Is the PCM required

We aren’t using pneumatics this year, are we still supposed to mount and wire a PCM?

No, you shouldn’t need a PCM

Thank you! It wasn’t very clear in the manual.

Actually, it is still permissible to have pneumatics actuators and not use the PCM. Spike relays are permissible for both the compressor and pneumatic solenoid valves per R53. I wouldn’t advise it, but it is legal.
