Retrofitting a 1986 Maho MH400E

Thank you so much! I'm looking through your files. I'll definitely let you know the results!

net sig_reducer_left_center  mh400e-gearbox.reducer-left-center <= hm2_5i25.0.7i84.0.2.input-03
net sig_middle_left_center   mh400e-gearbox.middle-left-center  <= hm2_5i25.0.7i84.0.2.input-07
net sig_input_left_center    mh400e-gearbox.input-left-center   <= hm2_5i25.0.7i84.0.2.input-11

I don't have such inputs on my machine. They are on the 28A1, but they are not in the loops. They immediately increase the resistance when triggered, but do not go to the controller. Can I configure the switching without connecting these signals?

You will need to modify the gearbox comp and recompile it. I didn't write it myself, it was written for me by a friend, so you might need to find someone to do the code changes.

Hello
I figured out the center positions (muted them in the HAL, combining them with the middle position).
All gears shift perfectly!!!
The only thing I can't figure out is why F9 always engages first gear
and after the spindle stops (with any stop command), the transmission shifts to neutral. Is this how it should be, or have I messed up something in the HAL?

That shifting into neutral also annoyed me. That was corrected. Take a look in the github for some revision he did. That made it stay in gear.

Not sure way you mean by F9 engaging low first gear?
