Both engines have the same FTH (4500m), max boost (1.35) and WEB (1.45) values. The difference that I found:
- DB601Aa has a higher ramming factor
- DB601Aa has a constant speed propeller

So it is safe to state that the DB601 family is not modelled correctly regarding FTHs and max MAPs and the engine of any Emil in the sim is a mix of both Aa and A-1.
