Don, you are correct – its current that is applied to the valve that changes its characteristics. There must be a value for the modes (map) as baseline for a range the valve can work through???? (It might include high and low range values????) It’s this admap value I cannot find at the moment. (You can see it shows 0 as this is what its being told by the controller I assume)

As the system is semi active it will vary the current depending on a number of variables and just looking at the info being fed to a valve when sitting still is likely to be the same in all modes.

Ill have some free time this weekend and will see what else I can see and if changing between modes changes any measured values.

Thanks,

Chris
