not sure if it goes here or electronics.. but
who makes the Mazda ECU?
i am hoping it's not Denso cuz it's uncrackable
best if it's Bosch so we can easily chip it

so is Flashrom easy to crack?
regarding Denso, yes it's crackable, infact, if you have about 2 million, Denso will sell you their program or decryption.
however for Bosch, any vendor could ask for a manual practically. and as long asyou know what you are doing, you can chip /hack/ or whatever right on the ECU(faster). Where as the Denso, you'll have to piggy back another ecu to mask the incoming/outgoing signals (slower)

There are ship upgrades for RX-7s, so I wouldn't expect any problems on the RX-8.
I am curious if it is speed-density or has an air flow sensor though. Anyone know for sure?

Okay. This is what I know so far about the Mazda RX-8 ECU. It's a much faster computer compared to the FD3S & it will be a 32Bit MCU. (FD3S Rx-7 had the 8bit & 16bit MCU's.)
MazdaSpeed will offer an ECM upgrade in Japan... It's worth it, cos not many people out there understand the standards of tunning a rotary sequential injection & the timing table (lead & trail spark) and specially with the new side housing port timing!!!.
A binary hex hacking, or a piggy back hacking will not work as good as a Mazda Speed ECM. Also, the two fly-by-wire throttle body..will be hard to replace with a stand alone. You'll need to pay alot of money to have a proper tuning.
