Thanks for confirming.

Switching pins would still mean that motor runs reverse internally and hill hold etc won’t work :(

Yeah hill hold still needs debugging in that case, same problem in Audi.

Another small note. Setting the dirmode to "SwitchReversed" also inverts the seldir.
Example: if din_forward = on, seldir shows Reversed. The motor spins forward correctly.
I was trying to use the seldir as the signal for the dashboard display, but need to invert it, I guess. rotordit only updates after actually spinning the motor, so cannot use that.

Forward needs to be forward en reverse needs tobe reverse...
Hi!
what phases have you changed programmatically? 1 - 3 , 1 - 2 or 2 - 3 ?

Peter,

What did you use for a pump? Is there a thread on this mod? Thanks
