I've sent you a mail with drawing.

I think we really need to know just what this solenoid valve actually does to the motor (fuel, air, what...?) in order to know just what its action is; could it even be some kind of hydraulic valve, to operate something else (I dunno, like adjusting valve timing or summat...)? What KIND of motor is this (electric, gas turbine, steam, i/c,...?)

I think just what this 'mise au point' activity is is going to be crucial to finding the right term; I did wonder about something like 'peaking', but it all depends just what is going on.
Obviously there are lots of parameters that might be tested, like when the valve opens or closes, how long it is open for, etc.

All so many ifs and buts...

Don't know where you got 'box' from, but I'd be inclined to think it is more of a 'unit' or 'module'??

Boitier electro vanne moteur = motor solenoid valve (control) box
Presumably the box needs to be adjusted - microprocesores, timers, etc prior to the box being used to fine tune the motor? Feasible?

And yes, Chris, I do think there is a difference in meaning. We don't know what this BEVM is for, but it seems in some way to be used for the 'mise au point' of something else — I can draw a parallel with the focusing motor for a remote-controlled camera, for example.

So it seems to me that the word order 'BEVM de mise au point' is simply describing which type of BEVM it is; whereas the 'essais de mise au point BEVM' seems to be testing just how well the BEVM is doing its 'mise au point' job.
However, I can't go any further than that, having no idea at all what sort of system this might be or why it might involve any form of 'mise au point'.

I suppose it is possible that this has been unintentionally entered into the table twice.
