I think plenty of people see the Xede as a very capable engine management solution.
I also think plenty of people do not have the confidence and experience to be left alone with it, and they know this. Hence, they buy a UTEC and are not left alone fumbling in the dark with something nobody knows about.
Xede was last to market, not priced to make people consider it strongly enough as an alternative to the UTEC, not marketed for crap in the US, etc...
How many people are at levels where they care about converting MAP to MAF... and are still using the stock ECU in any form?
Don't get me wrong, I understand your point, and appreciate that you shared the info, but I think you're on your own in large part with your Xede. If you're trying to get more people interested in it for the sake of a community to work within, I suggest writing up your experience with it - its quirks, its great things, hypothetical tuning scenarios (or real ones) and how the problems were solved via Xede tuning, its lacking areas if any exist, etc.
