Can dealers re-program ECM?
I bought my 2006 street glide used from a dealer. When I got it it already had a stage 1 air cleaner on it. Well I added pipes the bike ran great but I since installed larger baffles and thought maybe now I should install a power commander well when I installed the PC the bike ran VERY rich so I unhooked the PC and called for a different map they (PC) give me a different map to try so I uploaded that map and the bike still ran VERY rich. So I removed the PC the bike is back running great. Which it got me thinking maybe when the air cleaner was installed they re-programed the ECM then when I added the PC it made the bike twice as rich? Also bolted to the ECM with a nice bracket there is a small box that has a couple of wires that plugs into the main harness. Nowhere in the service manual can I find out what this box is. Does anyone have a clue to what this box could be?

I can tell you two things for sure:
1) I own a 2006 Street Glide and that thing is NOT stock, so you won't find it in the service manual.
2) The company referenced on the sticker DOES manufacture aftermarket electronics for motorcycles and ATV's including EFI modules.
I suspect someone had it installed when they did the stage one upgrades. Can you unplug it and run the map Fuel Moto supplied to begin with?
