I find it extremely unrealistic to dart around with the pedal to the metal all the time a la 1946. In manual mode, I tweak the rpm to around 9:30-10:10 to maintain a decent cruising speed, but the auto simply assumes I want the prop pitch backed off all the way, regardless of my planes attitude (dive or climb). Is that the way it worked historically? I know this isn't as sophisticated as the later Kommo systems.

As I said in my post if you want some different ATA/RPM combo than Auto gives you then drop in to MANUAL and go for it. I dont know exact values for the DB601 but these are the values the DB605 uses ... this comes from a known DB605 experten (Schwarzeman)
2100/1.05 900PS Economic cruise
2300/1.15 1075PS Max continuous
2600/1.3 1310PS 30Min Climb and combat
2800/1.42 1475PS 3Min Emergency
Obviously differrent values to the DB601 but it will give you an idea of the sort of relationships between ATA and RPM in AUTO. Remember AUTO RPM is determined by throttle lever position NOT ATA. Obviously below FTH then ATA is also determined directly by throttle lever position so in effect they are the same.
The numbers I have seen in CLOD DB601 (below FTH) for the AUTO ATA/RPM relationship are:
1700/1.00
1800/1.1
1.2/1900
1.25/1950
1.3/2050
1.35/2300
1.42/2350
We know the min governed RPM on the DB605 is 2000RPM. This effectively the Min RPM pitch stop. I suspect the DB601 in real life is the same (yet to confirm). If this is the case then it does suggest the CLOD ATA/RPM relationships for 1.0 to 1.2 are a bit low. If some one has documented DB601 values it would help getting this tweeked.
The bug on spawn in the E1-E3 and on the E4 when you select MANUAL of the prop winding back is a known bug and hopefully will be addressed. The fix is a quick blip to stop the windback. Re set 12:00 and then you are good to go. I do this this every engine start. I take off in MANUAL (12:00) I select AUTO once I get airborne. Using this technique I have never seen the prop slowly winding back to 8:30 and getting stuck.
