Will a 2021 or 2020 ecu work on a 2019?

So my 2019 has the bog and loading up issues that some others have had. Saw that the re flash made it worse for some, so was thinking of just trying another ecu so if it got worse I can put the original back on without losing much ride time. Plus, I can't seem to find a dealer that knows anything about the re flash anyway. Any info is appreciated. Thanks.

Probably, but another thing is new "not oem" spark plug wires from the coils, and getting your injectors checked by a injector servicing shop.
Even with low mileage there can be big differences of flow thru powersports injectors, or they stick up, etc.
Good luck.

Make sure both sleds have the same fuel injector color code yellow, blue or red and oil pumps codes match there is different flow rates and the ecm tag will tell you that info
