setup for cruise control with auto transmission

Postby larnor » Sun Jul 12, 2020 8:33 am

i'm in the process of trying to set up cruise control for a bmw e36 with an auto transmission that i'm converting to DBW.
My problem is that the setup of the cruise control insist on me setting up a input for a clutch switch,which i obviously do not have.
I have tried setting it up with the neutral switch function with no success, and the gear detection function seems to require the gear position sensor input type to be able to set it up for a auto gear selector.

is there anything i am missing,or do you have to set up the clutch switch function regardless? if so,would wiring that input together with the brake switch work?

Wiring the clutch switch in with the brake switch should be possible.

Have you tried setting up the gear detection over the gear ratios?
You can change the gear detection type in the functions page. However
you will need to set up a vehicle speed sensor for that to work.

wiring in the clutch with the brake switch is what i'll have to do then, i tried using the gear ratios and all the other options for gear detection too with no luck. it asked for the clutch switch to be wired in on all of them.

it does sound like setting it up with the gear ratios will be the best way of doing it though, the original ecu has a input for the right rear speed sensor signal going via the ABS\ASC system, plus i am planning to split off the signal coming from the transmission.
