WM1Aᶻ revision B
To keep it short, this is WM1Aᶻ, but with improved resolution.
As I really like how it sounds, I'm also sharing it here.
Depending on each person's preferences, it may not sound
better than the original WM1Aᶻ. As with the ZTAZ1, see this
as a different experience, having WM1Aᶻ as the base. Some
people may like this one more, some may not.
You can find it
here (click).
Same story goes here too: based on J region, and on the 3.02
firmware. If you decide to give it a try, feedback would be appreciated.
Also, if you used other tunings before, it's recommended that you
first flash back to stock, and then apply any other tunings. Stock
3.02 is available here (click).
While this can also be applied to all WM1Z variants, it was originally
intended for the WM1A.
Thanks again
@aceedburn for giving it a listen!
I might soon have to make a single post for all these, to link them all
in my signature, as you can't put more than five links in there
