Hello
I want to see if anyone can help me to re-program the ECU remotely to make it back to Stock ? Trying to pass smog in California and it showing software is modified. Car is 2016 Scion FR-S

you probably want to provide more details if you can. do you know what was used to flash your ECU? the process might be different depending on what solution was used. here is a topic using ecutek https://www.ft86club.com/forums/show....php?p=3535037

I replied because I have to do the same thing but in colorado. I have a 13 FRS with catless header/midpipe DT Flex fuel (non canbus). and have to revert all of that, flash a stock tune, revert to stock. then I can pass emissions. also a neat feature of returning to stock is I LOSE my ecutek license and have to buy a new one apparently. at this point I wonder if its easier to buy an ecu get it right and just switch ECUs with the other hardware every year.
