Default Passing emissions w/ a jdm motor on a usdm ecu

I have a jdm v8 motor swapped in w/ the corresponding ecu, and I was wondering what my options were come emission times. It's pretty lenient over here, no intense visual inspections like cali, I'm just worried about the readiness monitors passing the obd check. I have my original usdm ecu, which I was planning on throwing back in when the time comes. I figured it would throw a code for the lack of an evap solenoid and maybe a couple other things, but I can disable them through ecuflash. So the question is, if I use the force pass readiness monitor feature on ecuflash will it still pass the evap readiness monitor considering there physically wont be one on the car (remember I'll be disabling the code for it as well)? Any input is greatly appreciated, I dont wanna have to swap out my mani come emission time for a stupid solenoid.

you have to disable all tgv codes in the usdm ecu. While at it you should disable all the codes associated with the catalytic converters. then you force the readiness pass. it worked for me

not sure what you mean about the evap thingy, i didn't have to fiddle with it i guess because i just disabled what i mentioned above and it passed like a charm.
