Throttle question for Twin Pilots

I have 2 Saitek throttle quadrants side by side.

I start this declaring I'm no twin pilot... nor pilot at all, if not of simulators, sadly, for matter of money... :( ...but it's quite a renown fact that IRL there is no engine that is perfectly 100% similar to another. Between two very same model of engine, built in the same factory, in about the same timeframe, and kept efficient in the very same manner, you'll find ALWAYS operational differences, and these differences translates in very rarely having throttle axis lined up, like so very often happens in the various sims.

And if you keep in mind that prop governors and carburettors are similarly NOT 100% similar one to the other of the same kind, just like engines, props and mixture controls follow the same rule.

There's no really "acceptable differences" written on paper that I know of (and if there is, it is expected it should change between a plane and another). If an engine begins straying too much from the expected parameters, it simply means it needs to overhauled, but unless you use some complex payware with very complex damage modules that work per engine, I don't think you need to worry about this.

The various simulators for PC (all of them) give often a very unrealistic response to single axis throttle commanding multiple engines, like so often happens when using a joystick with a small throttle controller like mine, but being non professional softwares, consistency is often preferred over perfect simulation (and it makes the coding easier too). Consistency that IRL rarely, if ever happens.

Of course in YOUR case, you may fall straight into the rule that no throttle control is perfectly 100% similar to another of the same kind (yes, the rule is valid for PC throttles too :P), and using two different throttle levers to command an engine each, you have surely a more realistic response than... than me, for example. I wouldn't really begrudge that, was I in your shoes. ;)

There is no such a thing as overkill. Only unworthy targets.

I frequently do use complex payware with individual engine modelling.

In Real Life every plane engine comes with a servicing history of every part it is composed of. Not only that, but a flight crew taking command of a plane WOULD have received some sort of warning from the crew going off duty about an engine misbehaving. It is quite simple, with this knowledge to glean where the fault of the system is more liable to be. :-/

In the sims, usually you don't have a servicing history of your plane, or even only the engines... every time you start they are brand new, and similarly, you do not have a crew going off duty to tell you if the plane you're about to take up in the air has one or more faults. :P

Limitations of the system. We all have to accept them. Even your engineer, cute as it is, must make due with not having opposable thumbs. ;) :D

I'm actually not seeing it is a limitation.

In every twin I've flown, the throttles or power levers have not been perfectlly lined up while the engines are at the same power setting.

the levers might be in-line at 21", but not 25" of manifold-pressure

Thank you, gentlemen.
