A couple of months ago I noticed the engine RPM readings on the DC-6B were about 200 RPM higher on engines 3 & 4 than 1 & 2. I use yoke and levers, using one lever for all four engines. I can adjust the levers manually to correspond but as soon as I use the lever again they go out of sequence. I did check the various state.cfg files at C:\Users\[name]\AppData\Roaming\Microsoft\FS9\AIRCRAFT and interestingly some showed significantly different accumulated engine time for 3 & 4 against 1 & 2. I deleted these and let them re-create from fresh but this has not fixed the readings so that wasn't the answer. It may be my imagination but after doing this the variation now seems to be about 300 rpm. Or maybe the difference is just gradually increasing over time. I think the above is logged for FS random failures (which I have "off") but I have a feeling there is some sort of record also kept for CC aircraft. I seem to remember some sort of problem running low on oil years ago but I am darned if I can remember how I fixed it. But I am thinking this may be a similar issue - can somebody please guide me to where this is recorded? Or maybe have experienced this and know another solution?
All DC-6s seem affected, but no other aircraft are that I have noticed.

Carb Ice? Engine Damage?

Do you use the damage module? (Damage displayed on the Notepad.). Perhaps he put some variation in there? Slight variations were pretty common in these old planes.

No to both.
It is always 3 & 4 matching, but different to 1 & 2 which also match - perfectly. 300 rpm is a significant difference, it is impossible to decide the correct setting for each stage of the flight because I can't tell which one is correct. It has been consistent on every flight for several weeks.
I am certain there is something, somewhere, that remembers state of certain things. For instance, if you leave a radio ident on, it is in that position for the next flight (although the switch works back to front).
I might experiment with other gauges, and see what they show, but I don't think that will be the answer.

The thing that remembers the radio idents (for example) is the Flight. If you use the Previous Flight as your default flight, then it might be saved in there. Load the default Cessna at Sea Tac flight, change to the DC-6, and check it then.

Hmmmm. Interesting result but puzzling. Engines 3 & 4 were showing wrong indications, 1 & 2 were correct. Replaced them with alternative gauges and all match now. Need to do a test flight to make sure nothing has been broken in the process but looking as if this is the solution.
Rather odd though. I'm certain they weren't always like that!

PS, I don't use my previous flight as the startup, but thanks for the info on the idents etc. This seems to be "remembered" with many flights in other aircraft in between. I am used to that and it doesn't bother me - as long as you leave it off at the end of the flight it will be right for the next one.

Glad you were able to solve it. Was this in the VC or the 2D cockpit?

I just checked in my FS2004 and each RPM is exactly the same. The gauges used are:
gauge51=Z_DC6KMTG!RPM_1, 1058,682,116,116
gauge52=Z_DC6KMTG!RPM_2, 1180,682,116,116
gauge53=Z_DC6KMTG!RPM_3, 1301,682,116,116
gauge54=Z_DC6KMTG!RPM_4, 1439,682,116,116
They are all dated 5/12/2003 in the Gauges/Z_DC6KMTG folder. They use the standard default (A:General eng rpm:1/2/3/4, RPM) variables, and the non-linearity tables (that determine where the needle points) are the same.

My 6s have the same variation 1&2 show about 200 rpm higher than 3&4.

Mine were the same gauges (I haven't actually deleted them but moved them off-screen).
I can't see that the XML code could be corrupt, so something must be driving them. It's interesting that Mike's discrepancy is the reverse of mine.
Best regards,
John
