Default Tuning/ecu flashing issues

Hello guys im having some problems with my wrx and im hoping to get some answers because im not sure what to do. First i have a 2003 wrx i just did a swap with a jdm ej205 thats equipped with avcs i had the iap avcs wiring harness all wired up and everything i am using the stock 03 usdm ecu with this jdm setup, the shop where the car is at flashed on a jdm sti rom onto the stock 03 usdm wrx ecu and it brought up a bunch of cel error codes on the screen (written below) they say that cant tune it with all those codes, they also said that the codes make no sense because the car runs ok it just idles a little funky they think there something wrong with the flash. The car runs pretty good starts right up but idles funky the idle goes up and down slowly. (Not sure if this matters but The engine engine i got was off an automatic and its in my manual wrx now)

So the question is if anyone knows what the problem is can that stock ecu with that flash correspond with that engine? Does anyone know any roms that can make this setup work? Just need some suggestions on how i can fix the problem because i cant get the car tuned until it runs and idles good without these codes.

P0037 rear o2 sensor low output (o2 sensor is deleted so this dosent matter)

P0350 ignition coil primary/secondary
P0356 camshaft pos. Sensor bank 1
P0390 camshaft pos. Sensor bank 2
P1307 ocv 1 signal circut malfuntion (short)
P1507 ocv 2 signal circut malfuntion (short)
P1505 idle control malfuntion (fail safe)

Non of these codes seem to be relevant to the car other than it idling weird so please let me know whats wrong!!!
