Reset the ecu and drive the car for a few days.
There is no single trick out there to speed up the ECU learning and get the monitors up quickly.
I flashed my truck back to stock and forgot about it and the smog tech asked when it failed why the monitors were not ready.. You need all but two up to pass. My quick thinking brought up that my 3000 watt sound system blew a fuse and killed the battery. He said oh no problem. Go drive it for a few days and said it could be from 50 to 200 miles.

I drove 70 miles and still not ready.. I ended up driving another 150 miles and they came up and I passed. But its all about key cycles, run time and ecu learning working together to get them to come up.

And as far as forcing them with a tune. The new smog computers in Ca scan for OEM map version numbers. They have been watching the tuning world for a few years now and have caught on.
Soon they will be failing people with reflashed ecus and requiring new ECU's that match the oem codes meaning they have not been flashed.

Just flash the car, Take a run to the mountains and by the time you get home it should be good to go the next day. Just make sure you stop a few times to shut the car off and turn it back on with at least 10-15 min between shut off and start up.
