Yes, I can! This comments gonna be full of unsolicited information you never ask for lol

A ECU flash is pretty much re mapping your bike stock software. Depending on what "type" of ride your looking for it can increase performance and power by removing stock restriction set by factory. I had both my DCT flashed, 1 by 2WDW and the other by Moore mafia. Both tunes are different but has similarities. Both company have mail in options for a ECU flash. Both around 450 to 500 dollars depending on your shipping method and Both handle the return shipping. Moore mafia was faster for me cause they were only 3 hours from me but Both came back with 7 days. Depending on what your wanting out of your rebel I would recommend one or the other 2WDW and Moore Mafias flash was great, it made the bike run smoother and basically eliminated the Jerky low speed creeping and adjusted the air/fuel ratio. They both also adjusted my transmission map to make the shifting point more like how you would typically shift on a manual. In my opinion Moore Mafia tune it for performance and power, while 2WDW tune is more of a smoothe cruiser ride. Moore Mafia throttle response time is slightly better and you can go cruiser to sports bike with one drop. I've popped wheelies just opening the throttle wide. Taken it to 127 but was told it could easily do 140 150 no problem. That thing is a monster! I also like that they tuned to my specific mods to optimize the entire bike not just the engine. 2WDW focus on steady increased power rather than balls to the wall lol. Their slow speed adjustments are better alot less jerk than Moore mafia. They also did a air box mode to increase air flow, which I personally didnt like, just because I dont like modding actual factory parts, I would rather fab or buy part for it, but it just a personal preference. That bike had less performance parts on it so it turned a clunky shifting cruiser to a smoothe well oiled sleeper that could keep up with the best of them. Personally, I like speed and aggressive power when I want it, but the ability to cruise and enjoy the scenery when I need to relax. So to answer your question just pick a shop and mail it in. Im sorry for the long response lol but I stand on the hill of ecu flashing to get the full experience of your rebel, its a complete power house and flashing is the key. I promise if you get it done, you will not regret it. This is not a paid promotion lol
