You can’t read or do anything to the map in the ECU. You have to read in a map into the app, like the Penner tune for the USA GT, uncheck the speed limit under parameters, then download the map to the ECU. I don’t think you will be able to uncheck the speed limit box unless you pay more $$, according to Alain Fontaine (the app developer). If you can uncheck it, it may not “take”.Yes, I purchased the app, registered the bike, and found the option to remove the speed limiter on it. What I am unsure of is how it actually works when I go through with it. Will it change the existing map on the bike? I want to put the Penner map on, but haven't done it yet. I want to make sure I don't spend the money to remove the speed limiter and then flash with the Penner map and undo what I spent the money on. I will contact the developer. Thanks!
