You don't install a firmware for a specific board or MCU type. The firmware release is the same for all. You select your board type and MCU type in tunerstudio. Please see the wiki linked to in above reply

Thank's everyone reply.

Maybe I'm gonna be ok.

I tryed installe one older speedyloader(202204).
Then Tunerstudio muchi with speeduino v0.4.3c.

I guess speeduino v0.4.3c needs sumething fit file.

Everyone good luck!
