I have tried everything.
1.  went to Controllers -> Map Controllers,  Copied mode 1 to mode 2.  My understanding is that *SHOULD* give me basic setup.  No matter what I do, the RPM for the engine never changes.
2.  Did the same thing, went to calibrate joysticks and calibrated everything (I have a HOTAS Cougar and CH USB pedals).  Again, nothing at all.
3. Tried mapping RPM1 and Throttle1 to various axis on the throttle and joystick. 
    Nothing.
Could someone please take a couple of pics of their MapControllers setup for GVs and post them?  I'm at my wits end.
Ouch
