Just back from a spoiler test ride and the definitive answer is in:
on the 90D the spoiler is definitely NOT inactive.......once I hit mid 40's it tipped down dramatically.
Well, well, well. Thanks for this. So that leaves us to wonder if this is something just limited to the early 90Ds (before they're able to implement fixed spoiler), or just a communication snafu at configuration, or what. I'm hopeful nobody purchased the P90D exclusively for the purpose of getting an adaptive spoiler - if they did, I'm guessing we'll be hearing from them shortly below.
