I heard that Flashpro will not pass smog test in California even with the base map.

Any workaround or solutions?

If you are in CA and flashed already, what’s your plan?

You can just flash to stock

Yes, you can flash back to stock and reflash to your tune, but why would you need to smog a new car? In California if you purchased a brand new car you are not subject to a smog check every 2 years like older cars. My car was purchased new in 2023, I don't need a smog check until 2031, that's even if I keep it for that long.

Can I flash it back to stock myself or have to pay a shop to do it?

once I passed smog do I have to pay again to get flashed?
Yes, no, and no. Very simple to flash back to stock or between maps.

Yes on no smog for a number of years. Some people hesitate flashing a new car in case warranty issues pop up, ECU had a flash counter and it could void related warranty.

Case in point GR Corolla.

Catbacks are ok for smog, intakes aren't. Swap that back too if you mod.

How does California inspect for smog? Physical validation of equipment? Sniffer test?

In Texas, they plug in the OBD2 and ensure both O2 sensors and the EVAP are listed as "READY"—you can have an O2 or EVAP listed as "NOT READY" but not both. If the ECU reports OK, we can have whatever on the car. I ran a high-flow 100-cell catalytic converter in my '17 EX that would occasionally throw "NOT READY" on the 2nd O2 sensor, but it would clear up long enough for inspection. They'd never know it was tuned unless sensors were turned off.

In cali I believe everything has to be check ready and sniffer.
