B17 Throttle RPM Bug
« on: May 02, 2018, 01:44:30 PM »
after this update, i noticed that if you have split throttle / rpm configs

when you decrease the RPM it decreases the MAN Pressure twice as fast on the B17.

This is not a controller issue, as I have calibrated twice, used different controllers and checked scaling settings as well as looked at the controls moving.

This is a bug.

Controllers tested with.

Saitek X55
Two different Saitek Pro Flight Throttle Quadrants

Steps to reproduce,

Map RPM 1 and Throttle 1 to two different Axis.

Move Throttle to Full, Try to Reduce RPMs watch Manifold fall.

Move RPM to full, Reduce Throttle / Manifold , watch manifold only fall.

Not sure what you mean by "Twice as fast"?

Reducing RPM will reduce manifold pressure also because of less exhaust gasses powering the turbo charger.

no i mean instead of reducing RPM like it used to it decreases Manifold

IE full throttle and full RPM reads on the B17

47 inches of man
2500 rpm

if you decrease rpm to 20 your manifold goes down to 32 inches.

used to be able to decrease RPM while manifold did not change to an extent.

it is in fact different from yesterday

I tested against 3.00 patch 7 and it acted the same. The drop of is do to turbo charger slowing do to less exhaust gases.
This is not a bug.
