This is true, but there are limitations on most flex software due to that interpolation, which the elite doesn't have. I am seriously looking at the new 1500 elite for the evo for this reason, if it has the same adjustability with regards to ethanol percentage.
The Fcon Vpro has the ability to run a flex setup i'm sure, but no support to get it implemented. As far as strap-on dildo's go, it's still by far the best option available for the VQ25det.
