BMW M5 5.0 V8 400hp e39

ECU: Siemens MSS52

SW: 7837965 HW18 61104DB2 1601

Read write: Alientech Kess3 OBD

We worked on BMW M5 e39 ECU software to disable faults regarding CAT.

B2 - “Catalyst system efficiency, Cyl #1-4”

B3 - “Catalyst system efficiency, Cyl #5-8”

Disabled rpm's when CAT diagnostics are enabled.  (K_N_MAX_KATS)

Also, we fixed Dyno rev. limit from 5700 to 6800, no more fuse removing  (K_N_MAX_VFEHLER)

We also can delete from ecu most of faults if necessary.
