Ok, I have been studying the different tuning devices for the 2010 Street Glides when doing a simple stage 1. I have decided against a Piggy Back unit. I will be using a TTS Mastertune. However, I'm still confused as to where each device does its magic, and if you need more than one device to keep temps down and richen things up? For example, I read about a Terry Componants plug and play for closed loop. In the instructions it says it works well with the Screaming Eagle race Tuner? What? Doesn't the Race Tuner Modify the entire ECU just like the Master Tune? Does it only richen things up above 2000RPM out side of the closed loop mode. Man, I'm confused. If there is anybody that can explain this simply, I would be forever grateful. Won't the TTS do it all? Thanks for a crash course in closed verses open loop, and what is really needed to cool her off and help her run better!

 

The TTS will do it all. It will allow you to adjust both open and closed loop areas of the bike. NOTHING else is needed except for a dyno tune.

 

Thanks. I am pretty handy with the wrenches so it drives me a little crazy when I don't have all of the details on systems such as the later EFI. I know only enough about it to get myself in trouble.
