If your scoot (ECM) ever takes a dump and you don't have the tune your screwed.............. that's about all I can say about that.
FWIW: I agree with this post. How are you expected to restore your map that you paid for if you have a problem without a copy??? you may be far away on a trip when an event happens to cause you to have to "reload".
Also, it is important for you to know that you can't view the current map in your bike with the new Supertuner either just as you couldn't with the old SERT. This is a big disadvantage for the SSERT in my assessment because you may want to make small incremental adjustments to your existing maps. The only advantage is the new data logger component BUT you need to have the bungs and the computer with your existing map in it to "upload" the logged/suggested changes into so you can make them and save the map--to your computer and to a CD in case you need it.
If you have been following Steve's TT Master Tune postings then you will now see the reason his product may be a better solution. (please read and make your own personal decision)
I for one would like to be able to "view" the map in my bike and upload it into my computer and save it in its native form.
I am hoping that HD will see the error in their ways and release a modification/enhancement that fixes this critical issue.
