This seems like a stupid question even to me, i think i already know the answer to it, i want to re-flash with a OTS Map, do i need to use the same ecu? Say i have ZA1JA01C.bin do I have to use a modified ZA1JA01C.bin or can i used a ZA1JB01C.bin already tuned? And would I be able to go back to the stock bin? It seems like i can but it seems like no one says yes specifically. More so, could i flash any FRS Rom on to my FRS as long as it is MT and US?

WARNING !!! Tectrix/ecuflash will let you flash any ROM to your car regardless of if is suitable or correct. It will READ any ROM but it will not WRITE one without a corresponding definition file.
It has no safeguards unlike the Open Flash Tablet which checks ROM type for you and is much more user friendly.
You will also need to install the Updated 32bitbase file for ECUflash else this may end in tears.
Assuming you have
1. Correct version of Ecuflash BRZ Beta
2. correct definition files for your ROM type and the alternate ROM type you want to flash
3. Correct 32Bitbase file for BRZ
4. update the firmware in you tactrix by going to the licensing tab in Ecuflash first.
Read you stock ROM first and save it as SRF and BIN to save as bin you need correct def files. you cannot write a ROM without matching Def files.
Open the ROM in ecuflash and make sure the tables look ok and readable.
Try writing you stock BIN ROM file first then move onto writing an alternate ROM.
I believe A01C and B01C ROM are comparable but you will need def files for both to be able to read and save you A01C ROM and write the b01C ROM.
Understand what you are doing and have a backup plan if it goes south.
