Does the TTS offer enough of a fuel ratio range to really make a difference with cooling? I like the Power Commander (on paper) because the closed loop areas of the map can be adjusted more. I do like the Idea of the TTS, just wish it used wide band sensors and had greater range. The fact that it allows writing a map to the stock ECM is enticing. I just can't decide.
Cooling down the late model bikes is the the common goal. Just adding fuel alone wont accomplish this. Improving overall efficiency with proper intake and exhaust
improvements combined with appropriate air fuel ratios based on engine load will get the results everyone is after. Making more power with the same amount of
fuel is the key to cooler temps. As mentioned, the richest close loop setting on the 2010 Lambda bikes with the TTS is 14.34. This is a hell of lot richer than the stock bikes
that float right at 15.0 AFR. A good touring bike gets good fuel milage. You want to be the guy in the group pointing at his tank after two hours? Set your cruise AFR richer
than 14.0 and you will be that guy. These late model bikes have 02 sensors, electric throttles, adaptive knock control, adaptive fuel and on and on.
The TTS software allows simple access into one of the MC industry's most sophisticated EFI systems ever made. The one that you already have.
You want 13.5 AFR at 4000 RPM at 60 KPA and up? Go in and set it. Tired of that speedo reading fast? Fix it. Electric throttle lag? Click click, gone.
You don't need Wide band sensors to control your stock ECM. You just need access.
