I've gone back in the ratnet forums and have read reference to the 12 minute tune a number of times, and I noticed it came up in this thread.
would someone explain that process to me?
The same thing can be done with the Triumph tool and tuneboy. Basically you are forcing adaptions. The ECU saves fuel trims over time. After you make an intake or exhaust change resetting the adaptions allows the ECU to learn the new required trims faster. You are basically wiping the chalkboard clean and starting over.
Kmutt - if the bike is running fine, no need to do a 12 minute tune.
