REQ Seperate engine magnetos

[TeeJay82]

when i fly usaaf 2 engine planes,(a20/p38/b25) and one engine gets set on fire i select the engine and turn mags off to prevent fuel detonation in the cylinders.. but as i select the working engine, it stalls as well due to mag switch off.. ive tried all combos with select/unselect engines, but no matter what, the mags are allways on or off for both engines :/

Only me that miss this little feature?

also feathered the engine on fire where possible, and dive, extinguish the fire and level out.. but it aaaaalways gets back on fire (100%) so im wondering if this is due to ingame magnetos who cant be shut off thats causing it, despite the engine is feathered.

only got 100%mix and 120% wich im guessing is autorich and full rich so turning off the fuel supply is not an option :/
