Does anyone know of any way to flash the car back to stock or are there any CARB legal NA tunes out there? I’ve been searching for a while and called around and can’t find any. My car I bought when living in AZ has a stage 2 E-85 Ecutek tune and now I want to smog it in CA so I can sell it here but I’m not sure about the tune part. I’m not sure if my car has the stock map still in it somewhere but I don’t know how to access it. The previous owner gave me the Ecutek dongle but I don’t know how to look at the maps loaded on the car or if the license will even be valid for me.

I’ve been told that the “stock” tunes on OFT and such are base maps close to stock but they lack whatever digital watermark that CA now checks for when looking for modified ECU’s.

I’ve called several dealerships and talked to two Toyota techs I personally know and they said they don’t have access to flashing the cars back to stock. No manufacturers that I’m aware of make a CARB legal tune that is for an NA car. The only solution I can come up with is to somehow get a new ECU but I don’t know if the ECU’s are somehow linked to the car that the smog tech would notice somehow?
