Revert to the stock map and lock the ecu. This will give you the correct checksum. Then do the drive test from my link to reset the monitors. You can use a bluetooth OBDII adapter and an app to check them prior to going to smog. Assuming they all set, you pass smog.
A generic app may not tell you which monitors your car actually has. My link has the ones present on my car, which should be the same for yours.
