Alright, I'm new to EcuFlash and looking for a little help. I have read through tons and tons of posts and tutorials. Spent hours reading, but i'm not 100% sure and just want some clarification.
So i have a tactrix cable, a 2012 frs, the beta ecu flash installed, and i downloaded all the definition files.
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?
