Did The 12min Tune & WOW!

2011 Storm 3,500 miles what a difference! If you haven't done it try it, tremendous difference in throttle response the bike just hauls ass now.

I've tried the 12 minute tune a couple of times, with no noticeable results. My motor has always 'surged' a bit when idling, but I figured it was normal.

One time I did the tune and I let it run for around 14 minutes, the other time about 12 and a half minutes. Both times I stopped the engine, and then restarted it within a few minutes to ride it ... no change that I could tell.

Last night I decided to try it again ... exactly 12 minutes after the fan came on I shut the engine off, closed the garage and headed to bed.

This morning it started first push of the starter. (its been taking a couple of pushes lately when cold) ... and man, it rides smoother and more powerful than ever! A real, noticeable difference. The 12 minute tune seems to have finally worked for me.

Maybe it was timing it exactly to 12 minutes ... maybe it was letting it cool down afterwards this time ... I'm not sure.

What if there were no hypothetical questions?

Lots of threads on this...

Start your bike from cold.
Do NOT touch the throttle at any point.
Let it run until you hear the fan come on.
When the fan starts, begin the timer.
After 12 minutes turn the bike off.

It triggers an adaption cycle so the bike can recalibrate all its sensors and settings according to the current environment (air pressure, temperature, humidity, fuel/air mix etc).

What if there were no hypothetical questions?

I asked my dealer if they had done the 12MT when they installed a new map on my bike the other day. The tech said they almost always do a 12MT whenever they do anything major to a bike. He then explained how they do it: start the bike without touching the throtle, wait until the fan comes on, then wait until the fan goes off and turn off the bike - that's it.
Anybody hear of this and does it work?

Yes its nice to find a short cut! BUt this could be why so many people have found it nessasary to do the 12min tune themselves after having things done at the dealer.

maybe thats the way the dealers do it using the triumph tool as they call it. Triumph's "tuneecu" if you will. tuneecu also has a fast adaption but i don't think it works from what i've read.

12 minutes is probably the maximum time that it takes for the bike to acclimate. Oldgreybull's dealer has probably figured out the minimum time needed to do the tune and saves the excess time and gas.
