Thanks to the Orca post earlier I got turned on to RSRs fuel injection. It is a complete system that replaces the stock system using actual manifold pressure as opposed to downloadable maps that Harley is so happy to provide us with (for a price). One of the things I was way let down about when I bought my 2011 FLTRU is that it didn't come with an actual system that automatically made changes for better flowing components. The RSR system claims it isn't a set and forget system and you will need to make adjustments for maximum tunability but they do stress this is something you can do yourself if you have some mechanical ability especially if you add a fuel/air guage. It is expensive and it is bulky (the ecu needs to be mounted in front so it doesn't overheat) but I also think this is something the moco should have provided stock. Our cars and trucks come with this versatility. Why don't our bikes?
