Hi!
I'm doing right now conversion of 523i E60 into 525i. Intake manifold with two DISA valves is now installed but now I'm facing one problem that surprised me. I changed typeshlussel to NE51, ISTA/P found new software for DME, programmed it and now I need to change power class parameters coding... As far I know I need to reset working hours to code new class in DME using NCS Expert. How can I do it? Or someone can help me. I have Kess V2 and K-tag. Can it be done via OBD? And how about CAS? I can't change power class in it using NCS Expert... Will it code after resetting working hours? Waiting for help ![]() |

(I coded ECU also after flash) any further ideas? .:: Thanks+Rep doesn´t kill anybody
