ECMLINK V3 SD Elavation Testing NO PROBLEMS Tune stays good

SD (Map sensor based) Has been out for almost 2 years now on V3 and I always get the question since the MAF and Baro are gone that the tune will will change when going up or down in Elevation.  While I had no reports in the 30+cars I have done on SD with Tune changing problems we wanted to find our for our self.  So the Fammily and I took a little trip to Timberline lodge on MT Hood with a few pulls along the way noting crazy since the Family was with me.  I was happy to see that the tune stayed dead on with 5000ft in elevation change and about a 20deg air temp change. 

Here is a little YouTube Video I made of it.
