I have a 2013 FR-S with a tuned ECU (I'll explain). My smog is coming due and I'm concerned that I will fail smog because the ECU is supposedly tuned to remove the well-documented torque. I say supposedly because it came with an ECU flasher and I was told the work had been done. Can I reflash it back to the original? Will the smog tester know or am I ok reflashing it back to the original specs?
