We just got 16x14 a few years ago, and it was a "real pain in the ass" to have 2 of everything(firmwares, folders in MT),
as the old-schoolers had a "death grip" on their beloved 12x12!
I have cars running 40+ psi boost at 8000+ rpm, and I'm fine with 16x14.
Especially if the number of set points isn't adjustable.
(With other ECU brands I might use 20 or so RPM set points, but I wouldn't want to have to do that on all cars)
I much prefer the firmware that is released work properly, with less "bugs" and annoyances, and more documentation.
