9.JG27 DavidRed Posted December 2, 2014 Share Posted December 2, 2014 ok, im now flying the 109 for a couple of hours already with my friends.and damn it, im the only one suffering from a strange problem...right after take off my fuel pressure goes down and the engine starts stuttering... start up procedure is ok though, checked several times and compared with my friends...this is only happening when i do a cold start...from the instant action take off mission this doesnt happen.also when im starting a mission with an air spawn i dont have trouble either...:mad: really frustrating as i just dont know what it is.

Mobius_cz Posted December 2, 2014 Share Posted December 2, 2014 Same here... I am trying to investigate what is it but it doesn't seem like a bug to me, because it looks like it is modeled not just an error.

Virun Posted December 2, 2014 Share Posted December 2, 2014 The same. This happens only at high RPM. Активно летаю на: F/A-18 | F-16 | Су-27 | МиГ-21бис Link to comment Share on other sites More sharing options...

9.JG27 DavidRed Posted December 2, 2014 Author Share Posted December 2, 2014 ok we came to a conclusion in this...it seems to be connected to cold start ups...otherwise this doesnt seem to happen...then as soon as you go full throttle you will lose fuel pressure, and once you throttle back, it will be back up...all my friends didnt notice as they never took off with full throttle it seems. spawning with running engine, in the take off mission seems no problem though, and also spawning mid air is no problem.

ED Team NineLine Posted December 2, 2014 ED Team Share Posted December 2, 2014 Are you priming enough at start up? Forum Rules • My YouTube • My Discord - NineLine#0440• **How to Report a Bug** Link to comment Share on other sites More sharing options...
Virun Posted December 2, 2014 Share Posted December 2, 2014 So, at first I thought the issue was about MW50 switch, like we all forget to switch it on the ground and then fill the fuel system with methanol. But I tested this and it's not the cause of the problem. It really looks like about P1+P2 pump switch not working! For example: 1) I started mission in the air and everything works prefect at 1.8ATA no matter how long I fly in this regime. 2) Then I switch to P2 pump only 3) Fuel pressure starts to fall as it should 4) Then I switch back to P1+P2 pumps regime 5) But fuel pressure not recovering to normal at 1.8Ata! It continues to fall just like it did if I would start a mission with cold start. So basically it looks like P1+P2 not working if it's switched by the player.

Eldur Posted December 3, 2014 Share Posted December 3, 2014 Fuel pressure needle starting to vibrate and go down is happening if you fly at full throttle which is 1.8ata of manifold pressure, occurs after like 30 seconds, didn't stop watch the exact time. As soon, as you decrease the throttle and manifold pressure jumps down to 1.42ata or less, the fuel pressure rises again and stops vibrating as soon as it's full up again. So this definately has something to do with the fuel injection at given power settings. I saved a track of my first flight that I could take off "somehow" without breaking my plane :megalol: - and noticed this already and had a passage in that flight where I watch the needle go down and up according to MP change, that should be enough track proof. My flying skills at DCS WWII suck, but this is evident nevertheless. Link to comment Share on other sites More sharing options...
9.JG27 DavidRed Posted December 3, 2014 Author Share Posted December 3, 2014 Are you priming enough at start up? yes, thats not the issue. also after my friends went "full throttle" as well, they all could replicate the issue.but as i said, if you spawn in the air, or already on runway with a running engine this problem doesnt occur.

ED Team NineLine Posted December 3, 2014 ED Team Share Posted December 3, 2014 Ok guys I will try and reproduce in the tester version and report if needed, thanks!

9.JG27 DavidRed Posted December 3, 2014 Author Share Posted December 3, 2014 cool...can you give us feedback on this, whether you could reproduce it?whether its beeing looked at by the devs?thx in advance Link to comment Share on other sites More sharing options...
ED Team NineLine Posted December 3, 2014 ED Team Share Posted December 3, 2014 Of course, I will tag the thread reported if I need to report, if its fine in the test versions I will let you know Forum Rules • My YouTube • My Discord - NineLine#0440• **How to Report a Bug** Link to comment Share on other sites More sharing options...
9.JG27 DavidRed Posted December 3, 2014 Author Share Posted December 3, 2014 ok, i dont know why, but today im getting that problem also in the dogfight mission when spawning in the air!that bug seems to get worse!fuelpressure.trk Link to comment Share on other sites More sharing options...

9.JG27 DavidRed Posted December 3, 2014 Author Share Posted December 3, 2014 yeah i know, Sith already reported it..still i thought maybe its helpfull to say that it happens when spawning in the air as well...cant hurt at least to mention it...though its strange.it happened to me 3times in a row that pretty much immediately after spawning mid air against the p51 the fuel pressure went down...after restarting the game though, and loading the mission again, it was fine again....

iFoxRomeo Posted December 3, 2014 Share Posted December 3, 2014 (edited) When I activate the booster pumps with the mouse, then I have these problems as well. BUT! Activating via keyboard solves the problem.

ED Team NineLine Posted December 3, 2014 ED Team Share Posted December 3, 2014 This is now fixed internally so I would hope it would be released in the next update, or maybe when this goes from Open Beta to live.

Some other things will effect fuel pressure as well, going inverted, negative g's... so keep mindful of that, lets see how it acts once this fix comes down and go from there.
