What are the chances an RX3S ECU will work in my SG400?

Looking to get rid of the flat spot at cruising speeds. Easiest way to do that for Benelli was to buy an ECU that wasn't modified for CARB/EPA requirements. Finding an RE3 ECU on aliexpress is impossible, but the RZ3S used the same engine. What are the chances of it working I wonder...

I would think it would work. See if the part numbers are the same.
