Will a JDM p13 ECU work with my USDM H22?

yes.... althought it will have fuel and ignition maps made for a slightly higher CR, and it will have the 180km/h speed limiter.

Will it burn too much gas?

So it'll run less timing advance? Might be detrimental for performance if that's the case...

I had a genuine Spoon ECU which is pretty much a chipped JDM ecu and it would not work on my USDM prelude vtec. I am not sure if a JDM stock ecu is any different working wise. I think 4forbidden had a Spoon ecu as well. Too bad, it didn't work.. would be nice to have something not many people have.

keep in mind japan runs on higher octane gas than we do also.

I'll be chipping and tuning my P13 ..
