Hello, i have a problem with fuel countaty in my audi A2, it takes 6,5l/100km cruising at 100 km/h, and in town it uses uo to 8,5l/100km. i have managed to make more fuel economy to 7l/100km at town and 6l/100km out town by playing with synchronization, and taking the fueling addaptations to lowest places, btw, it will not frow any black smoke as usual 4 cyl engine, and when playing with ignition the start of cold car was OK, even better with offcet up to 7CF, the starting was stopped only by ecu, when the sensor was out of range, but the car i assume would satrt OK, is it realy ok for PD engines? How can i lower connsumption? i have 182426few screens. btw MAF seems to be OK.

182427MAF on usuly around 330-360.

182428MAF off if no accelerator pressed 100, if i press accellerator once then it goes to 0, if i press it full then goes up to 539 and stays there.

182429MAP seeams to be better then MAF, as it keeps the data +- 20mbar from specified.


182430

P.S. Intake is OK, i have clean everything up to EGR and it too, and the exhaust is ok too. :)
