Hello, I have built a BC in my Audi (see signature). Somehow the current consumption indicator or everything that has to do with fuel is not really promising:-( I have built in lt. Mecki’s FAQ. Everything connected according to instructions, I am happy that everything worked so nicely. Then test drive and….Shit:-( consumption is absolutely not right. Can it be that I have done the residual range calibration already so easily with a 1/4 tank volume? Please help me… rbrauch currently swings between 50.2 and 50.9 liters no matter how I drive…would have expected at least a 0.0 L in thrust. Can one possibly also attach the wrong consumption signal? Think that there is only one or?
