here.

Good luck!

I finish mpguino
I installed on car
calibration fail
I used code 075
yetimus you what values to use VSS pulse / miles?
the calculations and the board is clear indication that the value of pulse / km would be about 2138 pulse / km, but the information is incorrect
sometimes show the real speed sometimes appropriated to 100km / h over
I think the information is correct injection fuel value is correct

I did upgrade to mpguino with atmega 328
I used code 080 to indicate l/100km with Arduino 13
mpguino not indicate anything, the speed of 000.00, 00.00 instant tank .....
I entered as code 079 and 00.00
I entered code 075 as one who works well with atmega 168 and runs on 328 as well but now the tank instantly indicate l/100km
I entered the fog do not know what to do
