Downshifts are very satisfying and sound awesome with catless headers and MPE. Damos for E-series 8hp are impossible to find as of now.
2: Adaptive cruise control doesn’t work in 8th gear. Max 7. So will be lookibg for a workaround. Other possible solution is E70 acc with stop and go, those will understand 8 gears.
3: only EGS error that i get is about a missing signal from the airbag module about missing a missing message on the pt-can about the seatbelt. Strange enough, gearbox stays in D with seatbelt insterted and door open.
4: Still need to finish the wiring and code my CAS properly. There is still a possibility that the CAS needs replacement to get rid of all DTC’s. BMW ETK says that cas is a different p/n with 8hp. Paddles and pa_bus are still not connected to my new DME and gearbox. Probably explains my EWS4 dtc in DME. According to newtis, cars with EWS4 have that wire connected between CAS, DME, EWS, steering lock and comfort access module. Will be researching later. Busy with new interior right now, will be removing my extended leather dashboard for a standard one with other seats

i think there should be DSC from E89 or E84 2012+ which support adaptive cruise at 8 speed and/or firmware for old modules for that compatibility
