I was talking about the 1st generation Yamaha flash being non-reversible
The only thing I dislike about the original Map (other than engine braking which I've already reduced) is the noticable dip in low end power which is because of Yamaha having to comply with the EU emissions test.
Well, in my case the DNA filter i put yesterday has soften the "snatchyness" in STD & A modes about 50% and the dip that you mentioned around 3.500-4000 rpm is now not noticeable.
I think that happened from the torque increasement.
My bike has now 8.750 km and is completely stock... i haven't touch even the CO settings and i'm waiting to do it at 10.000km service on the fuel injection synchronization...
Yesterday it was so early to understand if the filter helps on snatchiness reduce, but today -after some tests on A & STD- i must say that there isn't neccesary to do the remap.
After i rode MT-07, the mechanic told me that the power in low rpm -after the remap update- wiill be similar to 07.
MT-07 has no snatchiness, no power, lot of vibrations and reminds me the old Honda XLS185... easy to ride but no fun.
Sorry mates... but i feel lucky.
Of course IF i do a test ride and like the updated demo-bike i'll take the same way as many mates from our forum.
But my MT-09 don't really bothers me as it is... though i suggest to anyone first to try a dna filter.
