That's what I thought to do, but sadly used ones on eBay cost as much as a new one. Still iffy about orange virus, it seems like they basically just fine tune the tactrix tune in a lot of ways. I guess that's just charging for the putting in the time to do so. But I would think all stock CX-5s would have a pretty identical baseline and that you could just go from there for a build based on installed mods and whatnot.
