Nealius Posted April 18, 2021 Share Posted April 18, 2021 Above 14~15,000ft with the supercharger engaged, the sound and boost needle will spazz out if I push it past +10. If I push it to +11, the needle will oscillate between +10 and +13 or so, with the supercharger sound cutting in and out. User error on my part?

User error on my part? looks like some bug making supercharger going back na forth between n1st and 2nd gear ? Do you have track ?

Nealius Posted April 18, 2021 Author Share Posted April 18, 2021 Long track I seem to recall this happening a while back last I played the Big Show. Once I got higher in altitude the oscillations would stop, but recently I haven't gone above 18,000ft or so. Link to comment Share on other sites More sharing options...
Hunter Joker Posted April 18, 2021 Share Posted April 18, 2021 Confirmed, I also noticed the new bug. Inviato dal mio BLA-L09 utilizzando Tapatalk 1 https://www.youtube.com/user/garaganotube Link to comment Share on other sites More sharing options...
grafspee Posted April 18, 2021 Share Posted April 18, 2021 (edited) Yes, easy to reproduce. I got boost fluctuating at take off 12lbs 3000 rpm, as well as above 14k ft after 2nd speed was engaged. Track included. Beside, anyone noticed that sound level is much higher when you close canopy? broken boost regulator.trk Edited April 18, 2021 by grafspee System specs: I7 14700KF, Gigabyte Z690 Aorus Elite, 64GB DDR4 3600MHz, Gigabyte RTX 4090,Win 11, 48" OLED LG TV + 42" LG LED monitor Link to comment Share on other sites More sharing options...
Magic Zach Posted April 20, 2021 Share Posted April 20, 2021 I noticed this happening as well, same altitude roughly. It starts at around 15,000ft ish at the default atmosphere temp, and the needle keeps jumping around until about 17,000, where it stops jumping and steadies itself out as I continue to climb. It starts again as I start to drop altitude. Only seems to do this, like the OP said, if I push the boost past +10 Hardware: T-50 Mongoose, VKB STECS, Saitek 3 Throttle Quadrant, Homemade 32-function Leo Bodnar Button Box, MFG Crosswind Pedals Oculus Rift S System Specs: MSI MPG X570 GAMING PLUS, RTX 3090, Ryzen 7 5800X3D, 32GB DDR4-3200, Samsung 860 EVO, Samsung 970 EVO 250GB Modules: AH-64D, Ka-50, Mi-8MTV2, F-16C, F-15E, F/A-18C, F-14B, F-5E, P-51D, Spitfire Mk LF Mk.

122sqn Bruv Posted April 27, 2021 Share Posted April 27, 2021 spazzing out is a good way to describe it. Link to comment Share on other sites More sharing options...
Emacs Posted May 7, 2021 Share Posted May 7, 2021 Switching the fuel pump on helped me in such cases. Fuel pump being the foremost of the hard to see three switches on the left side. The fuel pump switch is practically under and hidden by the rudder trim. And I think my new callsign will be „Spazzing“ Spazzing, out 2 Link to comment Share on other sites More sharing options...

Art-J Posted May 7, 2021 Share Posted May 7, 2021 @Emacs - we're duscussing other issue here. Engine cutting out because of fuel pressure loss without booster pump is one thing, but in this case, we're dealing with mysterious manifold pressure fluctuations, which just were not there in previous versions of the game. 1 i7 9700K @ stock speed, single GTX1070, 32 gigs of RAM, TH Warthog, MFG Crosswind, Win10.

Magic Zach Posted October 24, 2021 Share Posted October 24, 2021 (edited) This issue is still present. I was told that this was actually intentional, and was something modeled for the RR Merlin that no other sim has touched on before? @Yo-YoDo you have any information on this? Is this actually intended, to have the boost fluctuate even with the tank pressurized and the fuel booster on? Or is it just a bug? If it is intended, what makes this phenomenon present in the RR Merlin, but not the Packard Merlin? Edited October 24, 2021 by Magic Zach why not packard's?

Tucker Fleming Posted October 24, 2021 Share Posted October 24, 2021 The phrase Spazzing Out indicates a man of true culture. I hope the problem gets fixed. Link to comment Share on other sites More sharing options...
philstyle Posted October 25, 2021 Share Posted October 25, 2021 Not my reply, but pasted on behalf of someone who does not have ED forums account (from SoW Discord) Quote It might be due to you over boosting the engine and the automatic boost control (p221) preventing excessive boost (combined Air and Supercharger). Not sure what the setting are for the boost control. https://media.discordapp.net/attachments/849930858202529822/902100129144782878/unknown.png?width=1440&height=539 I think on the real engine, oscillations can result from the fact this a mechanical (cam and spring ) system. ED may have modelled that?

Nealius Posted October 25, 2021 Author Share Posted October 25, 2021 (edited) Overboosting at 3000rpm and such a medium boost level? I thought would should have +16 or even +18 boost available at max RPM? Edited October 25, 2021 by Nealius Link to comment Share on other sites More sharing options...

Boost regulator is linked with throttle so when you open up to max boost regulator will maintain 18 boost, but at this alt, you have 12 boost and throttle wide open, so boost regulator is out of operation range, it is simply in off mode.
