Short long story, I borrowed my ex car from friend 1.8T AJL , and have noticed a really bad MPG.
I turn on logger and saw at autoban at cruise at 3000 rpm ignition was around 15-16°. It follow KFZW2, and doesn t try to reach KFZWOP2. As I remeber in this conditions ECU schould try to reach KFZWOP2. But never mind about that, so I forced similar KFZWOP values in KFZW2 and got around 30° at cruise on autoban. Car was much better to drive, quiter, smooother and with huge difference in MPG
But at full load, my ignition goes at around zero. Cant figure out why
NWS is used all time until 4000 rpm, and after that I have again normal ignition that follow KFZW
