[QUOTE="ajpagosa, post: 1317120, member: 30139"] I ended up using the web form here [URL="https://www.powercommander.com/powercommander/Contact/powercommander_sales_support.aspx"]https://www.powercommander.com/powercommander/Contact/powercommander_sales_support.aspx[/URL] I tried emailing back to the email address from which the guy responded but never heard from him again. I must say after thinking on this for a few days I am disappointed to be told the solution to my difficulties with AT is to essentially turn it off in the area where I do most of my riding. Fortunately the zero map thing seems to be working well and I'm going to try another trick this weekend. Basically taking the OTS DJ map (which is too aggressive and otherwise causes problems), cut all the values in the fuel map in half, and set AT to +/-10%. This will have the benefit of populating the cells with moderate values in the areas I can't seem to fill in, and then restrict AT adjustments to something reasonable that may not get it stuck in a loop on up to one mile elevation changes on a typical ride. And of course allow the AT to target trims in the entire range. One thing that became clear from discussing this with the two DJ reps, the cell values in a given fuel map are actually tenths of a point of AFR. This is never made clear in any DJ literature I've ever read but it makes sense. Eg a value of +10 in a fuel map would take an AFR from 14 to 13. They often say it is a % richer (or leaner) but that never made any sense to me. [/QUOTE]
