Hello, i have an 2013GT86 and because it has
ZA1JA00G in it, i wanted to uprgade for
ZA1JA01G rom. Why? Because i dont have full definition for 00G but found full definition for 01G.
What i did? Downloaded my ZA1JA00G and save to srf, and if i try to save bin it writes something about need to erase some zero data, and the bin file is shorter, so it cant be edited in RR.
When i write the ZA1JA01G file normally without issue, but the ignition was not able to turn off. I was scared, and reflashed it back to ZA1JA00G, and the Car is fine now.
I made some changes to DBW, IGN, AFR and made some progress, gained few HP and Torg. But i want to play more, also with Cams etc...
Did i done something wrong, or how can be the "upgrade" of firmaware done correctly ? For example EVO has Immo code it the rom, so it neads to be transfered in new rom..... but i didnt find anthing like in the GT86/BRZ rom.
Thank you for any usefull info.
