What a bug?

Something I am not lucky with ELMMI. Or this is a bad contact somewhere. At first, I was delighted: I connected ELM, started, opened the Hobdrive program, put the type of Nissan Custom JD into the "Parameters of the car". Accordingly, the Nissan Custom put in the initialization line of initialization. Everything, I didn’t change anything else. Immediately connected to the phone, but again for some reason without interfacing with the code. Here shows all the data available in the free version of the program. The connection with the telephone is periodically lost, quite often, and there are difficulties in re -connection. I don’t understand anything..And it did not work out with the CAR GAUGE program. Maybe the settings additionally need to correct? After starting the program, I pressed the fork icon, there I chose Nissan. Then he chose different modules (ECN (Gasoline), ECM (Diesel), TCM, ABS, SRS, BCM-40, BCM-42). In general, what you need to choose? Then he put a checkmark when choosing an OBDII device. But it did not work out to connect. The testimony of fuel consumption in the Hobdrive program was very alerted. On idle after movement, in general, there were about 5,000 liters per 100 km. It is clear that it drives. But after several minutes of movement, this indicator began to show stably 30-35. What a bug? In general, the following data showed on the sides: instant consumption 14.5 (when the gas pedal released, respectively fell, liters up to 7) short -term consumption 14.0.I really drove through the cork and a very small distance. I'll go through tomorrow if it is normally connected. This is a marriage again, such symptoms were? The third or something to order..And please help about the expense what readings of the sensors to watch in order to evaluate what you need to change (lambda, MAF).Generally acquired this device for evaluating gluttony, otherwise after the purchase is not very pleased with the consumption. Consumption on idle after full heating turned out 0.9 l/h, but not less. Frost truth on the street, -21.The testimony of lambda on idle rode from about 0.1 to 0.7.
