More than once I thought about trying to use Austro Wizard software on a laptop to upload DA62 AE330 (E4P-C) ECU software into my AE300 (E4-C) engines back when I owned a DA42-VI. I'm not sure if the Wizard software does hardware configuration validity checking as part of its handshake with the ECUs to preclude this, but it would otherwise take only about 15 minutes of work.
The only real difference I can find between the 2 engines is software, so in theory a different software load would increase AE300 sea-level performance from 168 hp to 180 hp by telling the turbocharger waste gate to increase turbo boost pressure. But there's at least one BIG difference that would make this change impractical: the DA62 propeller is about 1 inch greater in diameter than the identical-looking MT prop on the DA42-VI. Since ECUs also control the prop governor, the difference in propeller sizes might cause an engine malfunction if trying to run DA62 engine software in a DA42-VI.
Realistically for Diamond to make a change to current AE300 software for E4-A engines in DA40 NGs, E4-B engines in DA42 NGs, or for E4-C engines in DA42-VIs would require considerable work and expense. In particular, Diamond would have to re-certify and flight test these aircraft with more horsepower to establish new V-speeds, performance charts, etc.
