Something i have noticed based on reading the aircrafts manuals and seeing real life videos on the spitfire, the issue regards the mixture controll lever as it is currently it is inccorect, currently to start the engine you must, set the fuel cock, build fuel pressure using either method, prime the engine, open the covers press both at the same time and once the engine begins to splutter or "catch" move the mixture into the "RUN" position from "IDLE CUT-OFF" referencing "Air Ministy Air Publication 1565J, p&l-P.N. September 1946 Pilots notes" (this covers the merlin 61,63,66,70 and 266) it should be done as follows, (PRE-START) set fuel cock ON Ignition (magnitos) switches OFF Throttle 1/2 in.-1in. open RPM lever fully forward Mixture lever (Marked correctly as Idle cut-off lever) Fully Aft Supercharger Auto Carburettor air intake filter control Filter in operation (START) Switch ON the main tanks booster pump for 30 secconds (this is done as both the wobbly fuel pump and booster are mutually exclusive and it is used instead of the wobbly hand pump) Then switch it off (at this point the low fuel pressure light should extinguish) and set the mixture (idle cut-off lever) to the forward RUN position Prime the engine as required based on the outside temps switch on the ignition (magnitos) and press the starter and booster coil pushbuttons when the engine fires release the starter button; keep the booster could button depressed until the engine is running smoothly the issue is, that this is not possible in DCS you can only start the engine with the mixture aft then wait untill the engine "catches" and move the mixture to run, as you can see in the manual this is inccorect you can also find videos for the real thing starting up in the manner described in the manual and not how it works in DCS, this is something that has bugged me for a long time, and i could not find a report on it so i thought id make one. I own a phisical copy of this manual can have a digital vertion i can send if you need it both are identical i can also provide a video if you wish regards minty

EDIT/ADD: -Boost gauge tricky to read. Further down thread (see image) I found "true non bugged" idle boost ca -6.2. -I stupidly wrote zero (0) when meaning lowest idle boost. Edited to -6.2 in text (red). At no point during testing (all tests, all posts) did it actually show zero (0). Except engine off obviously. -Spitfire. Bugged (idle) high boost shifts between -3 or -4 depending HOTAS RPM level max/min. Might jump straight to post #6 (first with image). Previous posts I grasped less what's happening. Also, probably not intermittent (one thing I didn't grasp). I crashed Spitfire, did Quit -> Fly again. Suddenly Spitfire rolled on Spawn Rwy. Spitfire & P-51 both increase idle <1000 ~1500, Boost goes to -4 Spitfire instead of idle 0 -6.2. Seen once P-51, Spitfire all the time. Not tried others. When observed with Thrustmasters own software "Device Analyzer". All buttons work, analog hit correct endpoints (0-16383 for example). When plugging in the throttle the boost & rpm increases. What can this be? Throttle otherwise seems to work as it should, ie I can increase & decrease, just starting from boost -4 instead of zero -6.2 (Spitfire). Calibration? This has never happened before, bought 2018, so ie five years old, so I fear something more problematic is afoot.

Multiplayer, so no meaningful track. Don't know how to recreate so therefore not a bug report. 1) Oil pressure Generally oil pressure is at 120 psi or over unless boost & rpm set low. Recommended is 60-120. I find it a bit off that oil press is almost always at 120 or more. Specific case now. Flew 100 nm abouts. Boost 7, rpm 2850. I noted how the oil pressure was stuck at upper range (150). Why? Wasn't stressing engine at all. -3'C degree Aerobatics Online Server. Landed, engine quit. Figure it was the high oil press was the cause. I've noted typically oil pressure drops with radiator closed (switch forward off). Flipping switch rearwards (radiator auto, opening), oil pressure always goes up even more. 2) I long noted occasional weirdness with the starter. Specifically sometimes it refuses to turn over after repair and adding ground power does nothing. Brand new weirdness (same flight as above). Attempting to start after engine quit, it didn't, as expected, assuming engine seized. But, further, volt meter dropped and stayed dropped after releasing starter button. Then I could watch the voltage dropping as if something (starter engine?) just drew tons of current. Immediately after repair finished, prop turned over as if starter engine was still stuck. Watching the voltmeter I clicked the starter button and prop stopped turning and voltage shot up a bit again (as if "unsticking" the starter button). Attempting to start to start after repair. Voltmeter at 10V (which I remember is to low, needs 13-15V). Prop turns over slowly. Add ground power and once again confirm ground power does not work. With ground power, obviously prop should spin over fast enough to start. I even believe starting by battery was the exception in real life. Add a link to my old thread when I find it. One thread (commented but not started by me) on no working ground power. I observed some weird volt flickering, which i note is commented on in linked thread also.

Quoting old thread: Ground Power is for starter, what I always assumed, makes perfect sense. But ... I've noticed many times, engine refuse to turn over, battery seems low, after repairs. Connecting Ground Power doesn't help. So I did a simple experiment with P-51 and with Spitfire (Summer +20'C). 1) Spawn "Takeoff from runway" (This assured engine temp/oil pressure was up, no damaging engine by turning over cold) 2) Shut off magnetos (engine stops) 3) Spun the starter until battery drained (prop stopped moving) 4) Attached Ground Power and attempted to start. P-51 started (as it should). Spitfire prop didn't turn over at all (voltmeter showed 5V (down from initial 14/15V), whatever that means *1) If Ground Power is for starting, which again makes perfect sense, then this is a simple well defined bug. Ground Power should power the starter in an undamaged aeroplane. *1) Would ground power really bypass the voltmeter? If it does, be that as it may, the important point here is that ground power doesn't power the starter.
