I'm certainly not saying it's impossible or even unlikely! I was just thinking from a perspective of map sharing or "common" maps for similar sets of mods, which seems to be the trend in the WRX community, moreso than individuals hand-mapping their own vehicles.

I had a very nice, consistent MAP-based program running on my Integra turbo via AEM's programmable EMS, but I surely wouldn't have expected it to run even decently on another car with anything but my exact set of equipment (in fact, I swapped a friend's map from the same engine, same turbo, but different intercooler, and it was WAY off according to mr. wideband!). A speed/density system will work just fine on a stock vehicle or any vehicle that has the benefit of a skilled tuner and sufficient time on a dyno or at least a road under controlled circumstances.
