Doesn't work that way, you can't adjust springrates via a controller. All you are adjusting is the shocks... there is only so much adjustment in shocks you can make, and then it still has to be withing the range for it to work properly with the spring.
Just leave it, They put a lot of R&D into it for the last x years, to get where they are now, you can't expect that it can just be changed for such a small market and still be as good. If anyone wants comfort, then perhaps they need to look for an alternative.
