We are an LV Hybrid team with an inboard motor. We use a KTM 390 engine, we are thinking of implementing pneumatic shifting for next season. The problem we are facing is we are not able to achieve a half shift with pneumatics for the neutral gear, which lies in between the 1st and 2nd gears. Other teams which use pneumatics, how do you guys achieve that with pneumatics ?

Or we are open to other suggestions for gear shifting mechanisms as well.

We’re facing an issue with our Emrax 228 + Bamocar D400-400 setup.
With the car lifted on jacks, we completed precharge, gave RFE/run, and APPS input. The motor ran normally in the correct direction.
After putting the car on the ground, precharge initially failed 2–3 times, although the TSAL was green. We fixed the precharge issue.
Now, after successful precharge + RFE/run, giving APPS input makes the motor run in the opposite direction, causing the car to move backwards.
Setup:
Emrax 228
Bamocar D400-400
Orion BMS 2
Dual-channel APPS
Any idea what could cause the motor direction to suddenly reverse? Could this be related to the controller parameters, resolver feedback, or CAN commands?
TL;DR: Motor worked correctly on jacks, but after putting the car on the ground, it now runs in the opposite direction despite the same RFE + APPS procedure.
